Abstract

Abstract A method and a device for improving cardiac function are provided. The device is packaged in a collapsed state in an end of a catheter. Portions of a frame construction of the device spring outwardly when the catheter is withdrawn from the device. Anchoring formations on the frame construction secure the frame construction to a myocardium of the heart. A membrane secured to the frame construction then forms a division between volumes of an endocardial cavity of the heart on opposing sides of the membrane.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 30 words
1 . A method, comprising: anchoring a device to a part of a myocardium defining a pressurized left ventricle of a heart, the device improving cardiac function of the heart.
Claim 2
Dependent Claim 30 words
1 . A method, comprising: anchoring a device to a part of a myocardium defining a pressurized left ventricle of a heart, the device improving cardiac function of the heart.
Claim 3
Dependent Claim 27 words
2 . The method of claim 1 , wherein at least a component of the device penetrates into the part of the myocardium defining the left ventricle.
Claim 4
Dependent Claim 15 words
3 . The method of claim 2 , wherein the component is an anchoring formation.
Claim 5
Dependent Claim 15 words
4 . The method of claim 3 , wherein the anchoring formation is a screw.
Claim 6
Dependent Claim 31 words
5 . The method of claim 3 , wherein the anchoring formation is an anchoring hook having a sharp end that penetrates the part of the myocardium defining the left ventricle.
Claim 7
Dependent Claim 28 words
6 . The method of claim 3 , wherein the anchoring formation is at least one of a pin, a clamp, a staple, a screw, and surgical thread.
Claim 8
Dependent Claim 19 words
7 . The method of claim 2 , wherein the component penetrates through only a portion of the myocardium.
Claim 9
Dependent Claim 27 words
8 . The method of claim 1 , wherein the component is anchored at two spaced locations to the part of the myocardium defining the left ventricle.
Claim 10
Dependent Claim 20 words
9 . The method of claim 1 , wherein the device is located adjacent an anterior wall of the heart.
Claim 11
Dependent Claim 15 words
10 . The method of claim 1 , wherein the myocardium forms an aneurysmic bulge.
Claim 12
Dependent Claim 14 words
11 . The method of claim 10 , wherein the aneurysmic bulge is ischaemic.
Claim 13
Dependent Claim 17 words
12 . The method of claim 1 , wherein the device increases cardiac output of the heart.
Claim 14
Dependent Claim 28 words
13 . The method of claim 1 , wherein the device decreases a degree to which the myocardium is stretched during a pump cycle of the left ventricle.
Claim 15
Dependent Claim 22 words
14 . The method of claim 1 , wherein the left ventricle sustains a peak left ventricular pressure above 60 mm Hg.
Claim 16
Dependent Claim 20 words
15 . The method of claim 14 , wherein the the peak left ventricular pressure is approximately 120 mm Hg.
Claim 17
Dependent Claim 63 words
16 . A method, comprising: locating a part of a device adjacent to a dyskinetic portion of a heart defining a left ventricle of the heart; and anchoring the device to a part of a myocardium of the heart defining the left ventricle while the part of the device is adjacent to the dyskinetic portion, the device improving cardiac function of the heart.
Claim 18
Dependent Claim 63 words
16 . A method, comprising: locating a part of a device adjacent to a dyskinetic portion of a heart defining a left ventricle of the heart; and anchoring the device to a part of a myocardium of the heart defining the left ventricle while the part of the device is adjacent to the dyskinetic portion, the device improving cardiac function of the heart.
Claim 19
Dependent Claim 21 words
17 . The method of claim 16 , wherein the part of the device is a central part of the device.
