    Abstract: A surgical wound retractor is adapted to dilate a wound stretchable to a desired diameter, the retractor includes a first ring having a diameter greater than that desired for the wound and being adapted for disposition interiorly of the wound. A second ring has a diameter greater than that desired for the wound and is adapted for disposition exteriorly of the wound. A plurality of retraction elements are disposed in a generally cylindrical relationship to each other, between the first ring and the second ring. These elements extend through the wound to exert a radial retraction force on the wound which is dependent on the distance separating the first ring and the second ring. Retraction elements, both distensible and non-distensible are contemplated with appropriate attachment means at the rings to provide for variations in the retraction force. With a suitable retraction sleeve, a third ring can be provided to form a circumferential retainer to vary the retraction force. Rings can also be made inflatable or self-expanding to vary the retraction force. An associated method includes the step of rolling the second ring circumferentially of the third ring to form the circumferential retainer.

    Abstract: A surgical access device includes an access seal adapted to be disposed within an incision within an abdominal wall. The access seal has an external flange adapted to be disposed external to the abdominal wall and an internal flange adapted to be disposed internal to the abdominal wall. The access seal with flanges is formed monolithically. There are access channels through the access seal. The access channels span the thickness of the abdominal wall and form working channels between a location external to the abdominal wall and a location internal to the abdominal wall. The access seal is formed of an elastomeric material adapted to conform to a surface of an instrument inserted through the working channel to form an instrument seal along a length spanning the thickness of the abdominal wall. The elastomeric material is adapted to form an abdominal seal within the abdominal wall.

    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.
