Method and apparatus for treating stenoses at bifurcated regions
First Claim
1. An apparatus for treating a bifurcated region of a body lumen, comprising:
- a catheter having a proximal end and a distal end;
first and second expandable portions at the distal end of said catheter; and
means distal of said first and second expandable portions for linking said first and second expandable portions to one another.

Abstract
A method and apparatus for treating stenoses at bifurcated regions of body lumens is disclosed. A balloon catheter system is disclosed comprising two balloon catheters, or a balloon catheter having a bifurcated distal end, with a linking guide wire lumen at the distal end of one balloon catheter, or one branch of the bifurcated catheter, for linking the two balloons or branches such that the device can be tracked to a treatment site. Once at the treatment site, the balloon catheters or branches of the bifurcated distal end can be unlinked and separately positioned within the branches of the bifurcated body lumen. The apparatus can also serve as a delivery system for multiple prostheses or a bifurcated endoluminal prosthesis.

18. A method for treating a bifurcation region of a body lumen using a catheter system comprising a proximal and a distal end, said distal end having first and second expandable portions and a distal tip structure, the bifurcation region having at least a first and second branch, said method comprising the steps of:
-
accessing a body lumen; placing a first guide wire in the body lumen and into the second branch of said bifurcation region; threading the first guide wire through the distal tip structure; advancing the catheter system over the first guide wire such that the distal tip structure is proximate the second branch of the bifurcation region; positioning the first and second expandable portions of the catheter system in the first and second branches of said bifurcation region; expanding said first and second expandable portions thereby treating the bifurcation region; and withdrawing said catheter system from the body lumen. - View Dependent Claims (19, 20, 21)

22. A method for treating a bifurcation region of a body lumen using a catheter system comprising a proximal and a distal end, said distal end having first and second expandable portions and a distal tip structure, said first and second expandable portions comprising first and second guide wire lumens, respectively, said distal tip structure comprising a distal portion of the second guide wire lumen and a housing for releasably retaining a guide wire, the bifurcation region having at least a first and second branch, said method comprising the steps of:
-
accessing a body lumen; placing a first guide wire in the body lumen and into the second branch of said bifurcation region; threading a second guide wire through the second guide wire lumen and into the housing for releasably retaining the guide wire; threading the first guide wire through the distal tip structure; advancing the catheter system over the first guide wire such that the distal tip structure is proximate the second branch of the bifurcation region; withdrawing the second guide wire from the housing; positioning the first and second expandable portions of the catheter system in the first and second branches of said bifurcation region; expanding said first and second expandable portions thereby treating the bifurcation region; and withdrawing said catheter system from the body lumen. - View Dependent Claims (23, 24)
