Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 芯線の外周に合成樹脂膜を被覆し、この合成 樹脂膜の表面に親水性被膜を形成したガイドワイヤーに おいて、繰り返し使用しても潤滑性が低下しないように したガイドワイヤー及びその製造法を提供する。 【構成】 芯線1の外周に、ポリエーテルブロックアミ ドからなる合成樹脂膜2を被覆する。この合成樹脂膜2 の表面にイソシアネート基を2つ以上有する化合物を結 合させて、未反応のイソシアネート基を形成する。更 に、ポリビニルピロリドンを反応させて、合成樹脂膜2 の表面にイソシアネート基を介してポリビニルピロリド ンを結合させて、親水性被膜3を形成する。好ましく は、重合開始剤の存在下でポリビニルピロリドンを反応 させ、ポリビニルピロリドン分子を相互に重合させる。 (57) [Abstract] [Purpose] A synthetic resin film was coated on the outer periphery of the core wire, and a guide wire with a hydrophilic coating formed on the surface of the synthetic resin film was designed so that lubricity would not deteriorate even after repeated use. A guide wire and a manufacturing method thereof are provided. [Structure] The outer periphery of the core wire 1 is coated with a synthetic resin film 2 made of polyether block amide. This synthetic resin film 2 A compound having two or more isocyanate groups is bonded to the surface of to form an unreacted isocyanate group. Further, by reacting polyvinylpyrrolidone, the synthetic resin film 2 Polyvinylpyrrolidone is bonded to the surface of the via an isocyanate group to form the hydrophilic coating 3. Preferably, polyvinylpyrrolidone is reacted in the presence of a polymerization initiator to polymerize polyvinylpyrrolidone molecules with each other.
