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.
Claims20
A multilumen catheter, comprising:
- an elongate, flexible tubular body, having a proximal end and a distal end;
- a first lumen extending throughout the length of the tubular body, between the proximal end and the distal end;
- and
- a second lumen extending between a proximal port and a distal port;
- wherein at least the distal port is spaced proximally apart from the distal end.
A method of positioning a first wire through a portion of the ipsilateral iliac, across the bifurcation of the aorta and through a portion of the contralateral iliac, and a second wire through the portion of the ipsilateral iliac and into the aorta, comprising the steps of:
- introducing a catheter through a first access site and into a first iliac, the catheter having at least first and second lumens;
- advancing the catheter superiorly to the bifurcation of the aorta and inferiorly down a second iliac 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 ipsilateral iliac and into the aorta;
- and
- removing the catheter, while leaving the first and second wires in place.
A method of transluminally deploying a bifurcation graft at the bifurcation of the aorta into the ipsilateral and contralateral iliacs, comprising the steps of:
- introducing a catheter through a first access site and into the ipsilateral iliac, the catheter having at least first and second lumens;
- advancing the catheter superiorly to the bifurcation of the aorta and inferiorly down the contralateral iliac 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 ipsilateral iliac and into the aorta;
- and
- removing the catheter, while leaving the first and second wires in place.
A method of transluminally deploying a bifurcation graft at the bifurcation of the aorta into the ipsilateral and contralateral iliacs, comprising the steps of:
- introducing a catheter through a first access site and into the contralateral iliac, the catheter having at least first and second lumens;
- advancing the catheter superiorly to the bifurcation of the aorta and inferiorly down the ipsilateral iliac to a second access site;
- introducing a first wire through the first lumen between the first access site and the second access site;
- introducing a second wire through the second lumen from the second access site superiorly through the ipsilateral iliac and into the aorta;
- and
- removing the catheter, while leaving the first and second wires in place.
