Guidant Corp., Indianapolis, said the pacemakers it recalled in the summer of 2005 could fail at a higher rate than previously projected. Between 0.31% and 0.88% of the devices might fail, instead of between 0.17% and 0.51%, the company said. Guidant announced in July 2005 that a seal used in some pacemakers could degrade, letting in liquid, and the company subsequently identified a second population of devices that might be at risk. There have been a total of 145 reported incidents among the 78,000 devices produced from October 1997 to October 2000 that are at risk, for a reported incident rate of 0.19%. Guidant estimates that 16,000 devices are still implanted in patients. The company has been the subject of a bidding war between Boston Scientific and Johnson & Johnson. Most recently, Guidant's board endorsed Boston Scientific's $27 billion bid, but J&J may make a counteroffer. -- by Joseph Mantone
