Patent ID: 8246672

Claim:
A device for repairing a vessel of a body, comprising: a tubular graft having a proximal end, a distal end, and a lumen therethrough, the graft having a collapsed configuration for delivery into the vessel and an expanded configuration for at least partially engaging the vessel, where the graft comprises a biocompatible material capable of incorporation into the vessel wall; a plurality of distinct and independently insertable, positionable, and expandable frame units removably disposed within the lumen of the tubular graft, each frame unit having an expanded configuration and a collapsed configuration, a proximal end and a distal end, where each frame unit extends from a hub defined by a longitudinal axis and comprises a plurality of expandable members, and at least a portion of the expandable members in the expanded configuration contacts a distinct portion of an inner surface of the tubular graft to expand that portion of the graft and wherein at least one of the plurality of expandable members has a convex curve towards the longitudinal axis followed by a concave curve away from the longitudinal axis; and where each frame unit is collapsible and repositionable within the tubular graft or collapsible and removable from the tubular graft.
