Fully implantable direct myocardium assist device

Abstract

The present invention provides an implantable cardiac compression device comprising: an inflatable cardiac compression jacket configured when inflated to directly compress a heart and assist in displacing blood therefrom, a channel that connects the inflatable cardiac compression jacket and an expandable fluid reservoir configured to contain a fluid when displaced compresses the inflatable cardiac compression jacket, and a fluid driver operably connected to the inflatable cardiac compression jacket and to the expandable fluid reservoir, wherein the fluid driver is configured to inflate the cardiac compression jacket and to deflate the expandable fluid reservoir during systole of the heart; said driver is further configured to deflate the cardiac compression jacket and to inflate the expandable fluid reservoir during diastole of the heart.
