Abstract
The invention herein is directed to a dilatation catheter comprising a steering wire, a dilatation balloon encompassing the said steering wire, and a flexible, inflatable catheter shaft concentric to the steering wire and in fluid communication with the balloon.
Claims15
A dilatation catheter comprising:
- a steering wire;
- a dilatation balloon longitudinally encompassing said steering wire;
- and
- a flexible catheter shaft eccentric to the steering wire and in fluid communication with the balloon, wherein the catheter shaft can be inflated to increase the diameter of the catheter shaft to a predetermined size and the diameter of the catheter shaft decreases when the catheter shaft is deflated.
1 more element
A dilatation catheter comprising:
- a steering wire;
- a dilatation balloon longitudinally encompassing said steering wire;
- and
- a flexible catheter shaft eccentric to the steering wire and having proximal and distal ends, the distal end of the catheter shaft being in fluid communication with the balloon, such that the catheter shaft is inflatable to increase the diameter of the catheter shaft to a predetermined size, and the diameter of the catheter shaft decreases when the catheter shaft is deflated.
1 more element
A dilatation catheter comprising:
- a first catheter shaft having a longitudinally extending first lumen containing a steering wire and having proximal and distal ends;
- a dilatation balloon at the distal end of the catheter shaft;
- a second flexible catheter shaft having a second lumen adjacent and parallel to said first lumen and in fluid communication with the inner surface of said balloon, such that the catheter shaft is inflatable to increase the diameter of the catheter shaft to a predetermined size, and the diameter of the catheter shaft decreases when the catheter shaft is deflated.
