Adopting new medical technology / Annetine C. Gelijns and Holly V. Dawkins, editors ; Committee on Technological Innovation in Medicine, Institute of Medicine
Collection documents the development of the Holter Monitor, a portable device for continuously monitoring heart activity for an extended period, through engineering logbooks, drawings, operator manuals, correspondence, photographs, sales brochures and catalogs, biographical information about the engineering staff who worked on the monitor, patents and trademarks, and marketing and sales materials.
Scope and Contents:
The collection includes engineering logbooks, drawings, operator manuals, correspondence, photographs, sales brochures and catalogs, biographical information about the engineering staff who worked on the monitor, patents and trademarks, and marketing and sales materials documenting the development of the Holter Monitor, a portable device for continuously monitoring heart activity.
The records document the successful collaboration of an independent inventor and a manufacturing firm to identify problems, develop solutions and bring to market diagnostic technologies. Bruce Del Mar's role as an innovator and collaborator with Holter is especially important, because Del Mar's work spurred the development of an entire diagnostic industry. In addition, the records also chronicle how "Holter technology" was affected by progressive technological innovations in the industry, as vacuum tubes were replaced by transistors, as microprocessors gave way to microchips and circuit boards, and as analog recordings were replaced by digital formats.
Documenting manufacturing developments (highs and lows) and marketing considerations is an important element in better understanding the invention process. Del Mar Avionics was the first to design and manufacture instrumentation for long-term monitoring of the human heart for the medical profession. Today, Holter Monitors continue to be an important diagnostic tool for monitoring the health of the heart.
Series 1, Historical Background, 1951-2010 and undated, consists of biographical materials for Bruce Del Mar, founder of Del Mar Avionics, company histories, copies of the Del Mar Avionics newsletter Pacemaker, employee information, newspaper clippings and ephemera, and photographs of some employees. The employee information contains a 1979 handbook, explaining company policies and the benefits of employment with Del Mar Avionics and a 1951 memo detailing overtime working hours for women, presumably from Douglas Aircraft, where Bruce Del Mar was employed.
Series 2, Del Mar Avionics Engineering, 1958-1976, is divided into three subseries, Subseries 1, Correspondence, 1965-1976; Subseries 2, Reports, 1964-1969; and Subseries 3, Drawings, 1958-1968. The documentation consists primarily of correspondence from the engineering department, 1965 to 1976, related to the development, design, budgeting, testing, and marketing of the Holter Monitor. The majority of the documentation is correspondence and is written by engineering staff members, but also included are quotation requests, trip reports, and technical reports. Correspondence between Holter and Del Mar about the development of the Holter Minotor is in Series 6. The drawings, 1958-1968, include six drawings (22" x 34" or smaller) for Avionics Research Products projects (panel assembly, chassis assembly, and battery chargers for model 602), and Electromation Company (degausser single coil).
Series 3, Patents and Trademarks, 1965-2002 and undated, consists of copies of patents by Norman J. Holter, W.E. Mills, and W.E. Thornton, Cliff Sanctuary. and Isaac Raymond Cherry related to the development of the Holter Monitor. Also included are lists of United States patents issued to Del Mar Avionics employees, as well as lists of registered trademarks and activities for Del Mar Avionics and copies of trademarks issued to the company.
Series 4, Product Literature, 1968-2010 and undated, consists of product literature for Del Mar Avionics products and some of its competitors. The product literature for Del Mar Avionics is arranged chronologically by model number, and the competitor literature is arranged alphabetically. All of the product literature is related to medical instrumentation with the exception of the Hydra Set, a precision load positioner which is the only product Del Mar Avionics sells today.
Series 5, Sales, 1967-1985, consists of price lists, price catalogs (both domestic and international) and sales objectives for medical instrumentation sold by Del Mar Avionics.
Series 6, Holter Monitor Materials, 1958-2005 and undated, is divided into three subseries, Subseries 1, Background Materials, 1958-2005 and undated; Subseries 2, Model 445, 1974-1978; and Subseries 3, Model 660, 1967-1978 and undated, and consists of materials documenting the relationship between Norman J. Holter, an inventor, and Del Mar Avionics.
