摘要： A bidirectional steering catheter comprising a distal electrode assembly, a flexible tip assembly, an elongated shaft having a central lumen running the length of the shaft, and a handle/actuator. A plurality of ring electrodes are attached to the surface of the flexible tip assembly. Signal wires running the length of the catheter are electrically connected to each ring electrode. At least two pull cables having first and second ends extend distally through the central lumen. The first end of each pull cable is attached to the handle/actuator. The second end of each pull cable is attached to the distal electrode assembly, such that the distal electrode assembly may be moved between a first and a second position within a single plane by manipulating the handle/actuator. At least two reinforcement members are located inside the flexible tip assembly. Each reinforcement member has a proximal section, a middle section and a distal section. Each proximal section has a larger diameter than each middle section, thus being stiffer than the middle section. This variable stiffness along the length of the each reinforcement member distributes stresses evenly along the length of the tip assembly.
摘要翻译：一种双向转向导管，包括远端电极组件，柔性尖端组件，具有延伸轴的长度的中心腔的细长轴和手柄/致动器。多个环形电极附接到柔性末端组件的表面。运行导管长度的信号线与每个环形电极电连接。至少两个具有第一和第二端的牵拉电缆向远侧延伸穿过中心腔。每个拉线的第一端连接到手柄/执行器。每个拉电缆的第二端连接到远端电极组件，使得远端电极组件可以通过操纵手柄/致动器在单个平面内在第一和第二位置之间移动。至少两个加强构件位于柔性末端组件的内部。每个加强构件具有近端部分，中部部分和远侧部分。每个近端部分具有比每个中间部分更大的直径，因此比中间部分更硬。沿着每个加强构件的长度的这种可变刚度沿尖端组件的长度均匀地分布应力。

摘要： An ablation catheter comprising, in an exemplary embodiment, a probe having a proximal end and a distal end and an electrode which is axially displaceable along the probe. A first pull cable is attached to the electrode, extends from the electrode towards the distal end of the probe, and doubles back through the catheter for pulling the electrode toward the distal end of the probe. The first pull cable is disposed within a lumen formed in the catheter that extends substantially from the distal end to the proximal end. A second pull cable is attached to the opposite end of the electrode and extends from the electrode toward the proximal end of the catheter for pulling the electrode away from the distal end. The second pull cable is disposed within a lumen formed in the catheter. Both pull cables are coupled to an actuator mechanism at the proximal end of the catheter for effecting axial movement of the electrode relative to the distal tip of the probe by selectively tensioning the respective pull cables.
摘要翻译：在示例性实施例中，消融导管包括具有近端和远端的探针以及沿着探针轴向移动的电极。第一拉电缆连接到电极，从电极延伸到探针的远端，并通过导管翻倍，以将电极拉向探针的远端。第一拉电缆设置在形成在导管中的内腔中，其基本上从远端延伸到近端。第二拉电缆连接到电极的相对端并从电极延伸到导管的近端，用于将电极从远端拉出。第二拉索设置在形成在导管内的内腔中。两个拉电缆在导管的近端处联接到致动器机构，以通过选择性地拉紧相应的拉电缆来实现电极相对于探头的远端的轴向运动。
