Abstract
A novel proximal shaft design used for the manufacture of a catheter. In particular, the proximal shaft design provides excellent stiffness and kink resistance with a reduced outer catheter shaft diameter for improved catheter performance. The proximal shaft design incorporates a shaft with radially extending ridges that have inset regions positioned between adjacent ridges. The catheter may be used in delivering and maintaining a radiation source in a patient's body lumen, such as a coronary artery, for a specified period of time. The proximal shaft design can be applied to other treatments and treatment sources, as well as, other catheter designs.
