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： An apparatus is disclosed for attenuating the beam of a laser. The apparatus is particularly suited for situations where a low powered aiming beam is necessary to be coaxially aligned with a full power working beam. The apparatus includes a refractive element having a pair of spaced-apart, parallel faces. A mounting arrangement is provided for selectively moving the refractive element into and out of the path of the full power laser beam. The refractive element is mounted such that when it is moved into the path of the laser beam, the beam will be split into primary and secondary beams. The primary beam will exit the refractive element along a path displaced from the incoming beam. The power of this exiting primary beam can be captured through a beam dump. The secondary beam is a product of at least two internal reflections within the refractive element. The secondary beam is highly attenuated and travels along the same path as the incoming beam. The secondary beam may be used for aiming since the full power beam will travel along the same path as the attenuated beam after the refractive element is moved out of its path.
摘要翻译：公开了用于衰减激光束的装置。该装置特别适用于低功率瞄准光束与全功率工作光束同轴对准的情况。该装置包括具有一对间隔开的平行面的折射元件。提供了用于选择性地将折射元件移入和移出全功率激光束的路径的安装布置。折射元件被安装成使得当其移动到激光束的路径中时，光束将被分裂成主光束和次光束。主光束将沿着从入射光束移位的路径离开折射元件。这个退出的主光束的能量可以通过光束转储来捕获。次级光束是折射元件内的至少两个内部反射的乘积。次级光束被高度衰减并沿与入射光束相同的路径传播。次光束可以用于瞄准，因为在折射元件移出其路径之后，全功率光束将沿着与衰减光束相同的路径行进。
