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.

Laser tissue ablation system

Embodiments of a laser ablation system include 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, a portion of which is disposed within the balloon. A light dispenser at a distal end of the laser fiber is configured to deliver laser light through the balloon. A central axis of the balloon is aligned with a longitudinal axis of the shaft. The balloon has a variable transparency such that the transmission of laser light through the balloon is non-uniform along the central axis. Accordingly, an energy of laser light transmitted from the light dispenser through the balloon to the targeted tissue varies due to the variable transparency of the balloon.

An ablation device comprises a balloon having an open proximal end and a closed distal end. A cylindrical tube extends into the balloon through the proximal end. An end support member is positioned at the distal end of the balloon. The end support member comprises a cylindrical portion facing the proximal end of the balloon. The cylindrical portion is received within a bore at the distal end of the tube. A seal is formed between the proximal end of the balloon and the cylindrical tube.
