A method of controlling operation of an implantable blood pump includes attempting to restart a stopped implantable blood pump for a predetermined number of attempts with either power from an internal battery of a controller in communication with the implantable blood pump or transcutaneous energy transfer system (TETS) power in communication with the internal battery and the implantable blood pump. Following the predetermined number of attempts, the method includes pausing attempting to restart the implantable blood pump and begin attempting to recharge the internal battery with TETS power.

Method for pump start in a fully implanted LVAD system when multiple power sources may be present

In an implanted medical device system, an internal controller, external power transmitter and methods for performing battery conditioning are disclosed. According to one aspect, an internal controller includes processing circuitry configured to cause conditioning of an internal battery of the internal controller responsive to a direction from an external power transmitter in radio communication with the internal controller.
