| Outline of Final Research Achievements |
The purpose of this study is the development of MDP(multi detach point)coil for coil embolization of cerebral aneurysm.We made MDP prototype coil.MDP coil has 2 detach point.We used the electrically Detachable Coil and the mechanical detachable coil. The electrically Detachable Coil has detach point made by PVA(polyvinyl alcohol) .MDP prototype coil was made by these coils that were connected.
We performed experiment of detach system of MDP prototype coil by using Vascular model.There were no troubles in 2 detach point of MDP prototype coil.

| Academic Significance and Societal Importance of the Research Achievements |
瘤内塞栓術ではレアメタルであるplatinumを素材とした塞栓術用のcoilが使用されるが、現在流通しているcoilには必要な長さを自在に瘤内に離脱できるsystemがない。瘤内塞栓術中に使用し一度回収したcoilは、場合によってはその手術中に再利用されず医療資源の損失となりうる。またcoilの回収は手術時間の延長にも関与する。今回発案したmulti-detach point coil（MDP coil）には、医療経済に貢献しかつ瘤内塞栓術の成績向上に寄与する可能性があると考えられる。
