Abstract
A surgical access device adapted for disposition relative to an incision in a patient comprising a valve including a plurality of overlapping sheets defining an access channel, and a ring having an inner diameter for holding the valve by fixing each of the overlapping sheets along a portion of the perimeter is described. The access channel extends into communication with the incision in the patient. Each of the overlapping sheets includes a portion of the perimeter that is not fixed to the inner diameter of the ring, which provide open edges defining the access channel. The open edges slightly overlap at the center of the ring.
