Medtronic has recalled (Class 1) its implantable cardioverter defibrillators and cardiac resynchronization therapy defibrillators with glassed feedthrough due to a potential faulty short circuit protection feature. A [recall notice](https://www.fda.gov/medical-devices/medical-device-recalls/medtronic-recalls-implantable-cardioverter-defibrillators-icds-and-cardiac-resynchronization-therapy?ref=fdaweb.com) says the glassed feedthrough devices “may deliver low or no energy output when high voltage therapy is needed due to inappropriate activation of the short circuit protection \[software\] feature.”

The implantable devices are designed to automatically detect and treat life-threatening irregular heartbeats (arrythmias) by delivering an electric shock (cardioversion or defibrillation) to restore a normal heartbeat.

Medtronic says that to date there have be 28 reported incidents, 22 injuries, and no deaths. The company has issued an “Urgent Medical Device Correction Notice” letter that outlines action steps to correct the software issue. It recommended against prophylactically replacing affected devices, noting that the devices will be reprogrammed to minimize the risk of this issue.
