Abstract
A implantable pump system comprises an implantable pump motor and an external unit. An inverter comprises respective phases couple to the motor via a cable with redundant conductors for each phase. A controller receives power measurements for all the redundant conductors, which are combined and compared in order to detect failures in the non-redundant components within the motor and windings.
