Abstract
A cannula anchoring system for anchoring a cannula in a cavity wall includes a cannula adapted to be inserted through the cavity wall and having a lumen for communication with the cavity and one or more tissue penetrating members carried by the cannula and movable between non-exposed, retracted positions and exposed extending positions where the tissue penetrating members penetrate the cavity wall adjacent the cannula to anchor the cannula therein. The anchoring system can be used for stabilizing the cannula longitudinally and in desired angular orientations, manipulating for lifting the cavity wall and/or in combination with lengths of suture material passed through or attached to the tissue penetrating members for puncture site closure.
