Patent ID: 8663309

Claim:
A method of securing at least one end of a stent-graft within an angulated vessel of a patient, comprising: positioning within the angulated vessel a stent-graft comprising: a tubular graft member comprising at least one longitudinal lumen configured to confine a flow of fluid therethrough, and a cylindrical stent including: a connection end of the stent connected to an end of the tubular graft member, a free end which is disposed axially opposite the connection end, a plurality of struts extending between the connection end and the free end, and a first pair of adjacent short struts diametrically opposed to a second pair of adjacent short struts, the short struts defining a distal most portion of the free end; a first pair of adjacent long struts diametrically opposed to a second pair of adjacent long struts, the long struts defining a proximal most portion of the free end with the pairs of long struts being circumferentially offset approximately ninety degrees relative to the pairs of short struts; positioning the stent-graft within the angulated vessel such that the cylindrical stent is disposed in an angulated portion of the angulated vessel; and deploying the cylindrical stent within the angulated vessel such that the first pair of adjacent short struts is aligned with an inner radial curvature of the angulated vessel, the second pair of adjacent short struts is aligned with an outer radial curvature of the vessel, the first pair and second pair of adjacent long struts are aligned along respective sides of the angulated vessel and no long struts are aligned with the inner radial curvature or an outer radial curvature of the angulated vessel.
