Claims Analysis
Total Claims: 30
Claim 1
Independent Claim
121 words
A device for treating a heart, comprising: a first heart-engaging surface; a second heart-engaging surface substantially opposite to the first heart-engaging surface, said first and second heart-engaging surfaces being configured to contact a heart wall to passively alter a shape of the heart during a cardiac cycle, wherein all of a surface area of each of the heart engaging surfaces is configured to be stabilized with respect to the heart wall; an interconnecting member for connecting the first and second heart-engaging surfaces and configured to extend around an exterior portion of the heart; and an adjusting mechanism operably connected to at least one of the first and second heart-engaging surfaces for adjusting a distance between the first and second heart-engaging surfaces.
Claim 2
Independent Claim
121 words
A device for treating a heart, comprising: a first heart-engaging surface; a second heart-engaging surface substantially opposite to the first heart-engaging surface, said first and second heart-engaging surfaces being configured to contact a heart wall to passively alter a shape of the heart during a cardiac cycle, wherein all of a surface area of each of the heart engaging surfaces is configured to be stabilized with respect to the heart wall; an interconnecting member for connecting the first and second heart-engaging surfaces and configured to extend around an exterior portion of the heart; and an adjusting mechanism operably connected to at least one of the first and second heart-engaging surfaces for adjusting a distance between the first and second heart-engaging surfaces.

Claim 22
Independent Claim
100 words
A method of treating a heart, comprising the steps of: providing a member having at least two heart-engaging surfaces, wherein all of a surface area of each of the heart engaging surfaces is configured to be stabilized with respect to the heart wall; positioning said member around at least a portion of an exterior of a heart chamber such that said heart-engaging surfaces are positioned on an exterior of said heart; and adjusting a distance between said at least two heart-engaging surfaces after positioning the member so that a shape of said chamber is passively altered during a cardiac cycle.
Claim 23
Independent Claim
100 words
A method of treating a heart, comprising the steps of: providing a member having at least two heart-engaging surfaces, wherein all of a surface area of each of the heart engaging surfaces is configured to be stabilized with respect to the heart wall; positioning said member around at least a portion of an exterior of a heart chamber such that said heart-engaging surfaces are positioned on an exterior of said heart; and adjusting a distance between said at least two heart-engaging surfaces after positioning the member so that a shape of said chamber is passively altered during a cardiac cycle.