Holter and Wilford R. Glassock were issued United States Patent 3,215,136 on November 2, 1965 for the Electrocardiographic Means. Dr. Eliot Corday introduced Holter to Bruce Del Mar, founder of the Del Mar Avionics Corporation in Irvine, California. Del Mar engineers developed the "electrocardiocorder" for clinical use, producing a commercially viable monitor which came to be known as the Holter Monitor Test. Further refinements led to the creation of a "minimonitor" in 1968 which was described by Holter as being the "size of a cigarette package." Commercial production of the Holter minimonitor, AVSEP, Jr., began in 1969. The Holter Research Foundation ultimately sold exclusive rights to their patents to Del Mar Engineering Laboratories.
The materials include biographical materials about Norman J. Holter, journal articles about the Holter Monitor, correspondence, engineering notebooks, a licensing agreement, product literature, reports, price lists, catalogs, operating manuals and specific information about the Dynamic Del Mar Avionics ElectroCardioCorder (Model 445), 1977, and the ElectroCardioScanner (Model 660), 1971. Both models were developed by Del Mar's medical device manufacturing staff. The licensing agreement and correspondence detail in chronological order the relationship between Norman Holter and Del Mar Avionics, specifically president Bruce Del Mar, in the rapid commercial marketing and development of Holter's electrocardiorecorder. Although Holter assigned exclusive rights to his patent to Del Mar Avionics, he was involved in the design and development process, albeit from a distance. The engineering staff at Del Mar kept Holter informed, and it is clear that Holter regularly visited the company.
The engineering notebooks relate to the models 445 and 660. The notebooks were maintained by engineering staff members D. Anderson, N. Mohammedi, Ray Cherry and Fike. The notebooks are handwritten, although in some instances memos and other information have been inserted. For example, N. Mohammedi's notebook documenting Model 445 contains black-and-white prints, magnetic tape samples, and recorder tape (EKG graph paper) samples with data from the monitor. The notebooks are bound and paginated, and individual pages are stamped sequentially.
Series 7, Slides, circa 1990s, consists of color slides used for presentations by Del Mar Avionics staff to discuss and promote the marketing of the Holter Monitor.

Biographical / Historical:
Norman Jefferis "Jeff" Holter (1914-1983) was born in Helena, Montana, to a prominent Montana pioneering family. After attending public schools in Helena, he earned master's degrees in chemistry from the University of Southern California (1938) and physics from the University of California, Los Angeles (1940). During these years Holter also organized Applied Micro Sciences, a scientific photography business, and began working with Dr. Joseph A. Gengerelli of UCLA on nerve stimulation in frogs and brain stimulation in rats. Holter's interest in studying electrical activity in humans in their daily activities without touching them, spawned his lifelong pursuit to develop the Holter Monitor.
During World War Two, Holter served as a senior physicist for the U.S. Navy's Bureau of Ships, conducting research into the behavior of ocean waves in preparation for wartime amphibious operations. After the war, in 1946, Holter headed a staff of oceanographic engineers at Bikini Atoll during Operation Crossroads, the first postwar atomic bomb tests, measuring wave actions and underwater disturbances caused by the explosions.
Because of demands of his family's business affairs, Holter returned to Helena in 1947 to continue his research activities. In 1947 he formed the Holter Research Foundation, with a laboratory originally located in the rear of the Holter Hardware Company building. From 1956 to 1971 the laboratory facilities were located in the Great Northern Railroad depot building in Helena. The foundation was initially funded by Holter and other members of his family, but in 1952 Holter began to receive grants from the National Institutes of Health (NIH).
Holter continued his collaboration with Dr. Gengerelli of UCLA in attempting to transmit information, primarily brain waves, by radio. Holter turned his attention from the brain to the heart because the heart's greater voltage made the electronics easier, and because heart disease was far more prevalent than cerebral disease. Holter's introduction to Dr. Paul Dudley White (1886-1973), a renowned physician and cardiologist, helped convince him to focus his research on recording electrical activity from the heart. Holter's goal was to radio broadcast and record the more obvious electrophysiological phenomena occurring in humans while carrying on their normal activities, rather than having to lie quietly on a couch.
