Covered medical devices and their manufacturing methods

Abstract

The purpose of this invention is to provide a coated medical device that, in addition to providing sufficient hydrophilicity and slip resistance, also provides lipid adhesion inhibition, and a simple method for manufacturing the same. This invention provides a coated medical device and a method for manufacturing the same. The coated medical device includes a medical device and a hydrophilic polymer layer covering the surface of the medical device. The hydrophilic polymer layer comprises a hydrophilic polymer A, which contains a compound a1 having a specific structure and a compound a2 having amide groups as monomer units. The copolymerization ratio of compound a1 to compound a2 is 1 / 99 to 99 / 1 by mass.
