Patent ID: 8535370

Claim:
A device for repairing a corporeal vessel, comprising: a graft having a wall defining a lumen; and a plurality of imagable markers, each having a substantially same size and shape, disposed on the graft in first and second sets, each marker of the first set of markers defining a first layout configuration and each marker of the second set of markers defining a second layout configuration circumferentially spaced from the first layout configuration, wherein a relative relationship between the first and second sets of markers indicates the rotational orientation of the graft inside the corporeal vessel, wherein the first set of markers is disposed on an anterior side of the graft and the second set of markers is disposed on a posterior side of the graft, wherein the first and second sets of markers are disposed along a first and a second line respectively, the first and second lines parallel to a longitudinal line of the graft, and wherein all of the markers of the first and second sets of markers form a single line of non-overlapping markers when the anterior and posterior sides of the graft are aligned in an internal lumen of the corporeal vessel.