The first broadcast of a radioelectrocardiogram (RECG) took place circa 1947 and required eighty to eighty-five pounds of equipment, which Holter worn on his back while riding a stationary bicycle. This was not practical and in no way could be worn by a patient. The initial transmitter and receiver required that the subject remain in the general area of the laboratory, so a portable and lighter RECG receiver-recorder had to be developed.
Next, Holter created a briefcase-like device that could be carried by a patient. By using very thin magnetic recording tape, twenty-four hours of RECG could be captured on a reel five inches in diameter. The initial method of examining the voluminous records from the tape recordings developed by Holter was called Audio-Visual Superimposed ECG Presentation (AVSEP). AVSEP made it possible to examine twenty-four hours of RECGs in twenty minutes, with signals being presented visually on an oscilloscope and audibly through a speaker.
With the development of transistors, radioelectrocardiography was made obsolete, and it became possible for the amplifier, tape recorder, temperature-control circuits, motor speed control circuits, and batteries to be placed in a single unit small enough for a coat pocket or purse. In 1952, Holter succeeded in creating a small unit that weighed 1 kilogram. Wilford R. Glassock, a senior engineer working with Holter, traveled to Cedars of Lebanon Hospital (now Cedars-Sinai Hospital of Los Angeles) in 1962 to demonstrate the Holter monitor system and discuss making it more practical. At Cedars, Dr. Eliot Corday observed the practicality of the system and not only embraced the technology, but collaborated with Holter's team and was an early promoter of the technology to both industry and physicians. Holter and Glassock were issued US Patent 3,215,136 on November 2, 1965 for the Electrocardiographic Means.
As articles describing the foundation's invention of these devices began to appear in the professional literature, there was considerable demand from doctors and hospitals for the equipment. Dr. Corday introduced Holter to Bruce Del Mar, founder of the Del Mar Avionics Corporation in Irvine, California. Del Mar engineers developed the "electrocardiocorder" for clinical use, producing a commercially viable monitor which came to be known as the Holter Monitor Test. Further refinements led to the creation of a "minimonitor" in 1968, which was described by Holter as being the "size of a cigarette package." Commercial production of the Holter minimonitor, AVSEP, Jr., began in 1969. The Holter Research Foundation ultimately sold exclusive rights to their patents to Del Mar Engineering Laboratories.
Later known as Del Mar Avionics, a team of engineers diverted their attention from successful manufacturing of military weapons training devices to focus on improving the speed and accuracy of computerized ECG analysis and they became the acknowledged leader in Holter monitoring technology for over 40 years. In 1969, because of the increased amount of required paper work and red tape, Holter canceled the grant funding his foundation had been receiving from NIH. He was also in constant conflict with the Internal Revenue Service over the foundation's non-profit status, rights to patents, and commercial production of equipment. The foundation continued to maintain a laboratory and conduct varied scientific work, but on a much smaller scale. The Holter Research Foundation, Inc. was dissolved in 1985, two years after Holter's death.
Del Mar Avionics was founded on January 9, 1952, as Del Mar Engineering Laboratories in Los Angeles, California by Bruce Del Mar, who led the development of aircraft cabin pressurization systems. Del Mar was born in Pasadena, California in 1913. An engineer, inventor, entrepreneur and businessman, Del Mar graduated from the University of California, Berkeley (1937) with a Bachelor of Science degree. Del Mar worked for Douglas Aircraft (1933-1951) as a research engineer on many projects before founding Del Mar Engineering Laboratories. In 1938, Del Mar married Mary Van Ness. The couple had two daughters, Patrica Jean Parsons and Marna Belle Schnabel.
In 1958, Del Mar formed a wholly-owned subsidiary, Electromation Inc., which manufactured tape recording and communication equipment. He later established, Aeroplastics Corporation to manufacture plastic products and Avionics Research Products Corporation to develop and produce biomedical instrumentation. By the mid-1960s, the company had become a leading U.S. Defense Department prime contractor in the development and production of aerial tow target systems for weapons training and instrumented ground targets for scoring air-to-ground automatic weapons delivery. It also produced helicopter target drones and helicopter flight trainers for the U.S. Army.
In 1961, the company entered the growing medical instrumentation market with the development of the first long-term ambulatory monitoring systems.
