具有改善的柔性的导管
摘要：
一种神经调节导管包括细长轴和神经调节元件。该轴包括同心设置于外壁中的海波管，并具有用以增加导管柔性的切口(122)。该轴包括沿着绕该轴的纵向轴线延伸的螺旋路径(126)的两个或多个第一切割形状(128)和两个或多个第二切割形状(130)。第一切割形状构造成至少部分地抵抗响应于该轴上的纵向压缩和张紧以及沿第一周向的轴上扭曲所引起的变形。第二切割形状构造成至少部分地抵抗响应于该轴上的纵向压缩和沿第一周向与第二相反周向的轴上的扭曲所引起的变形。
摘要（英）：

A neuromodulation catheter includes an elongate shaft and a neuromodulation element. The shaft includes a hypotube concentrically disposed within an outside wall and includes a cut (122) to increase the flexibility of the catheter. The shaft includes two or more first cut shapes (128) and two or more second cut shapes (130) along a helical path (126) extending around a longitudinal axis of the shaft. The first cut shapes are configured to at least partially resist deformation in response to longitudinal compression and tension on the shaft and torsion on the shaft in a first circumferential direction. The second cut shapes are configured to at least partially resist deformation in response to longitudinal compression on the shaft and torsion on the shaft in both first and second opposite circumferential directions.
