Title: COPOLYMER, ANTITHROMBOTIC COATING AGENT USING SAME AND MEDICAL DEVICE
Abstract:
The objectives of the present invention are: to find a biocompatible material which has excellent film formation properties and resistance to water dissolution and is able to be easily coated to various bases, while having excellent antithrombotic properties; and to provide an antithrombotic coating agent and an antithrombotic coating film, each of which uses this biocompatible material, and a medical device which is provided with this antithrombotic coating film. Means that have enabled the achievement of these objectives are: a copolymer which contains at least one repeating unit (A) represented by formula (1) and at least one repeating unit (B) represented by formula (2); an antithrombotic coating agent which contains this copolymer and an organic solvent; an antithrombotic coating film which is formed of this copolymer; and a medical device which is provided with this coating film. (In formula (1), n represents an integer of 2-10; and R1 represents a methyl group or an ethyl group.) (In formula (2), R2 represents an aliphatic hydrocarbon group.)
