Laser catheter with moveable integral fixation wires

摘要

A laser catheter for irradiation of human myocardial tissue containing a movable feedback mechanism for monitoring the damage created by laser irradiation, and which is usable with standard catheters designed for angiography and angioplasty. Means for sensing distal temperature are provided in the form of a plurality of movable thermocouples, along with the ability to cool the fiber optic and distal tip with a flushing solution. Flushing of the area adjacent to the tip is provided for by a fluid which travels the length of the laser catheter.
