Abstract

A catheter composed of an outer coaxial tube or relatively high flexibility and three tandemly disposed inner coaxial tube segments that vary in stiffness with the stiffest being located at the proximal end of the catheter and the least stiff ending proximal of the proximal end of the catheter. The catheter thus has four regions of different stiffness/flexibility.
