Abstract
The present disclosure is directed to a cardiac reinforcement device (CRD) and method for the treatment of cardiomyopathy. The CRD provides for reinforcement of the walls of the heart by constraining cardiac expansion, beyond a predetermined limit, during diastolic expansion of the heart. A CRD of the invention can be applied to the epicardium of the heart to locally constrain expansion of the cardiac wall or to circumferentially constrain the cardiac wall during cardiac expansion.
Claims27
A cardiac reinforcement device, said device comprising:
- a biomedical material which can be applied to the epicardial surface of the heart and which
- expands to a predetermined size, said predetermined size selected to constrain cardiac expansion beyond a predetermined limit.
A method for treating cardiac disease, said method comprising:
- (a) selecting a cardiac reinforcement device, said cardiac reinforcement device comprising:
- (i) a biomedical material which can be applied to the epicardial surface of the heart and which expands to a predetermined size, said predetermined size selected to constrain cardiac expansion beyond a predetermined limit;
- (b) applying said cardiac reinforcement device to the epicardial surface of the heart;
- and
- (c) securing said cardiac reinforcement device to said epicardial surface of the heart.
A method for reducing the diastolic volume of the heart, said method comprising:
- (a) selecting a cardiac reinforcement device, said cardiac reinforcement device comprising:
- (i) a biomedical material which can be applied to the epicardial surface of the heart and which expands to a predetermined size, said predetermined size selected to constrain cardiac expansion beyond a predetermined limit;
- (b) applying said cardiac reinforcement device to the epicardial surface of the heart;
- and
- (c) securing said cardiac reinforcement device to said epicardial surface of the heart.
