    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.

    Abstract: A surgical access device includes a single valve that forms a seal with the body wall and provides an access channel into a body cavity. The valve has properties for creating a zero seal in the absence of an instrument as well as an instrument seal with instruments having a full range of instrument diameter. The valve can include a gel and preferably an ultragel comprised of an elastomer and an oil providing elongation greater than 1000 percent and durometer less than 5 Shore A. The single valve can be used as a hand port where the instrument comprises the arm of a surgeon, thereby providing hand access into the cavity.A method for making the surgical access device includes the combining of a gelling agent with an oil, preferably in a molding process. A method for using the device includes steps for creating an opening with the instrument. In a particular process, an organ can be removed from the body cavity through the single valve to create an organ seal while the organ is addressed externally of the body cavity. The valve and method are particularly adapted for laparoscopic surgery wherein the abdominal cavity is insufflated with a gas thereby requiring the zero seal, the instrument seal, and the organ seal in various procedures.

    Abstract: A surgical wound retractor is adapted to dilate a wound to a desired diameter. The retractor includes first and second rings, each having a diameter greater than that desired for the wound. The first and second rings are adapted for disposition interiorly and exteriorly of the wound, respectively. A plurality of retraction elements is disposed in a generally cylindrical relationship between the first and second rings and extends through the wound to exert a radial retraction force on the wound that is dependent on the distance separating the first and second rings. Retraction elements, both distensible and non-distensible, are contemplated with appropriate attachment elements 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.

    Abstract: The invention is directed to a surgical access system that provides access to a surgical area while maintaining pneumoperitoneum during laparoscopic surgery. The access system comprises a sheath retractor adapted to dilate a wound stretchable to a desired diameter and a detachable seal adapted to be removable from the sheath retractor. In another aspect, the detachable seal comprising a valve including a plurality of overlapping sheets defining an access channel that 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.

    Abstract: A device includes an access port adapted to permit access of at least one surgical instrument into a patient. The access port includes a proximal portion, a distal portion, and an intermediate portion monolithically formed of a flexible material. At least one opening extends through the access port. The proximal portion includes a proximal flange. The distal portion includes a distal flange. The intermediate portion includes an outer surface and at least one inner surface. The access port is adapted to form a perimeter seal when the proximal flange is disposed exteriorly and the distal flange is disposed interiorly. The access port is adapted to form a seal with the at least one surgical instrument positioned through the access port. The intermediate portion conforms to the surface of the surgical instrument positioned through the at least one opening and forms the seal between the inner surface and the surgical instrument.
