Abstract
A surgical access device for providing gas tight communication to an anatomical cavity which facilitates the insertion and use of surgical instruments while maintaining the anatomical cavity. The access device allows for the use of laparoscopic instruments in tight surgical locations without the need for a trocar or other supportive device. In addition, the surgical access device allows the use of non-laparoscopic instruments in a laparoscopic setting to add flexibility and improved sterility to an open surgery. Increased surgical instrument access and mobility within the anatomical cavity is achieved with a reduced need for insufflation. The access surgical device includes a flexible planer base with an integral opening for isolating and maintaining an open surgical incision. A hollow stem having an instrument seal is attached to the base over the incision. The stem also includes a valve for maintaining a positive gas pressure within the anatomical cavity.
