Nearly a month ago, Medtronic’s Sprint Fidelis defibrillator was pulled off the market for defective lead wires. This time another company’s wires have been found to perforate the heart causing bleeding. The pacemaker in question this time is manufactured by St. Jude Medical. The Riata line of defibrillator wires have been found to poke holes in the heart. An editorial in PACE today states that the perforations are not physician related but stem from a defective product design flaw.
