ABSTRACT:
A catheter and its method of use provide flexibility attributes while exhibiting torsional rigidity properties which are advantageous for transluminal treatments and analyses. The catheter includes a shaft component having a generally helically wound coil with a skin or webbing supported by the coil. The skin or webbing generally follows movement of the coil, including movement of adjacent coil windings toward and, in some instances, away from each other. The skin or webbing contributes negligibly to the resistance of the catheter to axially directed compressive forces, especially during implantation or insertion, and the catheter exhibits exceptional kink resistance through very tortuous vessels of the body.
