1. A system comprising:
a sheath having a proximal end and a distal end and a lumen therein, the lumen being configured to translatably receive a laser catheter having a distal end;
a handle coupled to the sheath; and
a laser treatment mode selection system coupled to the handle, the laser treatment mode selection system comprising a user input being actuatable to configure the laser catheter from a first laser treatment configuration to a second laser treatment configuration and vice versa, in the first laser treatment configuration the distal end of the laser catheter being disposed distally from the distal end of the sheath, and in the second laser treatment configuration the distal end of the laser catheter being disposed proximally from the distal end of the sheath and within the lumen, thereby creating a cavity between the distal end of the laser catheter and the distal end of the sheath,
wherein the first laser treatment comprises laser ablation and the second laser treatment comprises laser induced pressure wave emission.
