ABSTRACT:
A unified system for implantation in the thorax and for cannulation to the blood circulatory system comprises an electronic controller for generating an actuating signal and an energy convertor for converting the actuating signal into a back and forth rhythmic displacement of the blood between a blood pumping chamber (BPC) and a volume displacement chamber (VDC). The BPC has an inflow port and an outflow port and converts the back and forth displacement into a rhythmic unidirectional displacement of blood from the inflow to the outflow port. The actuating signal is generated by a detector in response to the status of the BPC. A support unitary with the VDC supports the internal electronic controller, the actuating means, the BPC, and the detecting means in a compact structure and has a surface curvature compatible with the internal human sagittal and transverse chest wall curvatures. The BPC is arranged with the inflow and outflow ports oriented away from the support for ready cannulation to the circulatory system.
