Lasers, Excimer, Angioplasty

Definition : Excimer lasers designed to deliver their energy into the vessels to eliminate areas of narrowing (i.e., angioplasty). These lasers consist of a pulsed excimer laser generator and a delivery system including optical fibers and a catheter. Some coronary devices include a steerable guide wire with an array of optical fibers; they combine the mechanical properties of the guide wire with the laser energy to facilitate the ablation of areas of total occlusion. Angioplasty excimer lasers are mostly used in laser-assisted angioplasty of totally occluded coronary arteries; some are also used in the treatment of total occlusions in the peripheral vessels.
