A catheter device (K, K, Kand K) has a flexible hollow tube body () formed by a plurality of austenitic stainless steel wires () cylindrically stranded to provide a hollow structure. An inner surface of the flexible hollow tube body () has a convex-concave structure represented by the stainless steel wires () to provide helical grooves (). A leading distal end of the flexible hollow tube body () is formed into a knife-edge circle configuration to provide a knife-edge circle front (), thus imparting a perforative capability to improve its quality and performance.
