Medtronic Mechanical Circulatory Support has expanded a Class 1 recall of its Ventricular Assist Device Controllers and DC Adapter to now include all controllers. The device helps deliver blood from the heart to the rest of the body. It is used in patients who are at risk of death from end-stage left ventricular heart failure and who are waiting for a heart transplant. The recall was ordered due to the potential for a loose power connector which may cause the rear portion of the pump’s driveline connector to become separated from the front portion, a [recall notice](https://www.fda.gov/MedicalDevices/Safety/ListofRecalls/ucm556629.htm?ref=fdaweb.com) says. “A loose connector may allow moisture to enter the controller causing corrosion, electrical issues, reduced speaker volume and connection failures,” it adds. “If the speaker volume is decreased, the patient may not hear the alarm. If there is a loss of connection, the pump may stop which could cause serious adverse health consequences, including death.”
