Abstract
A cannula supporting coil that comprises a thin resilient elongated member having a proximal portion; an intermediate portion; and, a distal portion. The proximal portion of the thin resilient elongated member comprises a clip portion for capturing a side port of an endoscopic or arthroscopic cannula. The distal portion has a plurality of revolutions to accommodate the main body of the cannula. A terminal portion of a final revolution of the distal portion has less curvature than previous portions of the distal portion for anchoring to an anatomical cavity lining of an anatomical cavity. The cannula supporting coil is used as a component of a cannula delivery and support system that also includes an elongated sheath for containing the cannula supporting coil during delivery of the cannula supporting coil to the anatomical cavity; and, an elongated trocar contained within the sheath. Once the cannula delivery and support system is in the cavity the trocar is reinserted in an inverted position and utilized as a plunger for the cannula supporting coil.
