Abstract
Abstract A stent for insertion into a heart wall for Trans Myocardial Revascularization (TMR) thereof. The TMR stent provides for the delivery of blood nutrients from a heart chamber into the heart wall and has an elongated body which may contain a cavity and openings through the elongated body from the cavity. The elongated body should be in fluid communication with the heart chamber. If a cavity and openings are provided, the openings are in fluid communication with the heart chamber, the cavity and the heart wall. The TMR stent may include an anchoring element integrally formed thereon for securing the TMR stent in the heart wall.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
61 words
A method for performing trans myocardial revascularization (TMR), comprising the steps of: a. identifying a portion of a heart wall that is targeted for treatment by TMR; b. obtaining access to the targeted portion of the heart wall; and c. inserting a TMR device into the targeted portion of the heart wall to aid in the formation of new blood vessels.
Claim 2
Independent Claim
61 words
A method for performing trans myocardial revascularization (TMR), comprising the steps of: a. identifying a portion of a heart wall that is targeted for treatment by TMR; b. obtaining access to the targeted portion of the heart wall; and c. inserting a TMR device into the targeted portion of the heart wall to aid in the formation of new blood vessels.
Claim 3
Dependent Claim
27 words
The method of claim 1, including the further step of creating a channel in the portion of the heart wall that is targeted for treatment by TMR.
Claim 4
Dependent Claim
15 words
The method of claim 2 wherein the created channel goes partially through the heart wall.
Claim 5
Dependent Claim
15 words
The method of claim 2 wherein the created channel goes entirely through the heart wall.
Claim 6
Independent Claim
88 words
A method for the placement in a heart wall of a suitable trans myocardial revascularization (TMR) device to aid in the formation of new blood vessels, comprising the steps of: a. identifying a portion of the heart wall that is targeted for treatment by the TMR device; b. obtaining access to the targeted portion of the heart wall; c. forming a channel in the targeted portion of the heart wall; and d. inserting the TMR device into the channel formed in the targeted portion of the heart wall.
Claim 7
Independent Claim
88 words
A method for the placement in a heart wall of a suitable trans myocardial revascularization (TMR) device to aid in the formation of new blood vessels, comprising the steps of: a. identifying a portion of the heart wall that is targeted for treatment by the TMR device; b. obtaining access to the targeted portion of the heart wall; c. forming a channel in the targeted portion of the heart wall; and d. inserting the TMR device into the channel formed in the targeted portion of the heart wall.

Claim 10
Dependent Claim
28 words
The method of claim 5, including the further step of inserting the TMR device into the channel in the targeted portion of the heart wall by mechanical means.
Claim 11
Dependent Claim
44 words
The method of claim 5, including the further step of spreading the channel in the targeted portion of heart wall by use of an obturator, to facilitate the insertion of the TMR device into the channel in the targeted portion of the heart wall.
Claim 12
Dependent Claim
35 words
The method of claim 5, including the further step of facilitating the insertion of the TMR device into the channel in the targeted portion of the heart wall, by using an expandable pre-stressed TMR device.
