Abbott is recalling (Class 1) its HeartMate Mobile Power Unit (MPU) because of instances where the device experiences a sudden power loss. A [recall notice](https://www.fda.gov/medical-devices/medical-device-recalls/heart-pump-accessory-removal-abbott-removes-heartmate-mobile-power-unit-due-instances-sudden-power?ref=fdaweb.com) says the company has received reports in which the MPU experienced sudden, unexpected performance issues such as not turning on, unprompted shutdown, or suddenly turning off and restarting, with the system controller indicating a “Yellow Wrench” alarm or “No External Power” alarm.

“Abbott has identified that these issues are linked to an electrical component used to manufacture certain MPUs distributed between 4/2024 and 2/2025,” the notice says. “Replacement of impacted MPU devices that have experienced power issues will begin immediately; replacement of impacted MPU devices not currently experiencing power issues will begin in June 2025 or earlier.”

If an impacted MPU experiences a loss of power, the backup battery can support the pump for up to 15 minutes, the notice says. Abbott notes that if the 14V rechargeable batteries are not connected to the system controller within 15 minutes, the pump will lose power and stop, and this could lead to serious adverse health consequences such as hemodynamic compromise, thromboembolism, or death.

The MPU is an accessory of the HeartMate Left Ventricular Assist System, an implantable pump diverting blood from the weakened left ventricle of the heart and pumping it to the aorta, according to the company.
