“Lessons Learned”
Class I
Low risk
Otoscope, opthalmoscope
Class II
Thermometer, blood pressure cuff
Most Covidien devices
Class III
Most stents & pharmaceutical products
High risk
Device Classification
The Food and Drug Administration (FDA) has established classifications for
approximately 1,700
different generic types of devices and grouped them
into 16 medical specialties referred to as panels. Each of these generic types of
devices is assigned to one of three regulatory classes based on the level
of control necessary to assure the safety and effectiveness of the device.

When something isn’t right…
Warning letter
- FDA sends to manufacturer when regulations are violated
- Gives guidelines and timeline for plan of correcting issues
- Reasons
- Poor manufacturing practices
- Incorrect claims or instructions for use (IFU)
Audit
- FDA examines all documentation and internal testing
- Reasons
- Voluntary recall
- Concerns about facility / products
Recalls
- ALL medical device recalls are
posted on the FDA website
- Voluntary recalls
Medical Device Reform
A Health Care Reform Law For The FDA
“Food and Drug Administration Safety and Innovation Act”
History:
- Since 1992, pharma companies pay FDA to review applications
- FDA ↑ new hires = ↓ time to review
- NEW ACT
- ↑ fees for medical device companies
- Implement fees for generic drug companies (=28% of all new fees)
- Inspection changes: making it easier to inspect factories overseas
- Removing requirements that plants in the U.S. be inspected twice a year
- CONCERNS
- medical device companies will be able to appeal reviewers’ decisions to a
supervisor → pressure on reviewers can result in bad decisions
