Systems for implanting and using a conduit within a tissue wall

A device for attaching to a tissue wall having a first surface and a second surface, the device comprising:

• a port defining an opening extending along a longitudinal axis of the device;
• a plurality of coils fixedly attached to the port and configured for advancing at least partially through the tissue wall such that at least a portion of each coil becomes disposed between the first surface and the second surface of the tissue wall, wherein the coils are centered on a common rotational axis;
• and
• a plug configured for releasably attaching to the port and for positioning at least partially within the opening of the port, wherein the plug comprises a valve configured for moving between a closed state and an open state to control fluid flow through the plug.
