Patent Images
1. A method of resecting a valve, the method comprising:
- endovascularly introducing a lumen with a distal steerable tip portion to a position proximate a valve to be resected;
registering the lumen in place in the vasculature;
directing ablation energy through the lumen; and
steering the distal steerable tip portion to resect the valve.

Abstract
An endovascular tissue removal device including a lumen with a distal steerable tip portion extending from a joint portion, registration means for holding the joint portion fixed in place in the vasculature, and a source of ablation energy in communication with the lumen whereby tissue can be resected by ablation energy as the tip portion is steered within the vasculature.

3. A method of resecting a valve, the method comprising:
-
endovascularly introducing a lumen with a distal steerable tip portion to a position proximate a valve to be resected; registering the lumen in place in the vasculature; endovascularly introducing an expandable mechanism on the ventricular side of the valve and inflating the expandable mechanism to support the leaflets of the valve during resection; directing ablation energy through the lumen; and steering the distal steerable tip portion to resect the valve.
