    摘要: 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.

    摘要: 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.

    摘要: A surgical access device is adapted for performing laparoscopic surgical procedures with at least one instrument passing through the surgical access device and through an incision in the abdominal wall of a patient with the abdominal cavity pressurized with an insufflation gas. The surgical access device comprises an access seal. The material of the access seal is adapted to form a seal to generally maintain insufflation pressure within the abdominal cavity. At least one opening is formed through the material of the access seal between a proximal portion and a distal portion of the access seal. The at least one opening when operatively disposed is in communication with the incision and forms a working channel between a location external to the abdominal wall and a location internal to the abdominal wall. The material of the access seal conforms to a surface of an instrument inserted through the working channel.

    摘要: Apparatus, systems and methods for delivering brachytherapy to a target tissue region of a human or other mammalian body. In some embodiments, a flexible brachytherapy device is implanted that includes a therapy delivery portion having one or more radioactive sources securely retained thereto, and a tail portion extending from the therapy delivery portion. Once implanted, the tail portion may extend outside the body, where it may be folded and secured flat against the skin. The device may be removed at therapy completion. Other embodiments of the invention are directed to systems and methods for delivering brachytherapy devices to the body.
