Computerised tracking systems can be used to identify faulty medical devices, according to a study published in the Journal of the American Medical Association.

US researchers used a computer automated safety surveillance system to evaluate data from more than 74,000 heart procedures that involved the use of seven heart devices.

The researchers analysed the devices looking for three common problems that can occur with each, and found that two may have a safety issue.

One device was an older model stent manufactured by Boston Scientific called the Taxus Express 2. The other was the Angio-Seal STS, which is used to close the holes made in the arteries of the leg during stent implantation.

According to researchers, the tracking system findings can help identify safety risks of medical devices, and can give companies and regulators a good hint at where to identify problems.