In 1965, the company introduced the Hydra Set Load Positioner that controls the precise vertical positioning of loads up to 300 tons (272,000 kg) in increments as small as 0.001 inch (0.025mm). This unique product, mounted between the load and the crane (or hoist), permits precise mating and de-mating of critical components, thus eliminating unforeseen damage to valuable loads. Hydra Set Load Positioners are in use worldwide in the aerospace, military/commercial aviation, nuclear and fossil fuel power generating industries and in various industrial applications. In 1975, the company, then re-named Del Mar Avionics, moved to its current location in Irvine, California.

Scope and Contents:
The papers document Dr. Ernst P. Boas and his work with Benjamin Liebowitz and Dr. Ernst F. Goldschmidt to develop the cardiotachometer (US Patent 1,816,465), a device to measure patients' heart rates for long periods of time. Boas and Liebowitz were also assisted in their work by by Dr. Alfred N. Goldsmith, Julius Weinberger, Theodore A. Amith, and George Rodwin of the Radio Corporation of America (RCA). The RCA team was able to work out the theoretical and practical solutions for the amplifier, an important aspect for the device.
The papers include Dr. Boas's correspondence, patient experiment data, articles, and reprints of journal articles authored by Dr. Boas and with others that relate to the development of the cardiotachometer.
Series 1, Cardiotachometer Materials, 1926-1948, consist of the US patent issued to Boas, correspondence and writings that relate to the development of the cardiotachometer
Subseries 1, Correspondence, 1926-1934, consists of correspondence, invoices, receipts, and business cards, that relate to the development of the cardiotachometer and responses from physicians about its use. The majority of the correspondence relates to the development of the cardiotachometer and documents Boas's communications with companies who supplied parts (relays, wiring, contact devices, counters) such as the Weston Electrical Instrument Corporation, Veeder Manufacturing Company, A. Wittnauer Company (watchmakers), C.H. Stoelting Company, and Radio Corporation of America.
Subseries 2, Writings, 1928-1935, consists of articles written by Boas and with others related to the cardiotachometer and heart issues. Most of the articles are reprints from medical journals such as American Journal of the Medical Sciences, Archives of Internal Medicine, American Medicial Association, Journal of Clinical Investigation, The American Heart Journal, and the Journal of Mount Sinai Hospital.
Series 2, Patient Experiment Files, 1928-1929, consists of cardiotachometer experiments Dr. Boas conducted at Montefiore Home and Hospital in New York. The documentation consists of data for 48 patients, but the experiment numbers which were assigned to each patient in the study indicate more patients participated. The majority of patients are male, and the series is arranged by experiment number.
The files contain an overall health history (name, occupation, education, marital status, hobbies, sex, birth date, family history, habits and hygiene (sleep, diet, bowels, and menstruation), and past illnesses; physical examination (addressing teeth, tonsils, heart, joints, liver, spleen, lungs, etc.); diet sheet (types of foods eaten along with average pulse rates); measurements (height, arm length, leg length), cardiotachometer data (time, counter reading, rate, body position, room temperature, and remarks), cardiotachometer tape readings, and in some instances correspondence. A follow-up survey form was sent to patients by Dr. Boas, who participated in the experiment. The survey questions included issues such as mental work, dreaming, morning wake time, and preferences for staying in bed.
Ernst Philip Boas was born on February 4, 1891 in Worcester, Massachusetts where his father, Franz Boas, held a docentship in anthropology at Clark University. Later, the family (including Ernst Boas's mother, Marie Krackowizer Boas; his three sisters, Helene, Gertrude, and Franziska; and his brother, Henry, moved to the New York City area.
Boas attended the Ethical Culture School through high school and then went on to receive his B.S. from Columbia University in 1910. He remained at Columbia to receive his M.A. in 1912 and his M.D. in 1914, the latter from the College of Physicians and Surgeons, where he graduated first in his class.
After some trouble finding an internship, apparently because of anti-Semitism, Boas became an intern at The Mount Sinai Hospital from 1914 to 1916. In 1917, he was appointed Instructor in Pathology at the College of Physicians and Surgeons of Columbia University. On August 6, 1917, he was drafted into the Army as First Lieutenant in the Medical Section of the Officers' Reserve Corps and was appointed Captain on April 20, 1918. While in the Army (including some duty in France), he served as a cardiovascular specialist.
