<P>PROBLEM TO BE SOLVED: To provide a production method of a medical porous body which is made of a high polymer without using a freeze-drying apparatus. <P>SOLUTION: This production method is that a high polymer solution is produced by dissolving the high polymer which is a material for the medical porous body in a solvent. The high polymer solution is mixed with a material to form holes and poured in a mold with a desired shape to be frozen in a freezing chamber so that a frozen body of the high polymer solution is obtained. Afterwards, an extraction solvent in which the high polymer in the frozen body is hardly or not soluble, and the solvent and the material to form the holes are soluble is used to extract the solvent from the frozen body. Finally, the extraction solvent which is included in the porous body is removed by drying. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
