    摘要： A prosthetic assembly configured for endovascular placement within an aortic arch and method of use thereof. The prosthetic assembly includes a proximal aortic stent-graft prosthesis configured to be positioned within a proximal portion of the aortic arch adjacent to the brachiocephalic artery, a distal aortic stent-graft prosthesis configured to be positioned within a distal portion of the aortic arch adjacent to the left subclavian artery, a first branch stent-graft prosthesis configured to be positioned within the brachiocephalic artery and a second branch stent-graft prosthesis configured to be positioned in one of the left common carotid and the left subclavian artery. When deployed, a proximal end of the first branch stent-graft prosthesis is disposed within a lumen of the proximal aortic stent-graft prosthesis to proximally displace the ostium of the brachiocephalic artery. When deployed, a proximal end of the distal aortic stent-graft prosthesis is disposed within the distal end of the proximal aortic stent-graft prosthesis to form an overlap between the proximal and distal aortic stent-graft prostheses. The overlap is relatively increased by the first branch stent-graft prosthesis proximally displacing the ostium of the brachiocephalic artery.

    摘要： The techniques of this disclosure generally relate to an assembly including a single multibranch stent device. The single multibranch stent device includes a main body, a proximal coupling extending radially from the main body, and a distal coupling extending radially from the main body. The main body, the proximal coupling, and the distal coupling are permanently coupled to one another and the single multibranch stent device is a single piece. By forming the single multibranch stent device as a single piece, the single multibranch stent device can be deployed in a single deployment thus simplifying the deployment procedure.

    摘要： A stent-graft prosthesis for implantation within a body vessel includes a graft material, a frame, and a channel. The graft material includes a proximal end, a distal end, and a graft lumen extending between the proximal and distal ends. The frame is coupled to the graft material. The channel is configured to relieve pressure associated with pulsatile blood flow during implantation of the stent-graft prosthesis within a body vessel. The channel permits blood to flow from an upstream side of the stent-graft prosthesis to a downstream side of the stent-graft prosthesis when the stent-graft prosthesis is in a partially expanded configuration in the body vessel. The channel may be a plurality of channels.

    摘要： Embodiments hereof relate to a guidewire formed from an elongated shaft, at least a portion of the shaft having an outer layer, a plurality of channels formed through the outer layer, and an inner core. The outer layer is formed from a material non susceptible to erosion by an erosion agent and the inner core is formed from a radiopaque material susceptible to erosion by the erosion agent. When exposed to the erosion agent, core material adjacent to the channels is removed to form a pattern of integral radiopaque segments or markers with a plurality of voids therebetween. By controlling the location of channels and the rate of erosion of the core material, the pattern of integral radiopaque segments and voids allow for in situ measurement when viewed under fluoroscopy.

    摘要翻译： 本发明的实施方案涉及由细长轴形成的导丝，所述轴的至少一部分具有外层，穿过外层形成的多个通道和内芯。 外层由不易受侵蚀剂侵蚀的材料形成，内芯由易受腐蚀剂腐蚀的不透射线材料形成。 当暴露于侵蚀剂时，除去与通道相邻的芯材料以形成其间具有多个空隙的整体不透射线段或标记的图案。 通过控制通道的位置和芯材的侵蚀速率，整体不透射线段和空隙的图案允许在荧光透视下观察时的原位测量。
