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.

Abstract: A shoulder arthrometer for measuring glenohumeral joint translation upon application of a force to an arm of a patient. It includes an arm attachment assembly, a force measurement gauge, a translation measurement gauge assembly, and a girdle assembly. The arm attachment assembly is capable of being secured to the arm of a patient. The force measurement gauge is operably engaged with the arm attachment assembly for measuring a force applied to the arm attachment assembly in anterior-posterior directions and the inferior direction. The translation measurement gauge assembly is operably engaged with the arm attachment assembly. It is capable of measuring anterior-posterior translations and inferior translations relative to the arm of a patient and includes a girdle connecting element. The girdle assembly is operably engageable with the girdle connecting element. The girdle assembly is capable of being secured to the torso of the patient to provide a fixed point of reference.
