Abstract:
1. A catheter comprising: an elongated housing having a central axis between a proximal end and a distal end, said housing having a channel extending from the proximal end to a cavity formed in the housing near said distal end, the elongated housing further, including a tip at the distal end, the tip having a guidewire lumen extending therethrough and being in communication with the cavity, wherein the housing further includes an inflatable member located in the vicinity of the cavity and proximal to the tip; a laser delivery member having a proximal end and a distal end and comprising at least one optical fiber, said laser delivery member being at least partially disposed within said channel, wherein the laser delivery member further includes a guidewire lumen; wherein the inflatable member is adapted to move said distal end of said laser delivery member laterally away from said central axis of said elongated housing when the inflatable member is inflated; and a guidewire extending through the guidewire lumen of the laser deliver catheter, over the inflatable member and through the guidewire lumen at the tip of the, housing, said guidewire being adapted to position the distal end of said laser delivery member laterally away from and generally parallel to said central axis when the distal end of the laser delivery member is at or beyond the inflatable member and the inflatable member is inflated.
