Abstract:
1. A surgical access apparatus for positioning within a percutaneous tissue tract to facilitate access to an underlying surgical worksite, the surgical access apparatus comprising: a housing having proximal and distal ends and being configured to removably receive at least one surgical instrument; a tubular member extending distally from the housing along a longitudinal axis, the tubular member defining an axial lumen configured and dimensioned to allow the at least one surgical instrument to pass therethrough, the tubular member being repositionable between a first position, in which the tubular member is configured for at least partial insertion into the tissue tract, and a second position, in which the tubular member is configured to facilitate anchoring of the tubular member within the tissue tract; a connective member secured to the tubular member, the connective member being configured to contact the at least one surgical instrument upon insertion to form substantially fluid-tight seal therewith; and at least one filament secured to the connective member and extending proximally therefrom, the at least one filament being movable in a longitudinal direction relative to the tubular member to cause corresponding movement of the connective member to thereby facilitate selective repositioning of the tubular member from the first position to the second position.
