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： 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 delivering laser energy via a fiber optic catheter 300. A motorized pull back device 104 may be used. The laser is preferably operated under laser energy delivery conditions that substantially prevent the formation of coagulum on the energy emitting tip of the fiber.
