Abstract
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.
