1. A mechanical circulatory support system comprising:
an implantable blood pump comprising a rectifier and a direct current (DC) powered pump control unit configured to control the implantable blood pump according to one or several stored instructions, wherein the rectifier is configured to generate a DC electrical power supplied to the DC powered pump control unit from an alternating current (AC) electrical power;
a driveline electrically connected to the implantable blood pump, wherein the driveline comprises a plurality of power transmission wires and a communication wire, and wherein the communication wire is reconfigurable as a power transmission wire; and
an external controller electrically connected to the plurality of power transmission wires and the communication wire, wherein the external controller is configured to output the AC electrical power for transmission to the rectifier through the plurality of power transmission wires in a first operational mode and output the AC electrical power for transmission to the rectifier through the communication wire and at least one of the plurality of power transmission wires in a second operational mode.
