ENDOGRAFT

摘要

An endograft deployment mechanism (100) having a cone (104) for placement in a blood vessel (220), a plurality of struts (107) having first ends (108) engaged with the cone (104) and second ends (109) opposite the first ends (110), and a hollow outer sheath (101) associated with the cone (119), the sheath (101) housing an endograft (11) having proximal (112) and distal ends, wherein the second ends (109) of the struts (107) are removably attached to the proximal end (112) of the endograft (111) such that the endograft (111) may be separated from the struts (107) during deployment thereof. An endograft (111) having a trunk portion (125) with an end, a first branch (113) extending from the junction to an end, a second branch (114) extending from the junction to an end, and a plurality of integral hoops disposed only within the ends, making the ends circumf erentially radiopaque. An endograft (111') may also include a stent (250') adjacent to the junction to ensure fluid communication between the trunk (125') and branches (113'), (114') and opening of the bifurcation.
