The introducer assembly is configured to drive the restraining sheath 200 between a first state that releasably restrains the vascular graft and a second state that allows deployment of the vascular graft. A second for driving the blocking mechanism between the driving mechanism 320 and a blocking state for blocking other functions of the handle 300 and a non-blocking state for enabling operation of other functions of the handle 300. It is possible to operate both the first drive mechanism and the second drive mechanism for simultaneous operation of both the first drive mechanism 360 and the first drive mechanism and the second drive mechanism according to the drive of the operation handle. And an operation handle 330 coupled to.導入器アセンブリは、血管移植物を解放可能に拘束する第１の状態と、血管移植物の展開を可能とする第２の状態と、の間で拘束被覆部２００を駆動するための第１の駆動機構３２０と、ハンドル３００の他の機能を遮断するための遮断状態と、ハンドルの他の機能の操作を可能とするための非遮断状態と、の間で遮断機構を駆動するための第２の駆動機構３６０と、操作取っ手の駆動に応じた第１の駆動機構及び第２の駆動機構の両方の同時操作のために第１の駆動機構及び第２の駆動機構の両方に対して動作可能に結合された操作取っ手３３０と、を有する。
