Abstract
A balloon catheter and methods for use are disclosed for endovascular procedures, e.g., performing a thrombectomy. In one embodiment, among others, the balloon catheter includes an elongated catheter body. At a distal end, the catheter body also includes an angled tip and a balloon adjacent to the angled tip. The balloon is inflatable to form an oblong shape.
Claims18
A method of operating a balloon catheter, comprising:
- inserting a distal end of a balloon catheter through an access site into a blood vessel, the balloon catheter comprising an angled tip at the distal end, wherein the distal end of the balloon catheter comprises a balloon adjacent to the angled tip;
- inflating the balloon of the balloon catheter at the access site within the blood vessel, wherein the balloon forms an oblong shape in an inflated state, and the angled tip is positioned in an anterograde direction of the blood vessel;
- positioning a top surface of the inflated balloon adjacent the access site within the blood vessel;
- and
- rotating the inflated balloon at the access site within the blood vessel, wherein the angled tip is repositioned from the anterograde direction to a retrograde direction of the blood vessel.

A method for operating a balloon catheter, comprising:
- inserting a distal end of a balloon catheter through an access site into a blood vessel, the balloon catheter comprising a balloon comprising a top surface coupled to the distal end, a bottom surface spaced distally from the top surface, and an angled tip extending from the bottom surface along a tip axis that extends at an angle relative to a longitudinal axis of the catheter;
- inflating the balloon within the blood vessel, wherein the balloon forms an oblong shape having a length perpendicular to the longitudinal axis that is greater than its width along the longitudinal axis, and the angled tip is positioned in an anterograde direction of the blood vessel;
- positioning a top surface of the inflated balloon adjacent to the access site within the blood vessel;
- and
- rotating the inflated balloon at the access site within the blood vessel, wherein the angled tip is repositioned from the anterograde direction to a retrograde direction of the blood vessel.

A method for performing a thrombectomy, comprising:
- inserting a distal end of a balloon catheter through an access site into a body lumen of a patient, the balloon catheter comprising a balloon comprising a top surface coupled to the distal end, a bottom surface spaced distally from the top surface, and an angled tip extending from the bottom surface along a tip axis that extends at an angle relative to a longitudinal axis of the catheter;
- inflating the balloon within the blood vessel, wherein the balloon forms an oblong shape having a length perpendicular to the longitudinal axis that is greater than its width along the longitudinal axis, and the angled tip is positioned in a first direction within the body lumen;
- advancing the inflated balloon in the first direction to clear thrombus within the body lumen;
- positioning a top surface of the inflated balloon adjacent the access site within the blood vessel;
- rotating the inflated balloon within the body lumen to reposition the angled tip is repositioned in a second direction opposite to the first direction within the body lumen;
- and
- advancing the inflated balloon in the second direction to clear additional thrombus within the body lumen.
