Method for producing antithrombotic medical device

Abstract

The objective of the present invention is to provide a method for coating a polyurethane medical device such as a catheter with an antithrombotic material for antithromboticity with suppressing dimensional change such as swelling and shrinkage of the medical device. The method for producing an antithrombotic medical device according to the present invention is characterized in comprising the steps of dissolving an antithrombotic material comprising a (meth)acrylate copolymer in an aliphatic hydrocarbon solvent to prepare an aliphatic hydrocarbon solution, coating a medical device with the aliphatic hydrocarbon solution, and removing the aliphatic hydrocarbon solvent from a surface of the medical device, wherein the medical device is composed of polyurethane.
