摘要： A method and apparatus for coupling laser energy into an optical fiber employs a laser (12) with a concave reflector (16) and a planar reflector (18), a plano-convex focusing lens (22) and an optical fiber array (28). A divergent laser beam (20) is emitted from the laser and is focused to a beam waist (24) by the plano-convex lens (22). Within the beam waist (24) exists a soft focal plane (26) wherein the laser energy is relatively homogeneous across the beam's cross section. An optical fiber array (28) is placed within the beam waist (24) such that the soft focal plane substantially matches the size and shape of the proximal end of the optical fiber array (28). Thus, laser energy is coupled to the optical fiber array (28) at the soft focal plane (26) within the beam waist (24) at a fluence level below the fluence damage threshold of the optical fiber array (28) and in a relatively homogeneous fashion across the cross section of the optical fiber array (28).
摘要翻译：用于将激光能量耦合到光纤中的方法和装置采用具有凹面反射器（16）和平面反射器（18），平凸聚焦透镜（22）和光纤阵列（28）的激光器（12）。发射激光束（20）从激光器发射并通过平凸透镜（22）聚焦到光束腰部（24）。在光束腰部（24）内存在柔性焦平面（26），其中激光能量在横梁的横截面上相对均匀。光纤阵列（28）被放置在光束腰部（24）内，使得软焦平面基本上与光纤阵列（28）的近端的尺寸和形状相匹配。因此，激光能量以低于光纤阵列（28）的注量损伤阈值的注量水平处在光束腰部（24）内的软焦平面（26）处耦合到光纤阵列（28），并且在相对跨越光纤阵列（28）的横截面的均匀方式。

摘要： The present invention is a turn limiter for a catheter with a twistable tip. The catheter having a flexible wall for use in complex twisting anatomy contains a torque wire (15, 25, 35) or a torquable guide wire lumen. The proximal end of the torque wire protrudes from the proximal end of the catheter and is attached to a turn limiter (10). Rotation of the turn limiter imparts a torque to the torque wire or torquable guide wire lumen. The turn limiter allows limited rotation of the proximal end of the torque wire or torquable guide wire lumen without axial dislocation; may indicate the amount of torque applied to the torque element; and may also have a friction means for preventing back rotation.

摘要： The present invention is a catheter (10) with a twistable tip. The catheter having a flexible wall for use in complex twisting anatomy contains a torque wire (50) or a torquable guide wire lumen (20). The torque wire or torquable guide wire lumen extends through the length of the catheter and is attached to the catheter at or near the distal end thereof. The distal face of the catheter is angled to self align the catheter with an obstruction upon insertion. The proximal end of the torque wire protrudes from the proximal end of the catheter and is attached to a turn limiter (130). Rotation of the turn limiter imparts a torque to the torque wire or torquable guide wire lumen which is transmitted through the catheter to the distal end of the catheter where the applied torque twists the distal tip to manually align the tip with an obstruction.
