If the UI membrane is lifted, in certain circumstances when the controller is exposed to water, there is a potential for water ingress into the HeartMate 3 System Controller. Water ingress has the potential to result in problems with the LED display or unresponsive buttons. Recall Start Date: June 28, 2024
