In the past two years, the FDA has issued several important new guidances that radically altered the rules for medical device manufacturers on the inter-related topics of biocompatibility, reprocessing, and sterilization. This master’s thesis discusses various aspects of these policy changes by the FDA and the potential consequences for medical device manufacturers.

Text of the abstract: The U.S. Food and Drug Administration ("FDA") regulates all medical devices in the United States. As part of its regulatory duties, the FDA provides guidance documents on various regulatory topics as mandated by the U.S. code of federal regulations. Since 2015, the FDA has begun to issue many substantial revisions to their guidance documents that directly affects the regulatory framework on biocompatibility, reprocessing, and sterilization.
These regulatory issues are of paramount importance for many companies because of the potential high costs involved in changing their internal design, controls, manufacturing, and quality systems. This master’s thesis examines the various changes made by the FDA in recent years on the inter-related topics of biocompatibility, reprocessing, and sterilization. Some of the major changes by the FDA involve an increase in the importance of chemical characterization, a reduction in the use of animal testing, a requirement for an independent validation of the user instructions for reusable devices, and increased usability testing.
The principal reasons for these major policy changes by the FDA are shown to be the major device scandals that recently involved duodenoscopes, metal-on-metal hip implants, and vaginal surgical mesh implants. Along with several other regulatory failures that made national news headlines in the United States, the FDA began to revise several of their previous medical device guidances. The information from this master’s thesis can be used by medical device developers and manufacturers, especially when they are located outside of the United States and lack sufficient regulatory affairs resources to provide independent advice and recommendations on these important FDA changes. A thorough analysis is made of the new FDA guidances to clarify several potentially difficult questions for medical device manufacturers, specifically the following: (1) "Use of International Standard ISO 10993-1, ‘Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process", (2) "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling", and (3) "Submission and Review of Sterility Information in Premarket Notification (510(k)) Submissions for Devices Labeled as Sterile". This master’s thesis is intended to provide not only an overview of the current FDA requirements, but to function as a guide for both researchers and engineers to improve their medical device design and development process.
