Boston Scientific Corp said on Thursday it found problems with three older models of its implantable heart defibrillators that can prevent the devices from performing life-saving functions. The world's second largest maker of heart devices, which has been struggling with regulatory and product issues for the last several years, confirmed a Reuters report on Wednesday that the company would issue an advisory to doctors on three models of its implantable heart defibrillators, known as ICDs. In a telephone interview, Boston Scientific CEO Ray Elliott told Reuters this action is likely the end of the problems associated with the Contak Renewal 3 & 4 and Vitality HE ICDs manufactured between January 2006 and November 2007. They are not sold anymore and are not in hospital inventories.
