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： 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 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.
摘要翻译：具有安装到气囊表面的至少一个切割部件的显微外科气囊包括防止切割部件的外表面与球囊表面接触并损坏气囊表面的保护垫。特别地，保护垫位于气囊的外表面上，基本上与切割部件平行且并置。当气囊处于放气构型时，为了插入脉管系统或从患者移除，保护垫接合切割部件的外表面，从而保护气球不被切割部件刺穿或损坏。保护垫可以结合到球囊的外表面，或者它可以是均质球囊结构的整体部分。
