Medtronic Recalls HeartWare Ventricular Assist Device

Medtronic has recalled its HeartWare Ventricular Assist Device (HVAD system) because of the possibility for an interruption to occur in the electrical connection between the system’s power source (battery, AC adapter, or DC adapter) and the HVAD controller. An interruption to the electrical connection, which occurs when the power source is still physically connected, is caused by “oxidation on the connecting surfaces between the power source connector and the controller’s power source socket,” a recall notice says. “Interruptions to the electrical connection could cause unintended intermittent electrical disconnection, which could result in a pump stop. A pump stop could cause patient harm such as exacerbation of heart failure symptoms, or symptoms such as mild weakness, dizziness, anxiety, nausea, loss of consciousness, or death.”
