Patent ID: 8702773

Claim:
A laser catheter comprising: a catheter body including a central axis, a distal end, a proximal end, and a cavity disposed within a periphery of the catheter body proximal to the distal end, wherein the cavity is cut through a portion of the periphery of the catheter body; an inner tube including a port at the distal end of the catheter body, the inner tube positioned eccentric relative to the central axis of the catheter body; a light guide disposed within the catheter body and extending from the proximal end to the distal end; and a balloon disposed within the cavity, wherein the balloon is configured to inflate inside the cavity, wherein a portion of the inflated balloon extends outside of the cavity proximal to the distal end of the catheter body, and wherein the inflated balloon is slidably coupled with the catheter body allowing the catheter body to move relative to the inflated balloon and allowing the inflated balloon to move relative to the catheter body in a longitudinal direction of the central axis, the inflated balloon remaining proximal to the distal end of the catheter body.
