    摘要： A catheter for use in a body vessel includes a relatively stiff proximal shaft that is shaped as a tube formed with a lumen and having a proximal end and a distal end. Further, the catheter includes a relatively flexible distal tube formed with a lumen and having a proximal end and a distal end. An inflatable balloon may be attached to the outer wall of the distal tube near the distal end. The proximal end of the distal tube is attached to the distal end of the proximal shaft at a transitional joint. The transitional joint provides a gradual transition in flexibility over the length of the joint between the stiff proximal shaft and the flexible distal tube. Importantly, the transitional joint includes an extension made of a material having superelastic properties when positioned inside the body vessel. One end of the extension is attached to the distal end of the proximal shaft. The other end of the extension projects into the lumen of the distal tube. The extension may be formed as a ribbon, core wire or may constitute a tapered section of the proximal shaft.

    摘要翻译： 用于体内容器的导管包括相对刚性的近端轴，其形状为形成有内腔并具有近端和远端的管。 此外，导管包括形成有内腔并具有近端和远端的相对柔性的远端管。 可充气气囊可以在远端附近附接到远端管的外壁。 远侧管的近端在过渡关节处附接到近端轴的远端。 过渡关节在刚性近端轴和柔性远端管之间的关节的长度上提供了柔性的逐渐过渡。 重要的是，过渡关节包括当位于体内容器内时由具有超弹性的材料制成的延伸部。 延伸部的一端连接到近端轴的远端。 延伸的另一端伸入远端管的内腔。 延伸部可以形成为带状芯线，或者可以构成近端轴的锥形部分。

    摘要： Medical devices, systems, and methods for treating patients with tissue ablation include catheter systems having bi-modal steering mechanisms, which are capable of both linear and loop ablation. In other words, the catheter system may have two different steering modes: two-dimensional and three-dimensional. In the first and second steering modes, the steering actuator may cause one or more portions of the catheter shaft to bend in different planes. A steerable ablation catheter may include treatment elements such as electrodes at its distal end and along the catheter shaft, each of which may map, pace, and ablate. Optional features include a series of thermocouples for monitoring local temperatures.

    摘要： A system for treatment of a vessel lesion comprises an expandable balloon and at least one cutting string longitudinally engaged to an exterior surface of the balloon. When the balloon is in its expanded condition, a gap is formed between the at least one cutting string and the exterior surface of the balloon.

    摘要： A microsurgical balloon, with at least one incising component mounted to the surface of the balloon, includes a protective pad to prevent the outer surface of the incising component from coming into contact with and damaging the balloon surface. In particular, the protective pad is positioned on the outer surface of the balloon substantially parallel to and juxtaposed with the incising component. When the balloon is in a deflated configuration, either for insertion into the vasculature system or removal from the patient, the protective pad engages the outer surface of the incising component thereby protecting the balloon from being punctured or damaged by the incising component. The protective pad may be bonded to the outer surface of the balloon, or it may be an integral part of a homogeneous balloon structure.
