    • A system and method for controllably releasing laser radiation in percutaneous laser treatment is disclosed. In a preferred embodiment, an optical fiber is inserted below the skin or into a vascular lumen to a predetermined point. The fiber is connected to a source of electromagnetic radiation such as a laser. Radiation is then delivered to the treatment site while the fiber is simultaneously drawn out to the entry point. The fiber is manually withdrawn at a predetermined rate and radiation is administered in a constant power or energy level. To maintain a constant proper energy density, the speed of withdrawal is measured and sent to a controlling mechanism. The controlling mechanism modifies the power emitted, pulse length or pulse rate to ensure that the vein or tissue receives a consistent dose of energy. In one preferred embodiment, an imaging device provides the controlling device with speed information based on fiber surface textural properties or based on a series of bar code like markings. In another embodiment, additional information is collected, such as vein diameter prior to treatment, position of the distal end of the fiber, and/or impact measurements such as vibration or temperature during treatment, and the controlling mechanism adjusts output power or pulse rate in response to measurements to maintain a desired power density.
    • 公开了一种在经皮激光治疗中可控地释放激光辐射的系统和方法。 在优选实施例中,将光纤插入皮肤下方或插入血管腔至预定点。 光纤连接到诸如激光的电磁辐射源。 然后将辐射递送到治疗部位,同时将纤维同时拉出到入口点。 以预定速率手动取出纤维,并以恒定功率或能量水平施用辐射。 为了保持恒定的适当的能量密度,测量提取速度并将其发送到控制机制。 控制机制改变发射功率,脉冲长度或脉率,以确保静脉或组织接受一致的能量。 在一个优选实施例中,成像装置为控制装置提供基于纤维表面纹理特性或基于一系列条形码标记的速度信息。 在另一个实施例中,收集附加信息,例如治疗前的静脉直径,纤维远端的位置和/或治疗期间的冲击测量例如振动或温度,并且控制机构调节输出功率或脉率 对测量的响应以保持期望的功率密度。
