Methods and apparatus for controlling the operation of, and providing power for and to, implantable ventricular assist devices which include a brushless DC motor-driven blood pump, are disclosed. In one embodiment, a control system (10) for driving an implantable pump (12) is provided. The digital processor (92) is responsive to data associated with the operation of the pump received at the data transfer port (48), and from the program data stored in memory (94), (i) to determine therefrom, the identity of the pump, (ii) to determine therefrom, electrical characteristics and features of the identified pump, and (iii) to adaptively generate and apply to the data port, control signals for driving the identified pump. Latch mechanisms, an elongated flexible electrical cable (51) with a strain relief segment (55), and a lower housing portion (B) that is heavier than an upper housing portion (A), may also be provided with the control system. |
