Guidant Corporation says that its implanted cardiac defibrillators (ICDs), used by 50,000 heart patients, might be flawed. The company has offered to replace more than half of them. At least two patients have died.
The potential flaw cannot be fixed without removal of the ICDs. The recall includes the Contak Renewal and Renewal 2, Ventak Prizm AVT, Vitality AVT, Renewal 3 AVT, and Renewal 4 AVT ICDs.
A programming change can be made for some of the devices in the doctor’s office to reduce the risk of a short circuit.
