Publication number: 20130217973Abstract: A surgical wound retractor is adapted to dilate a wound stretchable to a desired diameter through body cavities of varying thicknesses. 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 having a diameter greater than that desired for the wound and is adapted for disposition exteriorly of the wound, and a sheath disposed between the two rings. Optionally, the second ring may be detachably attached to the sheath to adapt the retractor to body cavities of varying thickness. Additional rings may be disposed along the sheath to provide for adjustment of the distance between the first and second rings. The retractor may also include an expandable foam annulus that can adjust the distance between the first and second rings.Type: ApplicationFiled: February 12, 2013Publication date: August 22, 2013Applicant: Applied Medical Resources CorporationInventors: Richard C. Ewers, John R. Brustad, Edward D. Pingleton, Nabil Hilal, Payam Adlparvar, Scott V. Taylor, Gary R. Dulak, Michael J. Dunn, Norman L. Morales, Charles C. Hart, Robert R. Bowes

Patent number: 8388526Abstract: 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: GrantFiled: April 23, 2008Date of Patent: March 5, 2013Assignee: Applied Medical Resources CorporationInventors: Richard C. Ewers, John R. Brustad, Edward D. Pingleton, Nabil Hilal, Payam Adlparvar, Scott V. Taylor, Gary R. Dulak, Michael J. Dunn, Norman L. Morales, Charles C. Hart, Robert R. Bowes

Patent number: 7238154Abstract: 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.Type: GrantFiled: September 1, 2005Date of Patent: July 3, 2007Assignee: Applied Medical Resources CorporationInventors: Richard C. Ewers, John R. Brustad, Edward D. Pingleton, Nabil Hilal, Payam Adlparvar, Scott Taylor, Gary R. Dulak, Michael J. Dunn, Norman L. Morales, Charles C. Hart, Robert R. Bowes
