PROBLEM TO BE SOLVED: To provide an appliance for delivering a device to a hollow organ and a delivery method.SOLUTION: An appliance comprises a slender tube 12 which has a proximal opening and a distal opening and a device 15 attached to the distal portion. The appliance further comprises a tubular cover 24 for covering at least partially the device when the device is attached to the slender tube 12. The tubular cover 24 has elasticity in a radial direction and non-elasticity in an axial direction. The tubular cover 24 can be collected into the slender tube 12 from the distal opening, so that when the device 15 is attached to the slender tube 12 and covered by the tubular cover 24, the device 15 is exposed by collection of the tubular cover 24 into the slender tube 12, and the device is delivered into a hollow organ.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2020,JPO&INPIT【課題】デバイスを中空器官内に送達するための器具および送達方法を提供する。【解決手段】器具は、近位開口および遠位開口を有しその遠位部分にデバイス１５が装着されるように構成される細長い管１２を含む。器具は、さらに、細長い管１２に取り付けられるときにデバイスの少なくとも一部を覆う管状カバー２４を含む。管状カバー２４は、径方向に弾性を有し、軸方向に非弾性を有する。管状カバー２４は、遠位開口から細長い管１２内に回収可能であり、したがって、デバイス１５が細長い管１２に取り付けられ管状カバー２４によって覆われるとき、細長い管１２内への管状カバー２４の回収によりデバイス１５が露出されて中空器官内に送達される。【選択図】図３
