摘要：
Embodiments include a catheter system comprising an elongated housing having a housing channel disposed between a first proximal end and a first distal end. The first distal end includes a ramp, having an inclining proximal section and an apex section, and a nose section. The catheter system further includes a rail wire channel in communication with the ramp but not the nose section and a laser delivery member being at least partially disposed within the housing channel and movable therein. In some embodiments, the catheter system includes a rail wire fixedly attached to and terminating at the first distal end of the elongated housing, wherein the rail wire extends through the rail wire channel, and wherein the laser delivery member is slidably coupled to the rail wire.
