A Dear Healthcare Professional Letter has been issued by Medtronic International Ltd to inform healthcare professionals on the updated cleaning instructions for the HeartWare Ventricular Assist Device (HVAD™) Controller AC Adapter, DC Adapter, and Battery. These instructions include advice not to clean the pins of the power source connectors as attempts to clean the pins of the connectors may damage the HVAD™ system components. The pins of the power source connectors are coated with a lubricant, that should not be removed as it is intended to help prevent unexpected power switching. Power switching can occur when there are transient interruptions to the electrical connection with the HVAD™ System power sources, which may result in potential performance issues from damaging the power source connectors, ranging from negligible harm to an unanticipated VAD stop. Healthcare professionals are advised to ensure that their patients receive the updated cleaning instructions for the HVAD™ system power source connectors. Please refer to the letter for details.
