Title:
POWER SYSTEM FOR A HEART ACTUATION DEVICE
Document Type and Number:
WIPO Patent Application WO2004110257
Kind Code:
A3
Abstract:
Actuator mechanisms on the heart are of several types. In preferred embodiments, they are generally simple, durable, mechanical assemblies and are driven by power delivered from a remote location, generally outside the chest, by a variety of mechanisms. The invention teaches physical mechanisms (1) for transfer of cyclic power from outside the chest to the region of the heart of that purpose, either as translational or rotary motion. Also taught are electromechanical converting mechanisms suitable for delivering power to those transfer devices. The embodiments described herein for either transmission of energy from a site of generation to a conduit (2, 10, 22) and of conduits that then deliver energy to heart actuators, have contours and interfaces designed to promote a favorable biologic response similar to the pseudosynovial capsules that surround artificial joints. Further, design features are chosen to avoid both non-vented gas-filled chambers and static collections of tissue fluid.
