    Abstract: Embodiments of a balloon biasing laser catheter are provided. In some embodiments, the laser catheter may include a distal tip that extends from the distal end of the catheter from a point near the light guide aperture. The distal tip may be disposed at the periphery of the catheter. In some embodiments, a balloon may be disposed between the light guide aperture and the distal tip, such that the a light guide extending from the aperture may be disposed proximate with the distal tip having the balloon in between. A retaining wire may be coupled with the distal tip and slidably coupled with the light guide. The retaining wire may keep the light guide biased relatively parallel with the distal tip and/or the catheter body when the balloon is inflated. The light guide may include a guidewire lumen the extends to the distal end of the distal tip.

    Abstract: Embodiments of the invention are directed towards a rapid exchange catheter configured for insertion into a subintimal space and crossing an occlusion in a subintimal space. The catheter includes a proximal end, a distal end, a first lumen configured to receive a first wire, the first lumen extending longitudinally through a least a lateral port of the catheter, and a second lumen having at least a portion distal of the lateral port and extending through at least the distal end of the catheter. The catheter also includes an exchange port, arranged on an exterior portion of the catheter configured to receive a second wire and second rapid exchange port in communication with the second lumen. Moreover, other embodiments of the invention are directed towards methods for using the rapid exchange catheter to cross an obstruction in a vessel, e.g., a total or partial occlusion, in a subintimal space.
