Abstract

A catheter including at least one inflatable chamber disposed on a catheter stem and in fluid communication with at least one inflation lumen in the catheter stem, the at least one inflatable chamber including an expandable covering with an underfold fluidly sealed to the catheter stem, the underfold including a portion of the expandable covering that is folded underneath itself.

Claims

1. A catheter comprising:

at least one inflatable chamber disposed on a catheter stem and in fluid communication with at least one inflation lumen in said catheter stem, said at least one inflatable chamber comprising an expandable covering with an underfold fluidly sealed to said catheter stem, said underfold comprising a portion of the expandable covering that is folded underneath itself.

2. The catheter according to claim 1, comprising at least two of said inflatable chambers disposed longitudinally along said catheter stem.

3. The catheter according to claim 2, wherein said inflatable chambers abut one another in an inflated state.

4. The catheter according to claim 2, wherein said catheter stem comprises at least one lateral exit disposed between said at least two inflatable chambers.

5. The catheter according to claim 1, further comprising another inflatable chamber disposed on said catheter stem.

6. The catheter according to claim 5, wherein said other inflatable chamber shares a common seal with said at least one inflatable chamber, said seal fluidly sealing them to said catheter stem.

7. The catheter according to claim 4, further comprising a first guide wire disposed within said catheter stem.

8. The catheter according to claim 4, further comprising a second guide wire adapted to exit the catheter stem through said at least one lateral exit.

9. The catheter according to claim 1, further comprising a deformable stent positioned coaxially around the inflatable chambers and adapted to radially deform upon application of an expansive force.

10. The catheter according to claim 9, wherein said deformable stent comprises a deformable side aperture.
