Abstract
Devices and methods are discussed directed to the use of a low profile laser ablation catheter for use in laser ablation removal of arterial plaque blockages to restore blood flow in the treatment of arteriovenous fistulas. Also discussed are devices and methods directed to packaging, long term storage and sterilization of liquid core ablation catheters.
Claims8
A method of treating an arteriovenous fistula of a patient, comprising:
- axially advancing a liquid core ablation catheter through a blockage that is disposed within or adjacent the arteriovenous fistula while emitting pulsed ultraviolet laser ablation energy from an active emitting surface of a distal end of the liquid core ablation catheter which comprises at least about 50 percent of an area of the distal end of the liquid core ablation catheter, and ablating the blockage and debulking the blockage.
