Abstract
A catheter assembly for deployment in a vessel includes a catheter shaft extending from a proximal end portion to a distal end portion. A balloon is operatively coupled to the distal end portion of the catheter shaft. At least one cutting member is coupled to the catheter assembly. As the balloon is inflated, the cutting member is moved to a position to cut a portion of the vessel.
Claims20
A catheter assembly for deployment in a vessel, the assembly comprising:
- (a) a catheter shaft extending from a proximal end portion to a distal end portion;
- (b) a balloon operatively coupled to the distal end portion of the catheter shaft;
- and
- (c) a sheath positioned about the balloon, the sheath including at least one cutting member coupled thereto, wherein, as the balloon is inflated, the cutting member is moved to a position to cut a portion of the vessel.
A catheter assembly for deployment in a bifurcated vessel, the assembly comprising:
- (a) a catheter shaft extending from a proximal end portion to a distal end portion;
- (b) a balloon operatively coupled to the distal end portion of the catheter shaft;
- and
- (c) at least one cutting member coupled to the balloon, wherein, as the balloon is inflated, the cutting member is configured to be moved to a position to cut a portion of the bifurcated vessel.
A method for forming a catheter assembly for deployment in a bifurcated vessel, the method comprising:
- (a) providing a catheter shaft extending from a proximal end portion to a distal end portion;
- (b) coupling a balloon at the distal end portion of the catheter shaft;
- (c) positioning a cutting member relative to the balloon;
- and
- (d) inflating the balloon to move the cutting member towards a wall of a blood vessel to cut the wall.
