1. An endovascular tissue removal device comprising:
- a lumen including 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.

13. An endovascular heart removal device comprising:
-
a catheter including a deflectable tip;
a laser source;
an optical fiber within the catheter connected to the laser source; and
an inflatable balloon for registering the deflectable tip in vasculature to resect a heart valve with laser energy as the deflectable tip portion is used to steer the distal end of the optical fiber within vasculature. - View Dependent Claims (14)
