Examples include those made of polyvinyl chloride, polyimide and mixtures thereof. A coil 11 is wound around the outer circumference of the tube body 10. The coil 11 is preferably composed of a rectangular wire. As the flat wire, stainless wire, piano wire, tungsten wire, nickel-titanium alloy wire, etc. are made into a flat shape by rolling, and the flat metal wire of the above metal wire is further formed into a small cross-sectional shape by rolling. And the like. The coil 11 is wound around the tube body 10 in either a right-handed or left-handed single-layer winding or a left (right) winding and at least a right (left) winding. The drawing shows a left and right two-layer winding state, which is a particularly preferable embodiment. The coil may be a round wire.

て凹凸を形成して密着度の向上を図ることが好ましい。Reference numeral 12 is a braided body wound around the outer surface of the coil 11, and a braided body is particularly preferable. As the constituent material of the braided body 12, for example, the same constituent material as the constituent material of the coil 11 is illustrated, and the constituent material of the coil 11 may be the same material or different materials. Further, by making the coil and / or the braided body metallic, the X-ray contrast property can be enhanced. Reference numeral 13 is a heat-shrinkable coating layer that covers the outer surface of the braided body 12. The heat-shrinkable coating layer 13 is, for example, PTF.
It is composed of E (polytetrafluoroethylene), PE (polyethylene), PVA (polyvinyl chloride), a resin containing fluorine (polytetrafluoroethylene, etc.) and the like. In particular, if the tube is made of a resin containing fluorine, when the tube is inserted into the body, a thrombus is less likely to be generated, compatibility with a living body is improved, and friction with a living tissue is reduced, resulting in excellent operability. . In addition, it is preferable that unevenness is formed on the inner surface of the heat-shrinkable coating layer 13 in order to increase the adhesion to the braid. The unevenness is formed by, for example, an etching process or the like. For example, in the case of a resin containing fluorine, it is preferable to improve the adhesion by performing chemical treatment with tetraetch (main component: sodium naphthalene + dimethyl ether, manufactured by Junkosha Co., Ltd.) to form irregularities.

The resin having a glass transition temperature of −20 to 60 ° C., preferably 0 to 40 ° C., more preferably about 20 ° C. is suitable. As the resin, for example, polyurethane, polyvinyl chloride, ethylene vinyl acetate copolymer, polyamide,
Examples include polyamide elastomers and chlorinated polyethylene elastomers. X in the resin
A line contrast agent (eg, barium sulfate, bismuth oxide, bismuth subcarbonate, bismuth tungstate, etc.) may be present. When a resin having a glass transition temperature in the above range is used, the flexibility increases due to the body temperature after the insertion into the body, and the inner wall of the living body is less likely to be damaged.

Since the coil 11 is wound around the tube body 10, the strength of the tube body 10 is improved, the buckling of the tube can be prevented, and the torque transmissibility is improved. Moreover, since the braid body 12 is made of the same (or different) material and is wound around the tube body 10, the torque transmissibility is further improved as compared with the conventional tube provided with only the braid body.
Moreover, the X-ray contrast property can be improved by manufacturing the coil with a material such as a metal having an X-ray contrast property.

Therefore, the diameter of the tube itself can be reduced, and it is possible to provide a tube that is easy to insert and has good torque transmission.

The unevenness of 2 is reduced. Therefore, the surface of the heat-shrinkable coating layer 13 becomes smooth, and the insertion into the body can be performed smoothly. Also,
By filling the resin 14 and forming irregularities on the inner surface of the heat-shrinkable coating layer 13, the adhesion between the braided body 12 and the heat-shrinkable coating layer 13 is improved, and the heat-shrinkable coating layer 13 is not twisted.
Further, even if there are pinholes in the heat-shrinkable coating layer 13, blood or the like is blocked by the resin layer 14 and does not enter the tube.
