Abstract: The techniques of this disclosure generally relate to a modular stent device including a main body configured to be deployed in the ascending aorta, a bypass gate configured to be deployed in the aorta, and a bifurcated contra limb. The bifurcated contra limb includes a single proximal limb that is bifurcated (split) into a first distal limb and a second distal limb. By forming the bifurcated contra limb to include a single proximal limb that is bifurcated into the distal limbs, guiding a guide wire into the relatively larger opening of bifurcated contra limb at a proximal end is simpler than guiding a guidewire into two smaller limbs extending distally from main body. Accordingly, cannulation of the bifurcated contra limb is relatively simple thus simplifying the procedure. In addition, the parallel design mimics anatomical blood vessel bifurcations to limit flow disruptions.

Abstract: 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.

Abstract: The techniques of this disclosure generally relate to an assembly including a docking graft. The docking graft includes a main graft defining a main lumen, a first internal lumen within the main lumen, a second internal lumen within the main lumen, and a main docking lumen within the main lumen. The first and second internal lumens are configured to receive first and second bridging stent graft therein. The main docking lumen is configured to receive a tube graft therein. The first internal lumen, the second internal lumen, and the main docking lumen being parallel to one another and extending an entire length of the docking graft when the docking graft is in a relaxed configuration. The docking graft forms the foundation, or anchor device, for attachment of the first bridging stent graft, the second bridging stent graft, and the tube graft within the aorta.

Abstract: 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.

Abstract: The techniques of this disclosure generally relate to an assembly including a single branch stent device and a modular stent device configured to be coupled to the single branch stent device. The single branch stent device includes a main body and a branch coupling extending radially from the main body. The modular stent device includes a main body configured to be coupled inside of the main body of the single branch stent device, a bypass gate extending distally from a distal end of the main body of the modular stent device, and an artery leg extending distally from the distal end of the main body of the modular stent device.

Abstract: 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.

Abstract: The techniques of this disclosure generally relate to a modular stent device that is deployed via supra aortic access through the brachiocephalic artery. 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 left common carotid artery and the left subclavian artery.

Abstract: 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.
