1. A device for connecting first and second tissue structures comprising:

  • first and second substantially parallel and elongate flexible segments each having proximal and distal ends, wherein the first and second segments each comprise a compliant material configured to be constricted for implantation within the first and second tissue structures, respectively, and wherein the material has a natural tendency to return to an unconstricted state such that, when implanted in the tissue structures, the material utilizes an internal fluid pressure within the respective tissue structure to conform to a shape of an inner surface of the tissue structure to provide a sealing contact with the inner surface; and

    a flow opening extending between the first and second segments at a point along the elongate length of the segments at least a distance from each of the proximal and distal ends to fluidically couple the first and second tissue structures.
