1. A suture, comprising:
a set of legs having proximal ends joined to each other and elongate bodies that extend parallel to one another such that the set of legs form a U-shaped structure, the set of legs having distal ends that terminate in sharpened tips that are configured to penetrate through a portion of a graft and a vessel wall;
a tail coupled to the U-shaped structure,
the suture configured to transition from a flattened configuration in which the tail extends in a direction opposite to the direction of the elongate bodies of the set of legs to a curved configuration in which the tail and the set of legs are curved, the suture in the curved configuration being configured to form an annular loop with at least a portion of the tail being configured to be disposed within an outer perimeter of the annular loop when the suture is in the curved configuration,
the set of legs and the tail configured to exert forces in opposite directions when the suture is in the curved configuration such that the set of legs and the tail are configured to hold the portion of the graft and the vessel wall relative to one another.
