An exemplary embodiment may comprise a sidewall port, such as a flanged sidewall port, and/or flow frame design, such as a partially bare, flexible stent or a whisk, for purposes of creating a transmural flow. Another exemplary embodiment may comprise a compliant vessel support to aid in the transition from device to vessel and/or vessel to device, and to promote vessel dilation. ## Claims ### Claim 1 A stent graft comprising: a sidewall port device configured for coupling the stent graft to an aperture in a tissue wall; and a conduit configured to extend through the aperture in the tissue wall for transporting fluid when implanted, the side wall port device comprising a lattice inverted onto itself to form an inner tube disposed coaxially within an outer tube. ### Claim 2 (depends on 1) The stent graft of claim 1, wherein the sidewall port device comprises dual flanges extending radially outwardly with respect to the aperture, the flanges being configured for mechanically engaging opposite sides of the tissue wall for fixedly securing the stent graft to the tissue wall. ### Claim 3 (depends on 2) The stent graft of claim 2, wherein the dual flanges are lined at least partially by a flexible film. ### Claim 4 (depends on 3) The stent graft of claim 3, wherein the film is ePTFE. ### Claim 5 (depends on 2) The stent graft of claim 2, wherein the dual flanges include a braided wire frame. ### Claim 6 (depends on 2) The stent graft of claim 2, wherein one of the dual flanges provides a transition between the inner tube and outer tube. ### Claim 7 (depends on 1) The stent graft of claim 1, wherein the sidewall port device is configured for coupling the stent graft to the aperture in the tissue wall, wherein the aperture is surgically made. ### Claim 8 (depends on 1) The stent graft of claim 1, wherein the sidewall port device is configured for coupling the stent graft to the aperture in the tissue wall, wherein the aperture is endovascularly-made. ### Claim 9 (depends on 1) The stent graft of claim 1, wherein the conduit is coupled to the sidewall port device. ### Claim 10 (depends on 1) The stent graft of claim 1, wherein the conduit is an extension of the inner tube. ### Claim 11 (depends on 1) The stent graft of claim 1, wherein the conduit is an extension of the outer tube. ### Claim 12 (depends on 1) The stent graft of claim 1, wherein the conduit provides for transporting fluid from a first vessel to a second vessel. ### Claim 13 A medical device comprising: a first conduit portion configured to transport a fluid within a vessel; a second conduit portion in fluid communication with the first conduit portion and configured to transport fluid through an aperture in the vessel; and a sidewall port device coupled to the second conduit portion, the sidewall port device comprising a lattice inverted onto itself to form an inner tube disposed coaxially within an outer tube. ### Claim 14 (depends on 13) The medical device of claim 13, wherein the vessel is a first vessel and wherein the sidewall port device is configured to couple to an aperture in a vessel wall of the second vessel. ### Claim 15 (depends on 14) The medical device of claim 14, wherein the first conduit portion, the second conduit portion, and the sidewall port device are configured to transport fluid from the second vessel to the first vessel. ### Claim 16 (depends on 14) The medical device of claim 14, wherein the sidewall port device comprises dual flanges configured for mechanically engaging the sidewall port device to the second vessel. ### Claim 17 (depends on 16) The medical device of claim 16, wherein the dual flanges of the sidewall port device extend radially outwardly with respect to the aperture in the vessel wall of the second vessel. ### Claim 18 (depends on 14) The medical device of claim 14, wherein the sidewall port device comprises dual flanges configured to engage opposite sides of the vessel wall of the second vessel for securing the sidewall port device to the second vessel. ### Claim 19 A medical device comprising: a conduit portion configured to transport a fluid from a first vessel into a second vessel; and a sidewall port device coupled to the conduit portion and to the first vessel, the sidewall port device comprising a lattice inverted onto itself to form an inner tube disposed coaxially within an outer tube. ### Claim 20 (depends on 19) The medical device of claim 19, wherein the sidewall port device comprises dual flanges extending radially outwardly with respect to an aperture in a vessel wall of the first vessel, the flanges being configured for mechanically engaging generally opposite sides of the vessel wall of the first vessel. ### Claim 21 (depends on 20) The medical device of claim 20, wherein the dual flanges are lined at least partially by a flexible film. ### Claim 22 (depends on 21) The medical device of claim 21, wherein the film is ePTFE. ### Claim 23 (depends on 20) The medical device of claim 20, wherein the dual flanges include a braided wire frame. ### Claim 24 (depends on 20) The medical device of claim 20, wherein one of the flanges of the dual flanges provides a transition between the inner tube and outer tube.
