Abstract

An actuation system for assisting the operation of a natural heart is disclosed. The actuation system includes a framework (61) for interfacing with the natural heart and a power system (10) that can be coupled to the framework. The framework (61) includes an internal framework element and an external framework (30) element. The power system (10) is configured to engage an exterior surface of the heart wall, and includes an actuator mechanism (22) for exerting force on the heart wall, a driving mechanism (24) for actuating the actuator mechanism (22), a transmission mechanism (32) coupled between the actuator mechanism and the driving mechanism (24) for transmitting power to the actuator mechanism (22), and a carrier device coupled between the actuator mechanism (22) and the driving mechanism (24) and configured for housing the transmission mechanism (32). The modular power system (10) is configured for being freely exchanged and replaced in the actuation system while leaving the framework elements in place and generally undisturbed. A guide structure (28) such as a wire or tube can also be included for guiding or advancing the power system (10) to its position adjacent to the heart surface.
