Abstract
This catheter is suitable for treating a tissue target within the body, which target is accessible through the vascular system. Central to the catheter is the use of a multi-component section having an interior stiffener comprising a spirally cut tubing member and an exterior tubing member. Depending upon the choice of materials of construction for the interior and exterior layers (and their respective thicknesses), the section may be placed at any place within the length of the catheter. The multi-component section is kink-resistant, has good pushability and flexibility, and (in some variations) has variable flexibility along the axis of the spirally cut section.
