Abstract
Abstract A method of treating arterial disease at the intersection of two arteries using both a graft and stent. The graft is placed at the intersection of two arteries by the use of a balloon catheter. A device is used to make an opening in the graft at a point corresponding to the intersection of the two arteries. A stent is inserted into the graft and through the graft opening; the stent having an attachment mechanism to attach one end of the stent to the opening in the graft whereby the flow of blood at the intersection of the arteries is ensured.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
141 words
A method for treating arterial disease at an intersection of two arteries, using a graft and stent, comprising the steps of: providing a graft adapted to be inserted into an artery to be treated; inserting said graft using a balloon catheter in positioning said graft to a point of intersection of two arteries to be treated; identifying a point within said graft located at the intersection of the arteries to be treated; manufacturing an opening in said graft at the point of said intersection of said arteries to be treated; inserting a stent through said opening thereby creating a pathway between said arteries to be treated; affixing said stent to said graft at the opening; whereby the cooperation of the graft and stent inserted through the opening ensures the flow of blood at the intersection of the arteries to be treated.
Claim 2
Independent Claim
141 words
A method for treating arterial disease at an intersection of two arteries, using a graft and stent, comprising the steps of: providing a graft adapted to be inserted into an artery to be treated; inserting said graft using a balloon catheter in positioning said graft to a point of intersection of two arteries to be treated; identifying a point within said graft located at the intersection of the arteries to be treated; manufacturing an opening in said graft at the point of said intersection of said arteries to be treated; inserting a stent through said opening thereby creating a pathway between said arteries to be treated; affixing said stent to said graft at the opening; whereby the cooperation of the graft and stent inserted through the opening ensures the flow of blood at the intersection of the arteries to be treated.
Claim 3
Dependent Claim
17 words
The method according to claim 1 wherein said identifying step is accomplished using an intravenous ultrasound system.
Claim 4
Dependent Claim
16 words

Claim 7
Dependent Claim
28 words
The method according to claim 1 wherein said affixing step comprises the use of a collar having a plurality of tines interposed on the diameter of said stent.
Claim 8
Dependent Claim
13 words
The method according to claim 1 wherein said stent is frusto-conical in shape.
Claim 9
Dependent Claim
13 words
The method according to claim 1 wherein said stent is cylindrical in shape.
