Abstract An elongated medical device 1 comprising a base material 11, a base layer 12, and a top layer 13, wherein the top layer 13 is formed from a polymer material in which a copolymer including a polymer unit with a hydrophilic structure is cross-linked with one of (1) -CH(OH)-CH(R1)-O-C(=O)-NH-R2-NH-C(=O)-OCH(R1)-CH(OH)-, (2) -CH(OH)-CH(R1)-O-C(=O)-NH-R2-NH-C(=O)-OCH(CH(R1)-OH)-, and (3) -CH(CH(R1)-OH)-O-C(=O)-NH-R2-NH-C(=O)-OCH(CH(R1)-OH)-, the base layer 12 is formed from an isocyanate compound, and the isocyanate compound is bonded with the structures of formulas (1) to (3). The elongated medical device exhibits excellent lubricity and excellent adhesion between the base material and a coating. Un dispositif médical allongé 1 comprenant un matériau de base 11, une couche de base 12 et une couche supérieure 13, la couche supérieure 13 étant formée à partir d'un matériau polymère dans lequel un copolymère comprenant une unité polymère ayant une structure hydrophile est réticulé avec l'un de (1) -CH(OH)-CH(R1)-O-C(=O)-NH-R2-NH-C(=O)-OCH(R1)-CH(OH)-, (2) -CH(OH)-CH(R1)-O-C(=O)-NH-R2-NH-C(=O)-OCH(CH(R1)-OH)-, et (3) -CH(CH(R1)-OH)-O-C(=O)-NH-R2-NH-C(=O)-OCH(CH(R1)-OH)-, la couche de base 12 est formée à partir d'un composé isocyanate, et le composé isocyanate est lié aux structures des formules (1) à (3). Le dispositif médical allongé présente un excellent pouvoir lubrifiant et une excellente adhérence entre le matériau de base et un revêtement. 基材11とベース層12とトップ層13とを備えた長尺状医療機器1であって、トップ層13が、親水性構造を有する重合単位を含有する共重合体が -CH(OH)-CH(R1)-O-C(=O)-NH-R2-NH-C(=O)-OCH(R1)-CH(OH)- ...(1) -CH(OH)-CH(R1)-O-C(=O)-NH-R2-NH-C(=O)-OCH(CH(R1)-OH)- ...(2) -CH(CH(R1)-OH)-O-C(=O)-NH-R2-NH-C(=O)-OCH(CH(R1)-OH)- ...(3) の何れかで架橋された高分子材料で構成され、ベース層12がイソシアネート化合物で構成され、イソシアネート化合物が式(1)~(3)の構造と結合した長尺状医療機器1。かかる長尺状医療機器は、優れた潤滑性を示すとともに、基材と被膜との間の密着性に優れる。
