摘要： The techniques of this disclosure generally relate to a modular stent device that is deployed into the ascending aorta via femoral access. The modular stent device is a base or anchor component to which additional modular stent devices can be attached to exclude diseased areas of the aorta while at the same time allowing perfusion of the brachiocephalic artery, the left common carotid artery, and/or the left subclavian 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 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： 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： Systems and methods for building a landing zone for an endovascular procedure are described. This procedure is “hybrid” in that it involves both direct access (e.g., sternotomy or partial sternotomy) to the site for installation of the landing zone, as well as endovascular installation of a TAVR or TEVAR device (e.g., stent graft) once the landing zone is installed. The landing zone is installed by wrapping a landing band around a portion of a vessel. The landing band may be selected to be fixed at a diameter so that it inhibits any expansion of the vessel, and also supports a later-installed TAVR or TEVAR device. The TAVR or TEVAR device is then endovascularly delivered to the vessel and deployed therein. The device expands until it contacts the vessel, which is supported from the outside by the landing band, which thus constrains and supports the device from outside.

摘要： The techniques of this disclosure generally relate to a stent-graft system including a bifurcated stent-graft, a first bifurcating branch device, and a first branch extension. The bifurcated stent-graft includes a body, a first branch limb, and a second branch limb. The first bifurcating branch device includes a body segment coupled to the first branch limb of the bifurcated stent-graft, a first branch limb, and a second branch limb. The first branch extension is within the first branch limb of the first bifurcating branch device and within an external iliac artery. The first bifurcating branch device has a wide patient applicability since the treatment can be extended proximal to the anatomical iliac bifurcation and is not limited by the common iliac artery length. The stent-graft system is suitable to treat a wide range of internal and external iliac artery diameters.
