Abstract

A stent delivery system comprising a catheter having an inner tube and an outer tube surrounding the inner tube; a balloon having a proximal end fixed to the outer tube a distal end fixed to the inner tube and an interior including a proximal portion and distal portion, a stent disposed on the balloon and being expandable from a delivery position to a deployed position by a contrast medium adapted to be supplied to the interior of the balloon, and a contrast medium distribution means disposed in the interior of the balloon adapted to equally distribute the contrast medium to both the proximal portion and the distal portion of the interior of the balloon.

Claims

1. A stent delivery system comprising:

a catheter having;

an inner tube; and

an outer tube surrounding the inner tube;

a balloon having;

a proximal end fixed to the outer tube,

a distal end fixed to the inner tube and

an interior including a proximal portion and distal portion;

a stent disposed on the balloon and being expandable from a delivery position to a deployed position by a contrast medium adapted to be supplied to the interior of said balloon, and

a contrast medium distribution means disposed in the interior of the balloon adapted to equally distribute the contrast medium to both the proximal portion and the distal portion of the interior of the balloon.

2. The stent delivery system of claim 1, wherein the contrast medium distribution means is the outer tube extended to the middle of the interior of said balloon.

3. The stent delivery system of claim 1, wherein the contrast medium distribution means is the outer tube extended to the distal portion of said balloon.

4. The stent delivery system of claim 1, wherein the outer tube comprises proximal and distal distribution holes.

5. The stent delivery system of claim 1 wherein the contrast medium distribution means is a profiled tube between markers on the inner tube.

6. The stent delivery system of claim 1 wherein the contrast medium distribution means is a spiral tube on the inner tube.

7. The stent delivery system of claim 6 wherein the spiral tube is configured so to constitute as the markers.

8. A stent delivery system comprising:

a catheter having;

an inner tube; and

an outer tube surrounding the inner tube;

a balloon having;

a proximal end fixed to the outer tube;

a distal end fixed to the inner tube; and

an interior including a proximal portion and distal portion;

a stent disposed on the balloon and being expandable from a delivery position to a deployed position by a contrast medium adapted to be supplied to the interior of said balloon, and

a spiral tube on the inner tube disposed in the interior of the balloon adapted to equally distribute the contrast medium to both the proximal portion and the distal portion of the interior of the balloon, wherein the spiral tube is configured so to constitute as the markers.
