< Topic >The device and method in order to remove organization are offered.SolutionsWith one feature, as for the device in order to remove organization, it extends from the component where the air which possesses the external wall and lumen is long and the component whose air is long, selective the development possible organizational cutting element and in lumen, we have extended, it connects to the component whose at the same time air is longer and narrower than the organizational cutting element at the distal (2036) place, the operation component and, it includes. Motion of the operation component can be developed, move the organizational cutting element to organizational cutting form, in order from the insertion form where the organizational cutting element is not developed, the organizational cutting element to extend to radial in comparison with insertion form.< Selective figure >Figure 1A【課題】組織を除去するための装置および方法を提供する。【解決手段】一態様では、組織を除去するための装置は、外壁および内腔を有する中空の細長い部材と、中空の細長い部材から延びる選択的に展開可能な組織切断要素と、内腔の中を延びており、かつ組織切断要素より遠位の場所で中空の細長い部材に連結する、作動部材と、を含む。作動部材の運動は、組織切断要素が展開されていない挿入形態から、組織切断要素が挿入形態と比べて半径方向に延びるように展開される、組織切断形態まで、組織切断要素を動かすことができる。【選択図】図1A