When Boas was honorably discharged from the Army on 24 May 1919, he began his first private practice from an office in his home on West 96th Street in New York City. He practiced there until 1921 when he joined the staff of the Montefiore Hospital for Chronic Diseases as Medical Director. From 1920 to 1921, Boas was Instructor in Physiology at the College of Physicians and Surgeons of Columbia University. Later, from 1926 to 1951, he taught post-graduate courses in diseases of the heart at the College of Physicians and Surgeons.
In 1929, Boas left the medical directorship of Montefiore Hospital but retained the position of Attending Physician there for one year, from 1929 to 1930. Also in 1929, Boas moved to The Mount Sinai Hospital, where he was Associate Physician until 1951, at which time he became a consultant to the hospital.
Meanwhile, Boas resumed his private practice in 1929 (he was certified as a cardiovascular disease specialist by the American Board of Internal Medicine in 1941), opening an office at 41 West 83rd Street. He later established a permanent office at 1185 Park Avenue, where he entered into a partnership with Hyman Levy in 1949. One of Boas's sons, Norman F. Boas (also a physician), was his assistant from 1949 to 1951. Some of Boas's famous patients included William Laurence, science editor of the New York Times; Charles C. Burlingham, New York lawyer and politician; Sidney Hillman, President of the Amalgamated Clothing Workers of America; Henry A. Wallace, a United States cabinet official and presidential candidate; Karl Menninger, founder of the Menninger Clinic; and Dr. Felix Adler, founder of the Ethical Culture Society.
From 1937 to 1943, Boas was a Special Lecturer at the Teacher's College of Columbia University where he specialized in the education of the handicapped. From 1938 to 1951, he was Assistant Clinical Professor of Medicine at the College of Physicians and Surgeons.
Boas was a prolific writer of articles and books on scientific topics (such as cardiology), as well as on topics in the popular media, such as geriatrics and chronic illness. Many of his publications advocate compulsory national health insurance. He served as Associate Editor of Modern Hospital from 1923 to 1929. Some of his books include Treatment of the Patient Past Fifty, The Unseen Plague--Chronic Disease, and The Heart Rate. This latter book grew out of Boas's research with Ernst F. Goldschmidt in developing the cardiotachometer, an electronic device that measures the heart rate continuously over many hours. Other research included his discovery of the calcification of the pineal gland; studies of neurocirculatory asthenia in soldiers in World War I; studies of the physiology of capillaries; and studies on cholesterol and its role in the pathogenesis of arteriosclerosis.
Boas also served as a medical consultant to numerous organizations and health care institutions, including Beth Israel Hospital of Passaic, New Jersey; the Group Health Cooperative, Inc.; the New York Guild for the Jewish Blind; the Sidney Hillman Health Center (where he directed a large research program on atherosclerosis); Irvington House; Lexington Hospital; Long Beach Hospital; Moosehaven; the New York Metal Trades Council and Hotel Association; and the Workmen's Circle.
Boas was involved with city, state, and federal organizations that dealt with health care. He was Chairman of the Committee on Chronic Illness of the Welfare Council of the City of New York. His work with this committee encouraged the construction of the Municipal Hospital for Chronic Diseases (now called Goldwater Memorial Hospital) on Welfare Island, as well as the elimination of many of the almshouses there. He also served on the Advisory Council of the New York City Department of Health and on the General Advisory Committee for the Cardiac Program of the New York State Department of Health. He was a consultant to the Social Security Board of the United States Federal Security Agency. He also testified in compensation hearings to show that heart attacks may result from unusual effort or trauma.
Besides his purely medical work, Boas was deeply involved in social causes. He worked with such agencies as the China Aid Council, Inc.; the Emergency Committee in Aid of Displaced Foreign Medical Scientists (serving as Secretary in 1945); the Committee of Physicians for the Improvement of Medical Care, Inc.; the National Committee for Resettlement of Foreign Physicians; the Physicians Committee of the National Refugee Service (serving as Chairman in 1943), and the United Service for New Americans, Inc. He founded The Physicians Forum, Inc., in 1939, to study and discuss health care issues, resist McCarthyism, and counter the American Medical Association's opposition to national health insurance. He also continued to work against discrimination in any form and was instrumental in the appointment of African-American physicians and nurses to hospital staffs.
