摘要： A method and an apparatus according to an embodiment of the invention includes disposing a cover about a capillary used in a side-firing optical fiber. The cover can be used to protect the capillary when being inserted through an endoscope for medical treatment. In some embodiments, the cover can be a low-profile cover such as a coating made of a light-sensitive polymer or like material. At least a portion of the coating can be removed after insertion by exposing the light-sensitive material to laser energy transmitted from an optical-fiber-core end housed within the capillary. In other embodiments, the cover can be a slideable or moveable low-profile sleeve or metal cover. During insertion, the sleeve or metal cover is positioned over the capillary. After insertion, the sleeve or metal cover is retracted to expose the area to be treated to side-fired laser energy transmitted from the capillary.
摘要翻译： 根据本发明的实施例的方法和装置包括在侧面发光光纤中使用的毛细管周围设置盖。 当通过用于医疗的内窥镜插入时，该盖可用于保护毛细管。 在一些实施例中，盖可以是低轮廓的覆盖物，例如由光敏聚合物或类似材料制成的涂层。 通过将感光材料暴露于从容纳在毛细管内的光纤纤芯端传递的激光能量，可以在插入后至少部分涂层被去除。 在其他实施例中，盖可以是可滑动或可移动的低轮廓套筒或金属盖。 在插入期间，套筒或金属盖位于毛细管上方。 在插入之后，套筒或金属盖缩回以将待处理的区域暴露于从毛细管传递的侧火激光能量。
