Abstract
Abstract A method and implantation tools for placing a transventricular splint including a tension member. The method includes gaining access to the patient's hearts and identifying entry or exit points for the tension member, marking those locations and delivering the tension member. Anchors for the tension member are also delivered. The length of the tensions member is measured and the walls of the heart drawn together. The pads are secured to the tension member and the tension member is trimmed to length. The pads are secured to the heart surface.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
64 words
A method for determining locations on a heart wall to position a splint relative to a heart, comprising: indenting the heart wall in locations corresponding to a potential position of a splint relative to the heart; viewing indentations created by the indenting relative to internal structures of the heart; and determining whether positioning the splint at the indentations will interact with the internal structures.
Claim 2
Independent Claim
64 words
A method for determining locations on a heart wall to position a splint relative to a heart, comprising: indenting the heart wall in locations corresponding to a potential position of a splint relative to the heart; viewing indentations created by the indenting relative to internal structures of the heart; and determining whether positioning the splint at the indentations will interact with the internal structures.
Claim 3
Dependent Claim
25 words
The method of claim 1 , further comprising placing the splint at the indentations if the interaction with the internal structures produces a desired effect.
Claim 4
Dependent Claim
17 words
The method of claim 1 , wherein viewing the indentations includes viewing the indentations using ultrasonic imaging.
Claim 5
Dependent Claim
35 words
The method of claim 1 , wherein indenting the heart wall includes indenting the heart wall with a member positioned with respect to the heart wall such that it causes the heart wall to indent.
Claim 6
Dependent Claim
21 words
The method of claim 4 , wherein viewing the indentations created by the member includes viewing the indentations using ultrasonic imaging.
Claim 7
Dependent Claim
16 words
The method of claim 4 , wherein the member is made of fluroscopic-visible or echo-visible material.
Claim 8
Independent Claim
86 words
A method for determining locations on a heart wall to position a tension member transverse a heart chamber, comprising the steps of: providing a locating member adapted to be viewed from an exterior of said heart chamber; positioning said locating member at first and second locations on said heart wall; and viewing said locating member relative to internal structures of the heart chamber to determine whether a tension member positioned across said chamber from the first location to the second location would damage the internal structures.
Claim 9
Independent Claim
86 words
A method for determining locations on a heart wall to position a tension member transverse a heart chamber, comprising the steps of: providing a locating member adapted to be viewed from an exterior of said heart chamber; positioning said locating member at first and second locations on said heart wall; and viewing said locating member relative to internal structures of the heart chamber to determine whether a tension member positioned across said chamber from the first location to the second location would damage the internal structures.
Claim 10
Dependent Claim
21 words
The method of claim 7 , wherein said providing step includes providing a locating member comprised of fluoroscopic-visible or echo-visible material.
Claim 11
Independent Claim
15 words
The method of 8 , wherein said viewing step includes viewing by fluoroscopy or echo-imaging.
Claim 12
Independent Claim
15 words
The method of 8 , wherein said viewing step includes viewing by fluoroscopy or echo-imaging.
Claim 13
Dependent Claim
20 words
The method of claim 7 , wherein said positioning step includes positioning said locating member external to the heart chamber.
Claim 14
Dependent Claim
29 words
The method of claim 7 , wherein said providing step includes providing two locating members and said positioning step includes positioning said locating members external to said heart chamber.
Claim 15
Dependent Claim
22 words
The method of claim 7 , wherein said positioning step includes positioning said locating member on an interior of said heart chamber.
Claim 16
Dependent Claim
16 words
The method of claim 7 , wherein the providing step includes providing an inflatable locating member.
