Abstract
The present invention provides a biphasic and dynamic direct cardiac contact device adapted to be implanted in a patient suffering from congestive heart failure and related cardiac pathologies, said cardiac device having means for providing ventricular assist, ventricular support and diastolic recoil, or for providing ventricular support and diastolic recoil only.
Claims33
A biphasic direct cardiac contact device adapted to be implanted in a patient suffering from congestive heart failure and related cardiac pathologies, said cardiac device comprising:
- an adjustable passive support component in contact with an epicardial surface of the heart to continually apply support to the heart, wherein said adjustable passive support component constrains ventricle filling when the cardiac volume exceeds the target end diastolic volume;
- and
- an elastic memory component in contact with the adjustable passive support component wherein the elastic memory component creates a negative pressure that promotes ventricle filling when a cardiac volume is lower than a target end diastolic volume,
- wherein the biphasic direct cardiac contact device can separately modulate the end systolic and end diastolic configurations of the heart.
