摘要： A telescoping catheter is adapted to provide improved support and protection for a drive cable by providing, in addition to an outer sheath and a telescoping sheath, an inner sheath surrounding the drive cable. The outer sheath has a relatively larger diameter, to allow for a flared end of the telescoping sheath to pass freely within the outer sheath. The inner sheath protects and supports the drive cable when the telescoping catheter is extended and the drive cable would otherwise only be protected and supported by the outer sheath having a diameter too large to provide the desired amount of support and protection for the drive cable.

摘要翻译： 伸缩导管适于通过提供围绕驱动电缆的内护套，除了外护套和伸缩护套外，还提供用于驱动电缆的改进的支撑和保护。 外护套具有相对较大的直径，以允许伸缩护套的扩口端在外护套内自由通过。 当伸缩导管伸展时，内护套保护和支撑驱动电缆，而驱动电缆将仅由外护套保护和支撑，外护套的直径太大，无法为驱动电缆提供所需数量的支撑和保护。
