Abstract:
1. An implantable, sub-cutaneous, bellows-like device with one plate proximal (or superficial) to the skin surface and the other plate distal (or deep) to the skin surface comprising: an implantable internal pneumatic/hydraulic driver for an implantable medical device such as a cardiac assist, cardiac support, or combined cardiac assist and support device wherein the implantable pneumatic/hydraulic internal driver comprises a distal plate comprising an inducible magnet material; a proximal plate separated from the distal plate by one or more bellows; a fluid within the one or more bellows; and a fluid connection to connect the implantable pneumatic/hydraulic internal driver to the implantable medical device wherein the distal plate can be magnetically drawn towards the proximal plate by the action of an external magnet outside the body to contract the bellows to pressurize the fluid in the bellows to allow the fluid to drive the implantable medical device.
