Dual wire placement catheter
First Claim
1. A method of positioning a first wire through a portion of a first branch vessel, across a bifurcation of a main vessel and through a portion of a second branch vessel, and a second wire through the portion of the first branch vessel and into the main vessel, comprising the steps of:
- introducing a catheter through a first access site and into the first branch vessel, the catheter having at least first and second lumens;
advancing the catheter superiorly to the bifurcation of the main vessel and inferiorly down the second branch vessel to a second access site;
introducing a first wire through the first lumen and between the first access site and the second access site;
introducing a second wire through the second lumen superiorly through the first branch vessel and into the main vessel; and
removing the catheter, while leaving the first and second wires in place.

Abstract
Disclosed is a dual lumen access catheter, for facilitating placement of two procedure wires across a treatment site. In one application, the catheter is used to place a first wire extending between a contralateral iliac and an ipsilateral iliac across the terminal bifurcation of the aorta, and a second wire extending through a portion of the ipsilateral iliac and into the aorta. Methods of placing the wires, such as for subsequent deployment of an abdominal aortic aneurysm bifurcation graft, are also disclosed.

10. A method of positioning a first wire through a portion of a first branch vessel that branches from a main vessel, across a branching of the main vessel and through a portion of a second branch vessel, and a second wire through the portion of the first branch vessel and into the main vessel, comprising the steps of:
-
introducing a catheter through a first access site and into the first branch vessel, the catheter having at least first and second lumens;
advancing the catheter superiorly to the bifurcation of the main vessel and inferiorly down the second branch vessel to a second access site;
introducing a first wire through the first lumen and between the first access site and the second access site;
introducing a second wire through the second lumen superiorly through the first branch vessel and into the main vessel; and
removing the catheter, while leaving the first and second wires in place. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method of transluminally deploying a bifurcation graft at the bifurcation of a main vessel into a first branch vessel and a second branch vessel;
- comprising the steps of;
introducing a catheter through a first access site and into the first branch vessel, the catheter having at least first and second lumens;
advancing the catheter superiorly to the bifurcation of the main vessel and inferiorly down the second branch vessel to a second access site;
introducing a first wire through the first lumen from the first access site through the second access site;
introducing a second wire through the second lumen from the first access site superiorly through the first branch vessel and into the aorta;
removing the catheter, while leaving the first and second wires in place; and
deploying a bifurcation graft at the bifurcation of the main vessel into the first and second branch vessels. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)
