Abstract
Abstract A method for placing a splint assembly transverse a heart chamber includes providing an elongate member having a first end and a second end and a deployable heart-engaging assembly connected to at least the first end. The method includes advancing the elongate member through vasculature structure and into the heart chamber such that the first end of the elongate member extends through a first location of a wall surrounding the heart chamber and the second end extends through a second location of the heart chamber wall substantially opposite the first location. A deployable heart-engaging assembly is deployed such that it engages with a first exterior surface portion of the heart chamber wall adjacent the first location. The elongate member is secured with respect to the heart with a second heart-engaging assembly connected to the second end. The second heart-engaging assembly engages with a second exterior surface portion of the heart chamber wall adjacent the second location. A splint assembly includes an expandable heart-engaging assembly formed partially from portions forming the elongate member of the splint assembly. A delivery tool includes a tubular member configured to be advanced through vasculature structure and has a curved distal end.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
149 words
A method for placing a splint assembly transverse a heart chamber, the method comprising: providing an elongate member having a first end and a second end and a deployable heart-engaging assembly connected to said first end; advancing the elongate member through vasculature structure and into the heart chamber such that the first end of the elongate member extends through a first location of a heart chamber wall and the second end extends through a second location of a heart chamber wall substantially opposite the first location; deploying the deployable heart-engaging assembly such that it engages with a first exterior surface of a heart chamber wall adjacent the first location; and securing the elongate member with respect to the heart chamber with a second heart-engaging assembly connected to the second end, said second heart-engaging assembly engaging with a second exterior surface of a heart chamber wall adjacent the second location.
Claim 2
Independent Claim
149 words
A method for placing a splint assembly transverse a heart chamber, the method comprising: providing an elongate member having a first end and a second end and a deployable heart-engaging assembly connected to said first end; advancing the elongate member through vasculature structure and into the heart chamber such that the first end of the elongate member extends through a first location of a heart chamber wall and the second end extends through a second location of a heart chamber wall substantially opposite the first location; deploying the deployable heart-engaging assembly such that it engages with a first exterior surface of a heart chamber wall adjacent the first location; and securing the elongate member with respect to the heart chamber with a second heart-engaging assembly connected to the second end, said second heart-engaging assembly engaging with a second exterior surface of a heart chamber wall adjacent the second location.
Claim 3
Dependent Claim
16 words
The method of claim 1 , wherein the chamber is a left ventricle of the heart.
Claim 4
Dependent Claim
22 words
The method of claim 2 , wherein the elongate member is advanced through a guide device endovascularly inserted into the right ventricle.
Claim 5
Dependent Claim
13 words
The method of claim 3 , wherein the guide device is a catheter.
Claim 6
Dependent Claim
45 words
The method of claim 3 , wherein inserting the guide device includes extending the guide device across the left ventricle from the right ventricle through the first location on a free wall surrounding the left ventricle and through the second location on a septal wall.
Claim 7
Dependent Claim
22 words
The method of claim 3 , wherein inserting the guide device includes stabilizing the guide device with respect to the left ventricle.
Claim 8
Dependent Claim
21 words
The method of claim 6 , wherein the stabilizing includes inflating balloons disposed proximate a distal end of the guide device.
Claim 9
Dependent Claim
37 words
The method of claim 7 , wherein the stabilizing includes inflating a first balloon adjacent the first exterior surface of the heart chamber wall and a second balloon adjacent an interior surface of the heart chamber wall.
Claim 10
Dependent Claim
24 words
The method of claim 2 , wherein the inserting includes inserting a guide device into the left ventricle without first entering another heart chamber.
Claim 11
