Abstract
A catheter device (K, K1, K2 and K3) has a flexible hollow tube body (1) formed by a plurality of austenitic stainless steel wires (2) cylindrically stranded to provide a hollow structure. An inner surface of the flexible hollow tube body (1) has a convex-concave structure represented by the stainless steel wires (2) to provide helical grooves (30). A leading distal end of the flexible hollow tube body (1) is formed into a knife-edge circle configuration to provide a knife-edge circle front (3), thus imparting a perforative capability to improve its quality and performance.
