1. 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.

Abstract
A device for repairing a vessel body including a plurality distinct and independently positionable, expandable frame units disposed within a tubular graft. The independent frame units are capable of being positioned, repositioned, or removed to conform the tubular graft to the anatomy of the vessel body.

7. A device for repairing a vessel of a body, comprising:
-
a tubular graft having a proximal end, a distal end, and a lumen therethrough, 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 to permanently engage the vessel wall; a plurality of distinct and independently insertable, positionable, and expandable frame units capable of being independently positioned in, repositioned within, or removed from the tubular graft, where each frame unit comprises, an expanded configuration and a collapsed configuration; a distal end; a hub at the distal end; and a plurality of expandable members having a first end secured by the hub, the plurality of expandable members extending from hub, each member having a collapsed configuration for insertion into the vessel and for subsequent removal from the vessel and an expanded configuration where at least a portion of the expandable member contacts a distinct portion of an inner surface of the tubular graft to expand that portion of the graft. - View Dependent Claims (8, 9, 10, 11)
