Medtronic recalls InSync III pacemakers due to power-failure problem

The first unexpected power failure in a Medtronic InSync III pacemaker didn't set off the alarm bells. But by the fourth time, doctors at the Minneapolis Heart Institute knew they had to act quickly.

They took their concerns about the discontinued-but-popular pacemaker to Medtronic in late September, after a fourth device among the 448 InSync IIIs implanted at the institute had a power failure.
