Provided are a polymer which, when wetted, enables a medical apparatus for use in MRI diagnosis and therapy to be easily visible under MRI and, simultaneously, develops surface lubricity, and a medical apparatus coated with the polymer. The polymer including a copolymer composed of a substance for shortening relaxation time of a nuclear species capable of being detected by magnetic resonance, a moiety having a reactive group, and a moiety for developing lubricity is used to coat the medical apparatus, whereby excellent peel resistance, high lubricity, visibility under magnetic resonance, easy applicability, and high safety can be obtained.
提供了一种聚合物,当它被润湿时,可以使用于MRI诊断和治疗的医疗器械在MRI下易于观察,并同时具有表面润滑性,以及用该聚合物涂覆的医疗器械。该聚合物包括由一种缩短核物种弛豫时间的物质、具有反应性基团的基团和用于发展润滑性的基团组成的共聚物,用于涂覆医疗器械,可以获得优异的剥离抗力、高润滑性、MRI下的可见性、易于应用和高安全性。
