摘要： 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.

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 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. The device includes a laser 102 delivered via a fiber optic catheter 300 that may have frosted or diffusing fiber tips 308. 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.

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.

摘要： 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.

摘要： A handpiece and method of use for laser-assisted liposuction for melting, disrupting, and removing cellulite and adipose tissue. Electromagnetic energy is used to selectively melt or disrupt cellulite and adipose tissue and ablate the collagen in the constricting bands of connective tissue that causes the dimpled appearance of cellulite and adipose tissue, while avoiding damage to the surrounding fatty cells.

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.
