1 CDRH: Minimizing Risk of TSE Agents in Medical Devices CDR Martha O’Lone, RN, BSN CDRH TSE Working Group Chair Infection Control Devices Branch DAGID / ODE / FDA

2 Center for Devices and Radiological Health * Ensure medical device safety and effectiveness * Reduce unnecessary exposure to radiation from medical, occupational and consumer products

3 ObjectiveObjective l Overview of CDRH Measures to Minimize Risk of TSE Agents in Medical Devices Implanted Medical Devices Neurological Devices/General Surgical Instruments In Vitro Diagnostic Devices

4 CDRH Procedures/Approach l Premarket review: 510(k), IDE, PMA l Postmarket surveillance l Scientific Research l Field Inspections l Communicate with industry, health professionals, consumers and foreign governments through letters, guidances and public meetings

5 Implanted Medical Devices Implants: devices with human/bovine tissue Human- cellular wound dressings, human dura mater, bone void fillers, human collagen Animal- absorbable hemostatic agents, dura substitutes, pericardial valves, collagen implants

6 Minimizing TSE Risk for Implanted Medical Devices l Premarket review Source, Manufacture, Sterilization l Guidance Human (CBER and CDRH) Animal (CDRH) General/Specific l Postmarket Surveillance l Inspections

7 Minimizing TSE Risk for Neurological-General Surgical Medical Devices Examples: Neurological medical devices (cranial drill bits) General Surgical instruments (scalpels, scissors, biopsy forceps, retractors)

8 Approaches Used to Minimize TSE Risk for Medical Devices l Premarket review l Guidance-1996 Labeling for Reuse, l Work with CDC- to develop recommendations l Research- Decontamination of medical devices exposed to TSE CBER/CDRH

9 In Vitro Diagnostic Devices l Future-Tests to aid in diagnosis of a patient with variant CJD or infected and at risk for developing CJD l For further questions contact the CDRH Office of In Vitro Diagnostics: Sally Hojvat, Director of the Division of Microbiology Devices:

10 ConclusionsConclusions l CDRH has taken action to minimize risk of TSE transmission in medical devices in the following areas: l Premarket review: 510(k), IDE, PMA l Postmarket surveillance l Scientific Research l Field Inspections l Communicating with industry, health professionals, consumers and foreign governments through letters, guidances and public meetings
