Abstract
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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
100 words
A method for treating a myocardial infarction of a heart wall, the heart wall having an epicardial surface wall, said method comprising: (a) selecting a cardiac reinforcement device, said device comprising a biomedical material having a predetermined size, wherein said device is configured to cover at least an area of the epicardial surface of the heart to provide constraint of the heart wall; (b) applying said cardiac reinforcement device to the heart, wherein said device covers at least at an area that has been damaged due to the myocardial infarction; and (c) securing said cardiac reinforcement device to the heart.
Claim 2
Independent Claim
100 words
A method for treating a myocardial infarction of a heart wall, the heart wall having an epicardial surface wall, said method comprising: (a) selecting a cardiac reinforcement device, said device comprising a biomedical material having a predetermined size, wherein said device is configured to cover at least an area of the epicardial surface of the heart to provide constraint of the heart wall; (b) applying said cardiac reinforcement device to the heart, wherein said device covers at least at an area that has been damaged due to the myocardial infarction; and (c) securing said cardiac reinforcement device to the heart.
Claim 3
Dependent Claim
17 words
The method according to claim 1 , wherein said cardiac reinforcement device is configured as a patch.
Claim 4
Dependent Claim
26 words
The method according to claim 2 , wherein said patch is applied to the epicardial surface of the heart over a parietal pericardium of the heart.
Claim 5
Dependent Claim
26 words

Claim 13
Dependent Claim
20 words
The method according to claim 11 , wherein the mesh is selected from a propylene mesh and a polyester mesh.
Claim 14
Dependent Claim
15 words
The method according to claim 1 , wherein the biomedical material comprises a non-perforate material.
Claim 15
Dependent Claim
13 words
