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

A device and method to improve the ultrasound visibility of a catheter placed inside the body is described. The catheter is sonically vibrated by an external driver device that transmits the acoustic vibration down the catheter and inside the body. An ultrasound transducer is used to pick up the ultrasound vibrations directly or detects the sonic vibrations using a Doppler mode ultrasound machine.

Sonic endovenous catheter

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.
