Each prescription drug you take has a unique code that the government can use to track problems. But artificial hips and pacemakers? They are implanted without identification, along with many other medical devices. In fact, the FDA doesn’t know how many devices are implanted into patients each year – it simply doesn't track that data.

The past decade has seen numerous high profile cases of malfunctioning medical devices, which have led to injury or even death. Critics say the FDA's minimal monitoring of devices contributes to these problems.

“If you’re lucky, you might find a sticker on the operating room note that was left over from the product,” said Richard Platt, who runs the Harvard Pilgrim Health Care Institute. Otherwise, there is little way of knowing what device was used.

Right now, the FDA depends mostly on voluntary reports from doctors, patients, manufacturers and hospitals to notify them of problems with devices already on the market.

But my friend was not writing about Sarah Burke. He wanted to alert me to another fundraiser, this one on Alabama’s Gulf Coast, to help pay for the mounting medical expenses for a beautiful 13-year-old girl fighting for her life at USA Children’s & Women’s Hospital in Mobile, Ala.

In late November, Caroline Richmond was rushed to the hospital after collapsing on the way home from school. Doctors quickly determined she’d had a stroke and required immediate surgery. The bad news just kept coming. The ...
