Abstract:
1. A blood pump system for left ventricle assist comprising: an implantable pump unit having a multiphase stator having a plurality of windings connected between respective junctions for driving first, second, and third electrically parallel pairs of redundant conductors in corresponding first, second, and third phases; an external control unit comprising an H-bridge inverter having first, second, and third phase legs; and a percutaneous cable having the first, second, and third electrically parallel pairs of redundant conductors, wherein each conductor pair is connected between a respective phase leg within the external control unit and a respective common junction within the implantable pump unit, wherein the conductors are arranged concentrically around a cable core so that individual conductors of each pair are separated by at least one conductor of a different conductor pair.
