    摘要： Inducing thrombolysis of thermally induced thrombus occurring during endovenous ablation of varicose veins by introducing an optical fiber laser deliver device with optical fiber portion and with an energy emitting tip at its distal end into the varicosed vein to be treated, emitting pulsed, laser energy with sufficient energy to close and destroy varicose veins to the emitting tip of the optical fiber laser delivery device, thereby inducing laser thrombolysis of coagulated blood which accumulates at the energy emitting tip of the fiber when the fiber is caused to emit energy in the presence of uncoagulated blood and minimizing adverse effects associated with thermally induced thrombus within a varicose vein.

    摘要： This invention is an improved method and device for treating varicose veins 200 or the greater saphenous vein 202. The method comprises the use of infrared laser radiation in the region of 1.2 to 2.2 um in a manner from inside the vessel 200 or 202 such that the endothelial cells of the vessel wall 704 are damaged and collagen fibers in the vessel wall 704 are heated to the point where they permanently contract, the vessel 200 or 202 is occluded and ultimately resorbed. The device includes a laser 102 delivered via a fiber optic catheter 300 that may have frosted or diffusing fiber tips 308, or that may be provided with a protective spacer. A motorized pull back device 104 may be used, and a thermal sensor 600 may be used to help control the power required to maintain the proper treatment temperature.

The method comprises the use of infrared laser radiation in the region of 1.2 to 1.8 um in a manner from inside the vessel 200 or 202 such that the endothelial cells of the vessel wall 704 are damaged and collagen fibers in the vessel wall 704 are heated to the point where they permanently contract, the vessel 200 or 202 is occluded and ultimately resorbed.

A motorized pull-back device 104 is used, and a thermal sensor 600 may be used to help control the power required to maintain the proper treatment temperature.
