Abstract:
1. An endovascular graft delivery system configured to deliver an endovascular graft to a target location within a patient's vasculature and deploy the endovascular graft at the target location, comprising: an endovascular graft comprising a proximal end, a distal end, a tubular graft body section disposed between the proximal end and the distal end, and a first distal self-expanding member that is disposed distally of: (i) a second self-expanding member and (ii) the distal end of the graft body section; wherein the first distal self-expanding member comprises a serpentine configuration having a plurality of struts and having a plurality of proximal and distal apices, and a barb integrally formed as an extension of each strut and extending outwardly from a position on each strut, wherein the barb has an elevation angle with respect to a longitudinal axis of a strut from which the barb extends of about 10 degrees to about 45 degrees; wherein the proximal apices are curved apices having an outer surface with a circular radius of curvature of between about 0.030 inch to about 0.070 inch; and a delivery system comprising: wherein the outer tubular member is configured to be retracted proximally to expose the graft body section; and wherein the release member is operable to release the constraint from the first distal self-expanding member after the outer tubular member is retracted proximally to at least partially expose the graft body section.
