Abstract: A fixture is provided for attachment to a device to be inserted into a nasal cavity. Further, the fixture is a nasal cavity insertion device fixture formed of a wire rod. The fixture includes a first wire rod part, a second wire rod part, and a third wire rod part. The second wire rod part is connected to the first wire rod part and formed by folding back the wire rod so as to be opposed to the first wire rod part. The third wire rod part is connected to the second wire rod part and formed by bending the wire rod so as to be disposed oppositely to a side of the second wire rod part facing the first wire rod part.

Abstract: A nasal cavity insertion device is provided that includes a tubular main body part, at least one elastically deforming part disposed on the outer peripheral surface of the tubular main body part, and a water soluble holding part. The water soluble holding part holds the elastically deforming part in a diameter-reduced state.

Abstract: A nasal cavity insertion device fixture, whereby the displacement or detachment of a nasal cavity insertion tube is prevented during the sleep of a patient of sleep disorder. A nasal cavity insertion device fixture makes contact with the inner surface of a nasal passage in order to fix an insertion device inserted into the nasal cavity. The nasal cavity insertion device fixture preferably includes a tubular contact portion with an outer peripheral surface thereof which makes contact with the inner surface of the nasal passage.

Abstract: A method for the manufacture of a medical wire includes manufacturing a fluororesin-coated wire and irradiating with infrared radiation. The fluororesin-coated wire is manufactured with a fluororesin-containing liquid, or fluororesin powder body being applied to the outer circumference of a superelastic alloy wire or of a resin-coated superelastic alloy wire. The fluororesin-coated wire is irradiated with a defined wavelength of infrared radiation for a defined period of time.

Abstract: A medical device for insertion into the human body has improved sliding characteristics. The medical device for insertion into the human body includes a substrate having given shape, and an agent for improving the sliding characteristics having a hydrophilic block and a hydrophobic block, and coating the hydrophobic surface.

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.

Abstract: The subject of the present invention is to offer a method for the manufacture of a medical wire that can elicit the superior qualities of a fluororesin while maintaining the elastic modulus of a superelastic alloy wire. The method for manufacturing a medical wire that relates to the present invention is provided with a process for manufacturing a fluororesin-coated wire and a process for irradiating with infrared radiation. In the process for manufacturing the fluororesin-coated wire, the fluororesin-coated wire is manufactured by a fluororesin-containing liquid, or fluororesin powder body being applied to the outer circumference of a superelastic alloy wire or of a resin-coated superelastic alloy wire. In the infrared irradiation process, the fluororesin-coated wire is irradiated with a defined wavelength of infrared radiation for a defined period of time.

Abstract: A medical device for insertion into the human body has improved sliding characteristics compared to similar devices with fluororesin surfaces. The medical device for insertion into the human body includes a substrate having given shape, and an agent for improving the sliding characteristics having a hydrophilic block and a hydrophobic block, and coating the hydrophobic surface.
