Patent abstract
A catheter has excellent torque transmissivity and excellent flexibility, thus enabling easy insertion of the catheter into a blocked portion of a blood vessel. Additionally, the catheter easily restores to its original form even when the catheter is curved and deformed a large amount. Thus, a break at a border area between a catheter main body part and a distal end tip is prevented when the catheter is bent and deformed. This improves the operability of the catheter with a combination device such as a guide wire. The catheter includes a hollow coil body formed of at least one helically wound stranded wire. The at least stranded wire includes a plurality of wires wound into a helical structure.
