BIOCOMPATIBLE MATERIAL, MEDICAL INSTRUMENT AND METHOD FOR USING MEDICAL INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To provide a biocompatible material excellent in antithrombogenic property, a medical instrument and a method for using a biocompatible material.

SOLUTION: The biocompatible material contains a mixture of a polymer which maintains a glassy mixed phase with polyacrylic acid 2-methoxyethyl in a room temperature and the polyacrylic acid 2-methoxyethyl. Here, a ratio of the polyacrylic acid 2-methoxyethyl to polymethyl methacrylate as a mixed weight ratio of the polymethyl methacrylate to the polyacrylic acid 2-methoxyethyl in the mixture is within a range of 1:99-90:10. The mixture has an inclined structure in which the polyacrylic acid 2-methoxyethyl is segregated on a surface side.
