Abstract

Abstract Connectors are provided for attaching flexible tubular grafts to the body organ tubing of a patient at oblique angles. The connector structures may be formed from two elongated members connected by a series of struts. Wire hooks welded to the connector may be used to engage the graft and the body organ tubing when the connector is used to attach the graft to the body organ tubing. The struts are bendable so that the elongated members can be compressed toward each other when it is desired to install a graft by placing the graft and the connector in a delivery tube. When the connector and graft are released from the delivery tube at the installation site, at least the open end of the connector adjacent to the body organ tubing has an oval shape for insertion into and attachment to an oval aperture in the body organ tubing. The elongated members are longitudinally shifted relative to each other so that the connector is angled obliquely to support attachment of the graft to the body organ tubing at an oblique angle.
