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.

A multi-lumen stent-graft including a graft portion and a stent frame. The stent-graft includes multiple through-channels formed of the graft portion. The graft portion can comprise a PTFE material and the through-channels can be formed of fused portions of the graft portion. The stent-graft can be used in a prostheses that connects multiple vessel branches such as for the repair of aortic aneurysms or other vessels of the body.

Devices, systems and methods of endoluminally delivering a modular endoprosthetic system in accordance with various embodiments are disclosed herein for treating disease of human vasculature. In various embodiments, the modular endoprosthetic system includes a plurality of expandable endoprosthesis components that are coupled together to define the modular endoprosthetic system, wherein the modular endoprosthetic system provides for retrograde perfusion of a branch vessel from a main vessel.

The presently disclosed subject matter is directed to a dual stent assembly useful in treating one or more bifurcation lesions in a subject. The dual stent assembly includes a first stent and a second stent. The first stent comprises a body, proximal and distal ends, and a flare positioned at the proximal end. The first stent translates between a compressed configuration and a deployed configuration. The second stent is defined by a body comprising a sidewall, proximal and distal ends, and an orifice positioned on the body that extends through the sidewall. The second stent is translatable between a compressed configuration and a deployed configuration. The orifice is sized and shaped to align with the proximal end of the first stent when the second stent is deployed.

Systems and methods for treating diseased bodily lumens involving branched lumen deployment sites include a main graft or stent-graft deployable in a main artery and a vent device or stent-graft deployable in a branch artery to maintain blood flow through the main artery and from the main artery to the branch artery. Systems and methods for treating diseased bodily lumens involving branched lumen deployment sites may also include a main graft or stent-graft deployable in the main artery, a chimney graft or stent-graft deployable in both branch artery and the main artery to the branch artery and a gutter-sealing device associated with the chimney graft to prevent flow of blood among the chimney graft, the main graft and a wall of the main artery.

A method of establishing an anastomosis utilizing a harvested blood vessel includes connecting the blood vessel to an artery, thereby forming an anastomosis therebetween. The method further includes wrapping an outer surface of the blood vessel with a tubular support. The tubular support exerts a radially-inward force on the blood vessel.

A method of treating an aortic aneurysm of a patient with an endovascular graft system and mitigating post implant syndrome associated therewith comprises placing at least one prosthesis across an aneurysmal space. The prosthesis comprises a double-walled filling structure and a stent-graft. The stent graft is radially expanded at a first pressure and the filing structure is filled with a first filing agent to contact a thrombus in the aortic aneurysmal space. After the first filling agent is removed, the filling structure is filled with a second filling agent to contact the thrombus. Next the stent-graft is expanded at a second pressure causing the filing structure to place an effective amount of pressure on the thrombus and substantially mitigating the effects of post implant syndrome associated with the prosthesis.

An iliac branch device has an external iliac body, a common iliac branch, and an internal iliac branch. A diameter of the proximal opening of the common iliac branch is greater than a diameter of a distal opening of the external iliac body. The iliac branch device is configured to be deployed without going up and over the aortic bifurcation and without using some form of supra-aortic antegrade access such as through brachial or axillary artery access. This simplifies the procedure and reduces procedure time thus maximizing the success rate of the procedure and allows the procedure to be performed on a broad patient population.

A stent (scaffold) or other luminal prosthesis comprising circumferential structural elements which provide high strength after deployment and allows for scaffold to uncage, and/or allow for scaffold or luminal expansion thereafter. The circumferential scaffold is typically formed from non-degradable material and will be modified to expand and/or uncage after deployment.

The present application discloses a covered stent and a method for navigating the covered stent to a branch vessel, the covered stent including a main body and at least one lateral side branch connected to the main body. A system of covered stents and a method for implanting, including interconnecting the covered stents is also disclosed.
