Abstract
A catheter comprises a flexible tubular member having a drive cable disposed in a lumen thereof. A work element is secured to a distal end of the lumen while a coupling member for rotating the cable secured to the proximal end thereof. The cable includes a more flexible end located within the distal region of the catheter and a less flexible section located within the proximal region of the catheter. In this way, the drive cable is able to transmit torque sufficiently from the proximal end to the distal end even when the catheter is subject to tortuous twisting and bending as a result of positioning within confined regions of the body, such as the vascular system.
