    • PROBLEM TO BE SOLVED: To provide a medical optical fiber, an optical fiber device and a bundle fiber to be applied to a tubular tissue of a living body for removing a blood clot deposited on the inner wall of the tubular tissue. SOLUTION: The optical fiber 20 which can be inserted into the tubular tissue 15 inside the living body comprises a glass core layer 11, a coating core layer 12 which coats the glass core layer 11, and a cladding layer 13 which coats the coating core layer 12 and which has a plurality of openings 23 in the longitudinal direction of the optical fiber 20. The width of the opening 23 in the longitudinal direction of the optical fiber 20 is narrow in the entrance area of the optical fiber 20, and gradually becomes wider as separated from the entrance area in the longitudinal direction of the optical fiber 20. The optical fiber is applied to the optical fiber device, and a plurality of the optical fibers are bundled to make the bundle fiber. COPYRIGHT: (C)2008,JPO&INPIT
    • 要解决的问题:提供一种应用于生物体的管状组织的医用光纤,光纤装置和束纤维,用于去除沉积在管状组织的内壁上的血块。 解决方案:可插入生物体内的管状组织15中的光纤20包括玻璃芯层11,涂覆玻璃芯层11的涂层芯层12和涂覆玻璃芯层11的包覆层13 涂布芯层12,并且在光纤20的长度方向上具有多个开口23.光纤20的长度方向的开口23的宽度在光纤20的入射面积窄, 在与光纤20的长度方向的入射区域分离的状态下逐渐变宽。将光纤施加到光纤装置,并且将多根光纤捆扎以制造束纤维。 版权所有(C)2008,JPO&INPIT
