The FDA has been an active and crucial government body in the case of medical device security. In a way the research community are pushing the FDA for stringent rules or a checklist to maintain security in medical devices by manufactures.
The essential link here is the website of FDA, that have a separate listing of Medical Devices! It delves into the entirety of medical devices from research to events to safety issues and much more. Another additional link I am particularly interested in is the recalls section. This would help me in my project as it provides data for study about causes of recalls. I am pursuing the same for my project.
