1. A system comprising:
a catheter defining a distal tip; and
a laser source;
wherein the laser source emits a fixed pulse laser beam adapted to selectively cut catheter delivered implants, including embolization coils and stents, being passed through the distal tip of the catheter;
wherein the catheter comprises:
an outer wall;
a pusher wire interior to the outer wall; and
an optical fiber embedded in the catheter,
wherein an exposed portion of the distal end of the optical fiber defines at least one of a notch or angled cut such that a fixed pulse laser beam from the laser source passed through the optical fiber is emitted inwards from the at least one of the notch or the angled cut to cut the catheter delivered implant being passed through the distal tip of the catheter, and
wherein the laser source is connected to the optical fiber embedded in the catheter.
