Abstract

Abstract The device and method for reducing heart wall stress. The device can be one which reduces wall stress throughout the cardiac cycle or only a portion of the cardiac cycle. The device can be configured to begin to engage, to reduce wall stress during diastolic filling, or begin to engage to reduce wall stress during systolic contraction. Furthermore, the device can be configured to include at least two elements, one of which engages full cycle and the other which engages only during a portion of the cardiac cycle.

Claims Analysis

Total Claims: 11

Claim 1

Independent Claim 42 words

1 . A device for reducing heart wall stress, comprising: a first means for reducing heart wall stress which engages throughout the cardiac cycle; and second means for reducing heart wall stress which begins to engage the heart wall during diastolic filling.

Claim 2

Dependent Claim 42 words

Claim 3

Dependent Claim 64 words

2 . The device in accordance with claim 1 , wherein the first means includes a splint having an elongate tension member, the elongate tension member having a first end and a second end, the splint having a first anchor member connected at the first end of the tension member and a second anchor member connected at the second end of the tension member.

Claim 4

Dependent Claim 64 words

3 . The device in accordance with claim 1 , wherein the second means includes a splint having an elongate tension member, the elongate tension member having a first end and a second end, the splint having a first anchor member connected at the first end of the tension member and a second anchor member connected at the second end of the tension member.

Claim 5

Dependent Claim 37 words

4 . The device in accordance with claim 1 , wherein the second means includes an elongate member sized to surround the heart and begin to engage a portion of the left ventricle wall during diastolic filling.

Claim 6

Dependent Claim 30 words

5 . The device in accordance with claim 1 , wherein the first means includes a frame including at least two means for engaging the wall of the left ventricle.

Claim 7

Dependent Claim 17 words

6 . The device in accordance with claim 5 , wherein the means for engaging include pads.

Claim 8

Dependent Claim 28 words

7 . The device in accordance with claim 5 , wherein the second means for reducing heart wall stress includes a means for engaging connected to the frame.

Claim 9

Dependent Claim 22 words

8 . The device in accordance with claim 7 , wherein the means for engaging of the second means includes a pad.

Claim 10

Dependent Claim 86 words

9 . A method of reducing heart wall stress, comprising the steps of: providing a device having at least one heart engaging member; placing the heart engaging member on the heart such that the shape of a cross section of the left ventricle is changed throughout the cardiac cycle; providing a second device having at least one heart engaging member; and placing the heart engaging member of the second device on the heart such that a second device begins to engage the heart during diastolic filling.
