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: 9
Claim 1
Independent Claim
110 words
An apparatus for placement on a heart of a patient to treat a heart condition characterized at least in part by diastolic expansion of a size of the heart, the apparatus comprising: a flexible and compliant, biomedical material formed in a jacket having an internal volume and an opening exposing said internal volume; said jacket sized for jacket to be placed over said heart with an apex of said heart passed through said opening and with at least a ventricular portion of said heart received within said volume, said jacket further sized to present a resistance to diastolic expansion; said material of said jacket including at least a shape-memory material.
Claim 2
Independent Claim
110 words
An apparatus for placement on a heart of a patient to treat a heart condition characterized at least in part by diastolic expansion of a size of the heart, the apparatus comprising: a flexible and compliant, biomedical material formed in a jacket having an internal volume and an opening exposing said internal volume; said jacket sized for jacket to be placed over said heart with an apex of said heart passed through said opening and with at least a ventricular portion of said heart received within said volume, said jacket further sized to present a resistance to diastolic expansion; said material of said jacket including at least a shape-memory material.
Claim 3
Dependent Claim
11 words
An apparatus according to claim 1 wherein said material is elastic.
Claim 4
Dependent Claim
19 words
An apparatus according to claim 1 wherein said jacket is sized to constrain diastolic expansion beyond a predetermined limit.
Claim 5
Dependent Claim
27 words
An apparatus according to claim 1 wherein said material is formed in an open cell construction with a plurality of open cells defined by interconnected, elongated elements.
Claim 6
Dependent Claim
20 words
An apparatus according to claim 1 wherein said jacket is sized to be applied to the epicardium of the heart.
Claim 7
Dependent Claim
20 words
An apparatus according to claim 1 wherein said jacket is sized to be applied to the pericardium of the heart.
Claim 8
Dependent Claim
22 words
An apparatus according to claim 1 wherein said shape memory material is disposed at least circumferentially around a base of said jacket.
Claim 9
Dependent Claim
22 words
An apparatus according to claim 1 wherein said shape memory material is disposed to reduce a size of said jacket following placement.
