Laser tissue ablation system
First Claim
1. An applicator comprising:
- a shaft with a proximal end opposite of a distal end along a longitudinal axis;
a balloon attached to the distal end of the shaft, wherein the balloon comprises a first balloon attached to the distal end of the shaft, the distal end of the shaft being within the first balloon and a second balloon within the first balloon, the second balloon being formed of a material that is less distensible than a material forming the first balloon;
a support attached to a proximal end of the shaft;
a plurality of channels extending through each of the support and the shaft in a direction parallel with the longitudinal axis; and
at least one positioning component that is mounted on the support and operable to move a fiber placed in one of the plurality of channels.

Abstract
Embodiments of the invention are directed to a laser ablation system. In one embodiment, the laser ablation system comprises a shaft, a balloon, a laser fiber and a viewing fiber. The shaft has a proximal end and a distal end. The balloon is attached to the distal end of the shaft, a portion of which is within the balloon. The laser fiber has a distal end comprising a light dispenser that is configured to deliver laser light through the balloon. The viewing fiber is configured to image an interior balloon. In accordance with another embodiment, the laser ablation system comprises a shaft, a balloon and a laser fiber. The shaft has a proximal end and a distal end. The balloon is attached to the distal end of the shaft, which is within the balloon. The balloon includes an inflated state, in which the balloon is shaped to conform to a cavity of a patient. The laser fiber has a distal end comprising light dispenser that is configured to deliver laser light through the balloon.
