    • A curved catheter comprising a solid-walled metal tube with varying stiffness along it length. The catheter includes a tube comprising material capable of being variably heat-treated to set different physical properties along the length of the tube. The tube has a distal region with a pre-curved shape, a proximal region, distal and proximate ends, and a lumen there through. The proximal region is configured to be flexible at a first temperature and to become stiffer at a second temperature, the second temperature being higher than the first temperature. The material for the tube may be a superelastic material, such as nitinol. The superelastic material may also be capable of deformation of the pre-curved shape at the first temperature and recovery of the pre-curved shape at the second temperature. Methods of making the catheter are also disclosed.
    • 一种弯曲导管,包括沿其长度具有不同刚度的固体金属管。 导管包括管,其包括能够被可变地热处理以沿管的长度设定不同物理性质的材料。 管具有具有预弯曲形状的远端区域,近端区域,远端和近端部以及通过其的内腔。 近端区域被配置为在第一温度下是柔性的并且在第二温度下变硬,第二温度高于第一温度。 管的材料可以是超弹性材料,例如镍钛诺。 超弹性材料还可能能够在第一温度下变形预弯曲形状并在第二温度恢复预弯曲形状。 还公开了制造导管的方法。
