Abstract
A catheter is disclosed which includes an over-the-wire type balloon catheter with a guide wire wherein the catheter includes a polyethylene inner tube and an outer tube having a relatively stiff proximal outer section, a midshaft section of lesser stiffness, and a tapering distal outer section of the least stiffness. An inflatable balloon is connected to the distal ends of the inner tube and the outer tube. The guide wire may be removed from and inserted into the guide wire lumen at either end of the catheter.
