Abstract: The intravascular catheter has a polymeric inner tube, a reinforcing inner jacket which is spirally wound over the inner tube and which becomes progressively softer from a proximal end to a distal end, and a polymeric outer sheath extruded over the inner jacket. The reinforcing jacket includes helical coiled wires wound over the inner tube in order to provide improved multi-axial mechanical properties.

Abstract: The intravascular catheter has two segments; a proximal segment with high stiffness and a distal segment with lower stiffness. The catheter can also have an intermediate segment of lower stiffness than the proximal segment and higher stiffness than the distal segment. The catheter comprises a polymeric inner tube, a reinforcing inner jacket which is spirally wound over the inner tube and which becomes progressively softer from a proximal end to a distal end, and a polymeric outer sheath extruded over the inner jacket according to the teachings of U.S. Pat. No. 5,445,624. The reinforcing jacket comprises helical coiled wires or fibers of various materials and layers wound over the inner tube in order to provide improved multi-axial mechanical properties, such as torque, compression, tension and anti-kinking characteristics.
