Batteries/Medical/Saftey 060710

(July 2006) Boston Scientific recalls some pacemakers and implantable cardioverter defibrillators (ICDs)  in late June 2006.  The products were manufactured by the company’s recently acquired cardiac rhythm management  business  - Guidant.  Pacemakers  recalled include Insignia and Nexus pacemakers,  as well as  the Contak Renewal TR/TR2 cardiac resynchronization   pacemaker.   ICD recalls include the Ventak, Prizm2, Vitality and Vitality 2.

As of the date of the announcement, 27,000 already implanted devices could potentially have a problem .  The recall is a result of a a capacitor (built by an outside supplier) which  can cause a malfunction in the devices,  including premature battery depletion.

To date five patients  have had problems although there have no deaths.  It is recommended by Boston Scientific that patients having these implantable devices see their physicians at the earliest opportunity.
