The techniques of this disclosure generally relate to a modular assembly including first and second stent-grafts. The first stent-graft includes a body portion having a first diameter and a waist portion having a second diameter less than the first diameter. The waist portion is at a distal end of the first stent-graft. The second stent-graft includes a captured proximal portion configured to be located within the first stent-graft. The captured proximal portion includes a seated portion configured to be located proximal to the waist portion. The seated portion has a third diameter greater than the second diameter to form a mechanical interlock between the first stent-graft and the second stent-graft.

Branching stent graft with mechanical interlock

Methods, systems, devices and apparatuses to support the walls of one or more blood vessels and perfuse blood through the one or more blood vessels. The stent device allows perfusion through one or more vessels. The stent device includes a tubular member. The tubular member has a single body that includes a main body lumen, a bypass lumen and one or more branch lumens. The tubular member is configured to be inserted into the aorta. The main body lumen is configured to expand and support a vessel wall of the aorta and the one or more branch lumens are configured to connect to one or more extension grafts that extend within one or more branch vessels. The stent device includes multiple rings of stents. The multiple rings of stents are positioned within the tubular member and are configured to be expandable to expand the tubular member to support the tubular member against the vessel walls.
