Abstract
One aspect of the present disclosure can include a frame structure adapted for use with a stent graft. The frame structure can include a scallop region and a Z-form region. The scallop region can have a first end portion, a second end portion, and a perimeter that defines an aperture. The Z-form region can extend from the scallop region and include a plurality of Z-shaped struts, each of which has a first end and a second end that is connected to the scallop region at different points so as to form a central frame structure lumen. The second end portion of the scallop region can include a backstop that is deployable from a first flattened configuration to a second erect configuration. The backstop, in the second erect configuration, is sized and dimensioned to extend into a lumen of an aortic branch vessel.
