Abstract
A low profile surgical access device includes an elongated cannula having an opening defined at a proximal end thereof including an inner peripheral surface dimensioned to facilitate passage of instrumentation therethrough and an outer peripheral surface configured to operatively engage and removably secure to tissue via, e.g., fixation ribs, adhesive, anchors, clips, suction elements, expandable materials and/or combinations thereof. A valve is operatively coupled to the elongated cannula and provides a substantially fluid tight seal when instrumentation is inserted through the cannula. A seal housing is included which is positionable relative to the cannula and which is configured to operatively engage and removably secure to tissue. The instrument seal in the seal housing is positioned in vertical registry with the valve in the elongated cannula.
