Publication number: 20090137879Abstract: 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.Type: ApplicationFiled: January 27, 2009Publication date: May 28, 2009Applicant: APPLIED MEDICAL RESOURCES CORPORATIONInventors: Richard C. Ewers, John R. Brustad, Edward D. Pingleton, Nabil Hilal, Gary R. Dulak, Payam Adlparvar, Robert R. Bowes

Publication number: 20080200767Abstract: 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.Type: ApplicationFiled: April 23, 2008Publication date: August 21, 2008Applicant: APPLIED MEDICAL RESOURCES CORPORATIONInventors: Richard C.
