US 2014/0194985 A1 · CONTROLLER AND POWER SOURCE FOR IMPLANTABLE BLOOD PUMP

Abstract

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 for driving an implantable pump is provided. The digital processor is responsive to data associated with the operation of the pump received at the data transfer port, and from the program data stored in memory, (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 with a strain relief segment, and a lower housing portion that is heavier than an upper housing portion, may also be provided with the control system.

Dependent claims

A control system for driving an implantable blood pump comprising:

a first housing including electronic components configured to drive the pump;
and
a second housing including a battery;
wherein the first housing includes a first latch member extending from the first housing on a first side of the first housing and first and second recesses on a second side of the first housing;
wherein the second housing includes a third recess on a first side of the second housing and second and third latch members extending from the second housing on a second side of the second housing;
wherein when the first side of the first housing is aligned with the first side of the second housing, the first latch member aligns with the third recess, the second latch member aligns with the first recess, and the third latch member aligns with the second recess.
