Abstract: Methods and apparatuses to place a prosthesis within a receiving structure are provided. A delivery apparatus includes an elongated support member including a support member distal end. A stop cap is disposed at the support member distal end and includes a stop cap transverse dimension larger than an inner diameter of a receiving lumen of the receiving structure. An elongated prosthesis-positioning member extends along the support member and stop cap so a distal surface of the prosthesis-positioning member is disposed at a position longitudinally coincident with a portion of the stop cap. A sheath comprises a sheath lumen receiving the prosthesis-positioning member so the sheath translates longitudinally relative to the prosthesis-positioning member. The delivery apparatus has a loaded configuration in which the prosthesis is received in the sheath lumen with a proximal end of the prosthesis abutting the prosthesis-positioning member distal surface.

Abstract: Systems and methods to place a prosthesis to have a preselected overlap with a receiving structure are provided. In one embodiment, a delivery system may include a primary sheath comprising a primary sheath lumen. The delivery system may further include a secondary sheath comprising a secondary sheath lumen. The primary sheath may be at least partially received within the secondary sheath lumen such that the primary sheath may translate longitudinally within the secondary sheath lumen. The delivery system may further include a prosthesis having proximal and distal ends and being received within the primary sheath lumen adjacent to the primary sheath distal end in a contracted delivery state. The delivery system may further include a length reference mechanism that indicates a length of the primary sheath distal end that extends distal to the secondary sheath distal end during the contracted delivery state of the prosthesis.

Abstract: A pre-loaded delivery device that facilitates accurate placement of a stent graft assembly in the aorta is disclosed. A stent graft is carried on the delivery device and held in a pre-deployment configuration by a sheath. A split in the sheath facilitates the pre-cannulation of one or more branch arteries extending from the aorta before the stent graft is fully released in the aorta. The stent graft comprises a tubular body having at least one scalloped fenestration formed in one end of the graft material and at least one fenestration formed in the graft material of the main tubular body. A helical internal side branch extends from the fenestration within the lumen of the main tubular body. The helical side branch is configured to curve at least partially around the scalloped fenestration. The assembly further comprises a connection stent graft extending from the fenestration into a branch vessel.
Abstract translation: 公开了一种促进支架移植物组件在主动脉中的准确放置的预加载递送装置。 支架移植物携带在输送装置上并通过护套保持在预部署构型中。 护套内的分裂有助于在支架移植物完全释放于主动脉之前从主动脉延伸的一个或多个分支动脉的预插管。 支架移植物包括管状体,其具有形成在移植材料的一端中的至少一个扇形开窗和在主管状体的移植材料中形成的至少一个开窗。 螺旋内侧分支从主管体的内腔中的开窗延伸。 螺旋侧分支被配置成至少部分地围绕扇形开窗曲线。 组件还包括从开窗延伸到分支容器中的连接支架移植物。
