BRANCH STENT RETENTION CUFF

The present embodiments describe an endograft having at least one fenestration, at least one cuff support structure, and at least one branch stent, and methods for deploying the same. In one example, the system comprises a branch stent within the cuff support structure, where upon expansion of the branch stent, the cuff support structure expands from a first state to a second state and has a radially inward bias towards the smaller first state. In another example, the system comprises a cuff support structure having at least one barb, where the barb is flush with the cuff support structure in a first state, and where upon expansion of the cuff support structure to a second state, the barb deflects radially inward. Both the radially inward bias of the cuff and radially inward deflection of the barb may facilitate an interference fit between the cuff and the branch stent.
