PROBLEM TO BE SOLVED: To effectively suppress an increase in internal pressure of an aneurysm and reduce an influence on surrounding tissue.SOLUTION: An aneurysm treatment device 10 treats an aneurysm 102 which includes a reservoir region 104 in which blood flows, and a neck region 106 connecting the reservoir region 104 and a blood vessel 100 with each other. The aneurysm treatment device 10 includes: a shaft 12 which is delivered through the blood vessel 100, and the tip end of which is inserted into the neck region 106 a suction port 20 which can suck the blood flowing into the aneurysm 102, via a suction lumen 16 for allowing the shaft 12 to communicate in an axial direction and a closing member 28 which is detachably attached to the shaft 12 and which is retained in the neck region 106 when disengaged from the shaft 12.COPYRIGHT: (C)2013,JPO&INPIT【課題】瘤内圧の上昇を効果的に抑制することができ且つ周辺組織への影響を低減する。【解決手段】瘤治療デバイス10は、血液が流入される溜り部104と、溜り部104と血管100を連通させる頸部106とからなる瘤102を治療する。この瘤治療デバイス10は、血管100内を通して送達され、その先端部が頸部106に挿入されるシャフト12と、シャフト12を軸方向に連通する吸引ルーメン16を介して瘤102に流入された血液を吸引可能な吸引口20と、シャフト12に対し着脱自在に取り付けられ、シャフト12から離脱されることで頸部106に留置される閉塞部材28と、を備える。【選択図】図1
