An implantable flow connector for fluidically coupling a source tissue-enclosed body space with a destination element, comprising: a conduit having a lumen terminating at an orifice at a first end of the conduit implantable in the source body space through an opening formed in a tissue wall of the source body space, and a second end of the conduit implantable in the destination element through an opening in a surface of the destination element; and a circumferential flange, radially extending from the conduit proximate the conduit first end, configured to be implanted in the source body space adjacent an opening in the tissue wall of the source body space such that the conduit extends through the opening, the flange comprising one or more circumferentially adjacent sections at least one of which has a rigidity that decreases in a radially-increasing direction.

1. An implantable flow connector implantable into a body of a patient for fluidly coupling a first space within the body with a second space within the body, the implantable flow connector comprising: a conduit having a lumen having a first orifice at a first portion of the conduit and a second orifice at a second portion of the conduit, the conduit configured to be implanted into the second space within the body to provide communication between the first and second spaces within the body; anda flange radially extending from the first portion of the conduit and having an upper surface and a lower surface, the upper surface facing the conduit, the flange configured to be implanted in the first space within the body, the flange having first and second longitudinal sections extending on first and second opposing sides of the conduit and first and second lateral sections extending on third and fourth opposing sides of the conduit, the flange further having an inner section and a contiguous outer section, the inner section being closer to the conduit from which the flange extends than the outer section is to the conduit from which the flange extends, wherein the outer section of the flange is more flexible than the inner section of the flange, and the longitudinal sections pre-formed at an upward angle from the inner section to the outer section. 2. The implantable flow connector of claim 1, wherein the inner section of the flange includes a reinforcement region located on the upper surface the flange to increase rigidity of the inner section. 3. The implantable flow connector of claim 2, wherein the flange includes a sealing region spaced laterally outwardly of the reinforcement region and the reinforcement region has a rigidity greater than a rigidity of the sealing region. 4. The implantable flow connector of claim 2, wherein the reinforcement region is composed of a material more rigid than other regions of the flange. 5. The implantable flow connector of claim 2, wherein the reinforcement region is substantially contiguous and extends circumferentially around the conduit. 6. The implantable flow connector of claim 2, wherein the reinforcement region includes multiple reinforcement regions disposed circumferentially around the conduit. 7. The implantable flow connector of claim 1, wherein the first space within the body is a source body space and the flange is inserted through an opening formed in a wall of the source body space, and the second space within the body is a destination element and the conduit is insertable into the destination element through an opening in the destination element. 8. The implantable flow connector of claim 1, wherein the conduit and the flange are each manufactured separately of one another and subsequently joined together. 9. The implantable flow connector of claim 1, wherein the conduit has an outer surface, and the second space within the body is pressed against the outer surface by an external retaining element. 10. The implantable flow connector of claim 1, wherein the first and second lateral sections of the flange are configured to cooperate with walls of the first space such that the flange sealingly conforms to an inner surface of a tissue wall adjacent an opening in the first space. 11. The implantable flow connector of claim 1, wherein the first longitudinal section forms a toe of the flange having a rounded apex and the second longitudinal section forms a heel of the flange having a pointed apex. 12. The implantable flow connector of claim 1, wherein the first and second longitudinal sections extend further radially from the conduit than the first and second lateral sections. 13. An implantable flow connector implantable into the body of a patient for fluidly coupling a first space with the body with a second space within the body, the implantable flow connector comprising: a conduit having a lumen, a first orifice at a first portion of the conduit and a second orifice at a second portion of the conduit, the conduit configured to be implanted into the second body space to provide communication between the first and second spaces within the body; anda flange radially extending from the first portion of the conduit, the flange having an upper surface and a lower surface, the upper surface facing the conduit, the flange configured to be implanted in the first space within the body, the flange having an outer section, an inner section, first and second longitudinal sections extending on first and second opposing sides of the conduit and first and second lateral sections extending on third and fourth opposing sides of the conduit, the inner section being closer to the conduit from which the flange extends than the outer section is from the conduit from which the flange extends, wherein the inner section of the flange includes a reinforcement region to render the inner section of the flange less deflectable, and the longitudinal sections pre-formed at an upward angle from the inner section to the outer section. 14. The implantable flow connector of claim 13, wherein the reinforcement region extends in a portion of the lateral sections and a portion of the longitudinal sections. 15. The implantable flow connector of claim 14, wherein the reinforcement region is on the upper surface. 16. The implantable flow connector of claim 14, wherein the reinforcement region extends circumferentially around the conduit. 17. The implantable flow connector of claim 14, wherein the reinforcement region forms a region of increased wall thickness of the flange.
