introducing a closure device through the tissue tract;
deploying an expansible member at a distal end of the closure device within the blood vessel
retracting the closure device through the tissue tract so that the deployed expansible member is seated against the puncture site;
deploying a tensioning coil proximal the deployed expansible member to seal the deployed expansible member against the puncture site;
gauging, with the aid of the tensioning coil, tension applied to the deployed expansible member as the expansible member is seated against the puncture site; and
exposing a chemical and/or biological agent release region proximal the expansible member within the tissue tract as the tensioning coil is deployed.
