This invention is an improved method and device for treating varicose veinsor the greater saphenous vein. 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 vesselorsuch that the endothelial cells of the vessel wallare damaged and collagen fibers in the vessel wallare heated to the point where they permanently contract, the vesseloris occluded and ultimately resorbed. The device includes a laserdelivered via a fiber optic catheterthat may have frosted or diffusing fiber tips. A motorized pull-back deviceis used, and a thermal sensormay be used to help control the power required to maintain the proper treatment temperature.

System and method for endovenous treatment of varicose veins with mid infrared laser

The present invention describes a method of treating restless leg syndrome by eliminating venous reflux in an underlying vein. The malfunctioning vein can be removed or ablated by inserting a catheter into the vein that transmits sufficient energy to coagulate or ablate the lining of the vein causing it to permanently close, eliminating the source of venous reflux and the symptom of restless leg syndrome.

Restless leg syndrome treatment

Improved devices and methods for removing blood from a blood vessel in preparation for endovenous laser ablation are described. The improved methods include one or more of: placing the patient in the Trendelenburg position, applying external compression around the vein, massaging the vein, cooling the vein externally, encouraging spasming of the vein, and removing blood with a suction device.

Endovenous laser treatment for varicose veins

This invention is an improved method and device for treating varicose veinsor the greater saphenous vein. 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 vesselorsuch that the endothelial cells of the vessel wallare damaged and collagen fibers in the vessel wallare heated to the point where they permanently contract, the vesseloris occluded and ultimately resorbed. The device includes a laserdelivered via a fiber optic catheterthat may have frosted or diffusing fiber tips, or that may be provided with a protective spacer. A motorized pull back devicemay be used, and a thermal sensormay be used to help control the power required to maintain the proper treatment temperature.
