Various embodiments of the present invention provide a conduit device including an attaching device configured for defining a helical pathway through a tissue wall and complementary ring in cooperation for securing the device within an aperture defined in the tissue wall. Some embodiments of the present invention further provide a system for implanting a conduit device in a tissue wall. More specifically, some embodiments provide a system including a coring device for defining an aperture in a tissue by removing and retaining a tissue core and securely implanting a conduit device therein so as to provide fluid communication between a first and second surface of the tissue wall via the conduit device.
