    Abstract: A medical guide wire (1) is made in which at least a fluororesin coating layer (13) is formed on the surface of a metal wire (11), wherein particulate matter is present in the fluororesin coating layer (13), and the fluororesin coating layer covers the particulate matter and at least some of the particulate matter is formed in surface protrusion-shaped projections (14). It is thus possible to provide a medical guide wire that is inexpensive to manufacture and whose strength is unaffected and frictional resistance is low, and manufacturing method for the same.

    Abstract: A tubular article (31) is provided by molding and thermosetting a mixture including polyimide and fluororesin particles. At least a part of the fluororesin particles present in the vicinity of a surface layer of the tubular article (31) is melt-flowed into the outer face or both faces of the tubular article and oozes out so as to form a fluororesin coating partially or entirely. The tubular article (31) can be manufactured by applying on the outer face of a mold a dispersion prepared by adding fluororesin particles to a polyimide precursor solution and casting to have a predetermined thickness, heating for imidization so that the maximum temperature for the imidization is set higher than the melting point of the fluororesin, cooling and subsequently separating the tubular article from the mold. The present invention provides a tubular article with low dynamic friction coefficient particularly for the outer face, with high durability and that can be manufactured at low cost, and a method of manufacturing the tubular article.

    Abstract: A medical tube includes a mixture component including a polyimide resin and a fluorine resin, the mixture component being heated and cured. The fluorine resin melts and is precipitated on at least an inner face of the tube, and the inner face or the inner and outer faces of the tube is a low friction resistance face. This tube is obtained by polymerizing aromatic tetracarboxylic acid dehydrate and aromatic diamine in a polar solvent to be a polyimide precursor solution; adding a fluorine resin in the polyimide precursor solution or during the polymerizing step to prepare a mixed solution of the polyimide precursor and the fluorine resin; applying the mixed solution to an outer face of a core wire so as to have a predetermined thickness; applying heat so as to allow conversion to an imide, where a highest temperature for the conversion to an imide is a temperature exceeding a melting point of the fluorine resin; and cooling it and separating the core wire and the medical tube. Thereby, a medical tube can be provided with a small outer diameter and a small wall thickness and have excellent mechanical characteristics. The inner or the inner and the outer faces of the tube have a low friction resistance. A method for manufacturing the same also can be provided.
