    Abstract: A stent graft and a stent graft system having a scallop at the proximal end of the stent graft and extending below the proximal edge, the scallop having two substantially longitudinally extending opposing side edges and a substantially laterally extending bottom edge parallel to the proximal edge of the stent graft and extending between the two substantially longitudinally extending opposing side edges to define a scallop parameter. The stent graft and stent graft system include side arms extending externally from the stent graft at an acute angle to the body of the stent graft with an open end of the side arms extending toward the proximal end of the stent graft.

    Abstract: Various stents and stent-graft systems for treatment of medical conditions are disclosed. In one embodiment, an exemplary stent-graft system may be used for endovascular treatment of a thoracic aortic aneurysm. The stent-graft system may comprise proximal and distal components, each comprising a graft having proximal and distal ends, where upon deployment the proximal and distal components at least partially overlap with one another to provide a fluid passageway therebetween. The proximal component may comprise a proximal stent having a plurality of proximal and distal apices connected by a plurality of generally straight portions, where a radius of curvature of at least one of the proximal apices may be greater than the radius of curvature of at least one of the distal apices. The distal component may comprise a proximal z-stent coupled to the graft, where the proximal end of the graft comprises at least scallop formed therein that generally follows the shape of the proximal z-stent. Further, the distal component may comprise at least one z-stent stent coupled to the distal end of the graft and extending distally therefrom that reduces proximal migration of the distal component.
