A surgical structure includes a solid, biologically compatible material that dissolves in a physiologically functioning vessel within a few hours or days. A surgical structure as detailed herein facilitates the joinder of vessels with tissue adhesives and other surgically acceptable closures and is formed of solid physiologic saline, block copolymers such as polyethylene glycol, polysaccharides, polymerized proteins such as collagen or gelatin, and synthetic polymers such as poly lactic acid or poly glycolic acid. A method of sealing a vessel includes inserting a solid biologically compatible material surgical structure having an extending portion and an intersecting portion having two arms into an aperture within a vessel such that the extending portion of the surgical structure has a fluid opening extending from the vessel aperture. The structure dissolves within the vessel within a few hours or days. A blunt end cut conduit is placed over the extending portion until the conduit end contacts the vessel proximal to the vessel aperture. With the introduction of a tissue sealant or other closure to the region of contact between the blunt end cut of the conduit and the vessel, the conduit and vessel are adhesively joined together.
