Abstract
Abstract Connector structures are provided for attaching elongated flexible tubular grafts to the body organ tubing of a patient. The connector structures are formed from wire. A first set of connector wires may be disposed around the periphery of one end of an elongated flexible tubular graft. A second set can be disposed around the periphery of the elongated flexible tubular graft spaced sufficiently from the first set of connector wires to define a gap. The portion of body organ tubing to which the elongated flexible tubular graft is to be attached is received in the gap and engaged by the first and second sets of connector wires. The wires may be formed in the shape of loops. If desired, hooks may be provided on the ends of the wires. The wires may be curved to accommodate attachment of the graft to tubular body organ tubing. The wires may also be formed in annular shapes. The connector structures may be formed as stand-along ring-shaped connectors. Obliquely-angled connections between grafts and body organ tubing may be made using the connector structures.
