POROUS BIOABSORBABLE MATERIAL AND METHOD OF PRODUCING THE SAME

摘要

[PROBLEMS] To provide a porous bioabsorbable material in the shape of a film which is a dense construct having a small average pore size and an even pore size and showing a large maximum stress, in particular, a porous bioabsorbable material which is highly useful as a material for preventing adhesion. [MEANS FOR SOLVING PROBLEMS] A porous bioabsorbable material characterized by comprising a bioabsorbable polymer which is constructed by gelling a bioabsorbable polymer by using a good solvent compatible with the bioabsorbable polymer and a poor solvent and freeze drying the thus gelled bioabsorbable polymer to give a porous structure; and a method of producing a porous bioabsorbable material characterized by comprising gelling a bioabsorbable polymer by using a solvent mixture composed of a good solvent compatible with the bioabsorbable polymer and a poor solvent and freeze drying the gelled product thus gelled to give a porous structure.
