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.

Aortic repair devices and associated systems and methods are disclosed herein. An aortic repair device configured in accordance with embodiments of the present technology can include a base member configured to be implanted in an aorta proximate to a diseased portion of the aorta, such as an aneurysm or dissection. The base member can direct blood flow past the diseased portion of the aorta to perfuse a portion of the aorta distal of the diseased portion and/or various branch vessels. In some embodiments, one or more spanning members or other implants can be coupled (e.g., docked) to the base member during the same or a separate intravascular procedure to provide additional flow paths past the diseased portion.

A device for treating disease along a main vessel and at least one branch vessel extending from the main vessel includes a branch member for deployment in the branch vessel, the branch member having a branch lumen; and a main body for deployment in the main vessel. The main body has a generally tubular wall extending generally longitudinally between opposite first and second ends. The wall has an internal surface defining a main lumen and an opposite outer surface. The wall has a recessed portion that is recessed relative to the outer surface of the wall and positioned between the first and second ends of the main body. The main body has an opening formed in the recessed portion of the wall for receiving the branch member therethrough such that the branch lumen is in fluid communication with the main lumen.

An endovascular stent graft. The endovascular stent graft includes a body including a gate having an internal surface, a joining liner joined to the internal surface of the gate with a joint and having a bunched state and a crumpled state, and an implant at least partially disposed within the joining liner and having a radially compressed state and a radially expanded state. The implant in the radially expanded state exerts a radial force on the joining liner to maintain the joining liner in the crumpled state.

Bifurcated endovascular prostheses used to treat diseased blood vessels, such as arteries, are disclosed. In some embodiments, the bifurcated endovascular prosthesis is configured to be implanted within the diseased blood vessels adjacent a diseased section. The bifurcated endovascular prosthesis includes a primary stent graft and a secondary stent graft. The primary stent graft includes a pocket or sleeve disposed within a bore. A proximal portion of the secondary stent graft is disposed within the pocket or sleeve. Blood flow through the bifurcated endovascular prosthesis is divided into two flows, a first flow through the primary stent graft and a second flow through the secondary stent graft.

A transcatheter valve assembly replacement device includes a paravalvular seal that includes outwardly extending fibers that create a seal with the annulus when the valve assembly is deployed. An inwardly extending seal is attached to an outer frame. The inwardly extending seal is engaged with prosthetic valve leaflets.

A prosthetic component for repair of a patient's aorta includes an uncovered portion spanning the innominate arteries, and a graft material on a proximal end thereof.

A prosthetic component for repair of a patient's aorta includes an uncovered portion spanning the innominate arteries, and a graft material on a proximal end thereof.

The present invention relates to an endoluminal stent and an endoluminal stent system, with the endoluminal stent being delivered to a site at which it is to be implanted by means of a delivery device comprising a sheath for receiving the endoluminal stent. The endoluminal stent comprises a hollow tube body portion, a connection portion and a flange portion, wherein the tube body portion is connected to one end of the connection portion, the flange portion has a connection end and a suspended end opposite one another, with the connection end being connected to the other end of the connection portion in a turning connection, and the suspended end being suspended, the flange portion comprising a flange section bare wave ring made of an elastic material; the suspended end is located at a distal side of the connection end when the endoluminal stent is in a natural state; the suspended end is located at a proximal side of the connection end when the endoluminal stent is received in the sheath; and after the flange portion is released from the sheath, the flange portion automatically turns over, and the suspended end moves from the proximal side of the connection end to the distal side of the connection end. The endoluminal stent of the present invention can enhance the anchoring force thereof.

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.