He was a member of the American Heart Association, the American Medical Association, the American Society for the Study of Arteriosclerosis (founding member), the Authors' Guild, the Child Study Association of America, the Committee for the Nation's Health, the Committee of Citizens Against the Feinberg Law (a law to eliminate subversives from the New York state public school system), the Harvey Society, the Medical Society of the County of New York, the National Medical Committee of the NAACP, the New York Academy of Medicine, the New York Heart Association, Inc. (founding member and Chairman), the New York Tuberculosis and Health Association (Chairman of the Heart Committee), and the United States Committee, Inc. (founding member), an organization created in support of the World Medical Association. He also belonged to the honorary societies of Alpha Omega Alpha, Phi Beta Kappa, and Pi Gamma Mu.
Boas died on March 9, 1955 in New York City of pancreatic cancer. He was survived by his wife, Helene Tuthill Sisson Boas, and his children, Donald P. Boas, Norman F. Boas, and Barbara G. Crutchley.

Biographical / Historical:
Dr. InBae Yoon (1936-2014) was a prolific Korean American inventor of surgical devices and instrumentation. He was born in Korea during the Japanese Occupation (1910-1945) and attended the Yonsei University School of Medicine, earning his medical degree in 1961. From 1961 to 1964, Yoon served as medical officer in the South Korean Navy, and in 1964 he participated in a program developed to match Korean medical doctors with United States hospitals and medical schools. As a result, Yoon immigrated to Baltimore, Maryland to conduct his rotating internship and general surgical residency at Church Home and Hospital. During his residency, Yoon switched his training from general surgery to obstetrics and gynecology and became fascinated by laparoscopy, a method of surgery performed using a scope placed through the umbilicus, sometimes with other small incisions in the abdomen. During this period he was exposed to tubal ligation, one of the few surgeries done laparoscopically at the time. Observing some of the injuries and complications from these early laparoscopic procedures he became interested in safer laparoscopic methods. After completing his residency in 1969 and finishing a yearlong fellowship, he joined a private practice. In 1973 he then joined the John Hopkins University School of Medicine as an assistant professor in the Department of Obstetrics and Gynecology where he explored new laparoscopic techniques and procedures.
Yoon became convinced that laparoscopic or "keyhole" surgery was the future. His first invention, the Yoon Ring, was developed between 1972 and 1974, with the patent being issued in 1975 (US Patent 3,870,048). The Yoon Ring system, manufactured with KLI Incorporated, provided a safer method for laparoscopic tubal ligation by applying a silastic ring around the fallopian tube to prevent pregnancy. This simple mechanical method of tubal ligation avoided many of the complications associated with other tubal ligation techniques that utilized electrocautery. Yoon began to see further potential for the use of laparoscopy and from 1975 to 1985, he focused on inventing safety systems for laparoscopic procedures, including safety trocars, safety needles, and safety catheters, which all aided in different aspects of laparoscopic surgery. Yoon spent much of the late 1980s to the early 2000s, working on new innovations such as retractable penetrating instruments, suture tie instruments, cavity stents and expanders, as well as making modifications to previous safety system designs. During this period, Yoon investigated and sought out the assistance of a few large instrument manufacturing companies, such as Richard Wolf GmbH, Olympus, and Cabot Medical in an effort to bring his trocar designs to the market without success. In 1985, Yoon then incorporated his own company, Yoonitech, Inc. to pursue his inventions. In 1988, Yoon established a relationship with Johnson and Johnson, specifically the subsidiary of the company, Ethicon, which later became Ethicon Endo Surgery (EES) and licensed his shielded trocar patent (US Patent 4,535,773) to bring his product to market. From 1995-2005, Yoon continued to collaborate with EES for the production of instruments and techniques for laparoscopy and endoscopy. Dr. Yoon passed away on December 30, 2014. After 5 decades of focusing on this innovative approach to surgery, he amassed over 200 U.S. patents for his work.
