As a result of broken leads in its Sprint Fidelis defibrillator, Medtronic is facing two class action lawsuits-one has been filed in Puerto Rico and another in Canada. The Sprint Fidelis broken lead wires have been linked to 5 deaths as a result of excessive or improper shock delivered to the heart. The defibrillator is supposed to jolt the heart if its rhythm becomes uneven, too rapid, or too slow. The Sprint Fidelis sometimes works when it is not needed and on other occasions it doesn’t send the electrical jolt to the heart.
