Conduit device and system for implanting a conduit device in a tissue wall

A method for establishing fluid communication between a first surface and a second surface of a tissue wall, the method comprising:

• engaging the tissue wall with a conduit device such that a substantially fluid-tight seal is established between the conduit device and the tissue wall, the conduit device comprising an outer tube;
• after engaging the tissue wall with the conduit device, advancing a coring device through the outer tube of the conduit device and through the tissue wall to core an aperture in the tissue wall extending from the first surface to the second surface of the tissue wall while maintaining the substantially fluid-tight seal between the conduit device and the tissue wall, the coring device comprising a coring tube;
• and
• inserting an inner tube through the outer tube of the conduit device and through the aperture in the tissue wall.

A system for establishing fluid communication between a first surface and a second surface of a tissue wall, the system comprising:

• a conduit device configured for engaging the tissue wall such that a substantially fluid-tight seal is established between the conduit device and the tissue wall, the conduit device comprising an outer tube;
• a coring device configured for advancing through the outer tube and through the tissue wall to core an aperture in the tissue wall extending from the first surface to the second surface of the tissue wall after engaging the tissue wall with the conduit device and while maintaining the substantially fluid-tight seal between the conduit device and the tissue wall, the coring device comprising a coring tube;
• and
