Abstract: The techniques of this disclosure generally relate to modular stent device and method of deploying the same. The method includes introducing a delivery system including the modular stent device via supra aortic access. The delivery system is advanced into the ascending aorta. Once positioned, the modular stent device is deployed from the delivery system such that an artery leg of the modular stent device engages the brachiocephalic artery and a bypass gate engages the aorta, wherein the artery leg partially collapses the bypass gate. The artery leg has a greater radial force than the bypass gate such that the artery leg remains un-collapsed and opened. Accordingly, blood flow through the artery leg and perfusion of the brachiocephalic artery and preservation of blood flow to cerebral territories including the brain is insured.

Abstract: 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 stent-graft system is suitable to treat a wide range of internal and external iliac artery diameters.

Abstract: 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.

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.
