A study published in The Journal of the American Medical Association (JAMA) highlights the potential public health risks posed by medical devices that undergo limited testing to assess their safety and effectiveness. In 2010 and 2011, 28 medical devices received pre-market Approval (PMA). Manufacturers consider PMA the Food and Drug Administration’s (FDA) most rigorous approval process for medical devices before they allow them to sell on the market.
These devices require PMA because of their high risk. Also, they are not substantially similar to other medical devices already on the market. Once approved, they are generally considered Class III medical devices. It is very difficult for individuals injured by Class III medical devices to sue the manufacturer. This is because courts, including the United States Supreme Court in Riegel v. Medtronic, have held that individual claims are largely preempted by federal law. Our firm can represent many clients who have suffered injuries from Class III medical devices.
JAMA Study
The recent JAMA study raises questions about how rigorous the PMA process really is. Of the 28 medical devices that received PMA from the Food and Drug Administration (FDA) in 2010 and 2011, most had an average of 2 pre-market clinical studies. Only one of those two studies focused on the long-term safety and efficacy of the medical device. The JAMA study found that only 6 of the 33 post-market studies were completed. The rigorous PMA process does not appear to be as complicated as advertised. This study questions the preemption arguments made for Class III medical devices that undergo PMA.
Experienced Medical Device Lawyers
As we have previously blogged, 99% of medical devices that are on the market do not even undergo PMA. The other 99% of medical devices are cleared through the 510 (k) process, which requires no pre-market clinical studies. All medical devices that Perdue & Kidd is litigating have undergone 510 (k) clearance, including transvaginal mesh, metal-on-metal hip implants, and Zimmer knee implants.
