Abstract
A transluminal balloon laser catheter has an inflatable distal tip formed by an elongated balloon sealed at the distal end of a length of catheter tubing, and inflatable to an operating configuration in which the balloon effectively extends the distal end of an optical fiber lumen through the catheter tubing. One embodiment of the balloon is formed with a substantially planar distal face, transverse with respect to the extension of the balloon. In an alternative embodiment, the distal face of the balloon is formed as a truncated cone, converging proximally from a radially outward longitudinal balloon section to a radially inward longitudinal balloon section whereby the distal tip of an optical fiber, even when advanced distally of the optical fiber lumen, is proximal with respect to the most distal portion of the balloon.
