Abstract

A balloon catheter comprising a catheter tube, at least one inflatable balloon attached to the catheter tube and at least one narrowing device for narrowing the diameter of the at least one inflatable balloon at least at one portion.

Claims

1. A balloon catheter comprising:

a catheter tube;

at least one inflatable balloon attached to said catheter tube; and

at least one ring-like shaped narrowing device for narrowing the diameter of said at least one inflatable balloon at least at one portion thereof;

said narrowing device comprising a zig-zagged ring.

2. A balloon catheter according to claim 1 wherein said zig-zagged ring is capable of changing its diameter.

3. A method of fabricating a balloon catheter comprising the steps of providing a catheter tube;

providing an inflatable balloon having two ends;

attaching the two ends of the inflatable balloon to the catheter tube; and

placing said at least one zig-zagged shaped narrowing device on predetermined positions of said balloon; and

connecting at least one narrowing device to the balloon at predetermined positions between the attached ends of the inflatable balloon.

4. A method of deploying a stent in a desired location comprising the steps of:

providing a stent;

attaching said stent to a balloon catheter;

placing at least one zig-zagged shaped narrowing device on predetermined position of said balloon;

guiding said balloon catheter to a desired location;

inflating the balloon catheter is said location; and

detaching the stent from said balloon catheter,

wherein said stent and said balloon catheter are capable to shape in accordance with the shape of said location.

5. A method according to claim 4 wherein said location is in an arch like shape.

6. A method according to claim 4 wherein said location is generally not linear.
