Outline of Final Research Achievements

Non-woven fabric bioabsorbable spacer consisted of surgical polyglucolic acid　(PGA)　sutures　has　been　originaly invented. Characteristics and safety was intensively examined,and animal studies were performed without severe toxicity. The ability of the PGA spacer is to keep its thickness more than 85% for 8 weeks. The spacer reduced gradually, however, it did not cause any toxicity. Clinical study has been started to elucidate efficacy and safety of this spacer for particle therapy
