The FDA has the authority to require sponsors to perform a post-approval study (or studies) at the time of approval of a premarket approval (PMA), humanitarian device exemption (HDE), or product development protocol (PDP) application. Post-approval studies can provide patients, health care professionals, the device industry, the FDA and other stakeholders information on the continued safety and effectiveness (or continued probable benefit, in the case of an HDE) of approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

Follow-up Visits and Length of Follow-up All subjects will be assessed annually in years 3, 4, 5, 6, 7, 8, 9 and 10 post reliance or follow up date (±30 days). All visits will occur via telephone. If there is any indication that the subject may be pregnant, by either verbal admission or unusual menstrual events, an office visit will be scheduled and a pregnancy test administered within one month. The duration of follow-up is ten years.
