Abstract: A valve body, e.g. a valve body adapted to be disposed in a connector to be connected to a catheter, has an opening/closing part which opens upon inserting a member into the opening/closing part and which closes upon withdrawing the member from the opening/closing part. The valve body includes a main body part made of a silicone rubber and a surface layer disposed on a surface of the main body part. This surface layer serves as a sliding surface which, when a guide wire has been inserted into the opening/closing part, slides on the guide wire. The surface layer is constituted mainly of silicon oxide and hence improves the sliding properties of the guide wire. Thus, the valve body is reduced in the resistance of sliding on the guide wire.

Abstract: A method of manufacturing an elongated medical body coated with a fluororesin involves applying the fluororesin to the outer surface of an elongated body having a metallic substrate, and heating the elongated body with the fluororesin applied through operation of a heat source, while cutting off direct radiation of infrared rays generated from the heat source.

Abstract: Disclosed herein is a medical elongate member including a elongate base material, a resin layer formed to coat or to be integral with the surface of at least a part of the base material, and a plurality of projections dispersed uniformly in a surface of the resin layer.

Abstract: A guide wire includes a wire body, a wire distal end section at the distal side of the wire body and integrally formed in one piece with the wire body, a flat plate-shaped section provided at a distal end section of the guide wire and at the wire distal end section, a coating layer formed on a surface of the wire body, and a coil mounted at the wire distal end section. A surface part of the flat plate-shaped section preferably has a residual stress higher than that an internal part of the flat plate-shaped section.
