Medical device maker St. Jude Medical is warning doctors and patients about a rare battery defect in some of its implantable heart devices that can cause them to fail much earlier than expected. Almost 350,000 people around the world have defibrillators affected by the issue.

St. Jude’s Implantable Cardioverter Defibrillators (ICDs) and Cardiac Resynchronization Therapy Defibrillators (CRT-Ds) provide electric shocks to help regulate a patient’s heartbeat. The devices are implanted under the skin with wires connecting to the patient’s heart. Patients are outfitted with the devices if they suffer from an unusually slow heartbeat, called bradycardia, or an unusually fast heartbeat, called tachycardia.

The effected devices are:

  • Fortify Assura DR
  • Fortify Assura VR
  • Fortify DR
  • Fortify ST DR
  • Fortify ST VR
  • Fortify VR
  • Quadra Assura
  • Quadra Assura MP
  • Unify Assura
  • Unify
  • Unify Quadra CRT-D

The devices are battery powered, and patients receive a new battery every three months. However, the batteries are lithium-based, and this can cause complications when deposits of lithium build up within the battery. The buildup of lithium deposits – called lithium clusters – creates an abnormal electrical connection that can cause rapid battery failure.

St. Jude said that two deaths have been linked to the problem with 10 more patients losing consciousness after the devices stopped working. The company did say, however, that the issue is rare: “The vast majority of devices sold worldwide have not experienced premature battery depletion.”
