Study Suggests Flaw in Wires With St. Jude Defibrillator
By: JANET MOORE , Star Tribune
Researchers in Ireland have discovered a possible problem with a heart defibrillator component made by St. Jude Medical Inc. in which wires that run from the device to the heart may poke through the outer coating of their cable.
The study looked at 212 patients in Ireland who received St. Jude's Riata defibrillator lead and found that 15 percent had suffered such an "insulation breach," which could interfere with the device's life-saving therapy. Normal screening of the device or even X-rays may not pick up the breach, and patients would have no outward clue that their lead wire may be compromised.
