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: 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: 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: A prosthesis includes a first wire bent into a first waveform and spirally wrapped into a first helix having a plurality of windings that form a hollow cylindrical shape and a second wire bent into a second waveform and spirally wrapped into a second helix having a plurality of windings that form a hollow cylindrical shape. The first and second wires are disposed relative to each other such that the plurality of windings of the first wire and the plurality of windings of the second wire are disposed about a common longitudinal axis and the plurality of windings of the first wire and the plurality of windings of the second wire are axially offset from each other, with windings of the plurality of windings of the first wire alternating or interwoven between windings of the plurality of windings of the second wire along a length of the prosthesis.

Abstract: A venous valve prosthesis includes a frame and a prosthetic valve coupled to the frame. With the venous valve prosthesis implanted in a vein, the prosthetic valve includes a closed configuration wherein an outer surface of the prosthetic valve is in contact with a wall of the vein around a circumference of the prosthetic valve to prevent blood from flowing past the prosthetic valve between the wall of the vein and the outer surface of the prosthetic valve. The prosthetic valve is configured to move to an open configuration such that at least a portion of an outer wall of the prosthetic valve partially collapses away from the wall of the vein in response to antegrade blood flow through the vein to enable blood flow between the outer surface of the prosthetic valve and the wall of the vein.
