Patent ID: 8448644

Claim:
A method for inducing vein spasm while performing endovascular laser ablation to treat varicose veins under visualization comprising: introducing an endoscopic catheter, cannula or other functional probe having a tip and a length into a vein, wherein the endoscopic catheter, cannula, or other functional probe comprises an optical fiber; coupling a vibration emitter to the catheter, cannula or other functional probe; using the vibration emitter to vibrate the catheter, cannula, or other functional probe such that transverse wave vibrations are generated along the catheter, cannula, or other functional probe that propagate the length of the catheter, cannula, or other functional probe at a frequency of between 10 and 3000 Hz inside the vein such that the vein spasms forcing blood out of the vein and temporarily reducing the diameter of the vein; visualizing the tip of the catheter, cannula or other functional probe; and delivering laser energy from the catheter, cannula, or other functional probe to the vein.
