Summary:
InBae Yoon was a Korean American inventor. He specialized in OB-GYN surgery, and his inventions aided in the safety of laparoscopic and endoscopic surgery. The papers include personal documents, corporate agreements and licenses, technical drawings, patent applications, correspondence, project proposals, and methods and procedures.
Scope and Contents:
The collection documents Dr. Yoon's life and career as a surgeon and his invention and development of numerous tools, instruments and procedures. The collection specifically focuses on three inventions: the "Yoon Ring", a device for tubal ligation for women patented in 1975; a penetrating instrument with safety shield, and method for introducing a portal sleeve into a cavity in the body, patented in 1985; and surgical clips and applicator, patented in 1992. All three were manufactured and widely used. The contents include invention notebooks, sketches, photographs and slides, correspondence, patents, patent applications, legal papers, business papers, articles and clippings, reference files, and some audiovisual materials.
Arrangement:
The collection is arranged into 6 series.

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.
