Dangerous Medical Devices

You may think if a doctor prescribes a medical treatment, it's been thoroughly tested. But for one type of treatment, you would be dead wrong.

A Consumer Reports' investigation has found that medical devices-like defibrillators, joint replacements, and even surgical mesh used to treat hundreds of thousands of women-may not be clinically tested at all.

Dr. Stephen Tower is an orthopedic surgeon. When the arthritis in his hip became too hard to bear, he opted for a metal-on-metal hip. But the new hip, he says, caused hiim so much pain, exhaustion, and depression that had to have it removed.

Dr. Tower says, "The tissues around the hip had been destroyed and that metal debris was spreading down my thigh."

Tower says normal friction in the artifical joint caused cobalt, a toxic metal, to be released into his body, leading to serious tissue, heart, brain, and thyroid problems.

Nancy Metcalf of Consumer Reports says, "This particular type of hip was called the ASR XL. It was made of chrome cobalt metal, but it was never clinically tested before the FDA cleared it to be sold. Because of high failure rates and complications like Dr. Tower experienced, it's now off the market."

While metal-on-metal hips have been widely criticized, a Consumer Reports' investigation has found there are other dangerous devices that are being implanted.

Metcalf says, "Hundreds of thousands of women have had mesh slings inserted to support internal organs as they age, like the uterus and bladder. Again, these products were never clinically tested before being marketed for this use."

The FDA's own database shows thousands of complaints about the mesh, including debilitating infections. Yet it's still on the market-not even classified as high-rish.

Metcalf says, "We strongly believe that the FDA should require rigorous testing for implantable devices just like they do for prescription drugs now."

Fortunately for Dr. Tower, after his metal hip was replaced with a plastic and ceramic one, he was eventually able to return to his favorite athletic activities.

Consumer Reports says creating a national registry is essential to be able to keep track of implanted medical devices and to alert patients if there is a problem.

Currently, there is no tracking in the U.S. And it's estimated only a fraction of device problems actually do get reported.
