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.

[ What is claimed is:] [1.] A surgical access device for isolating a superfascial incision and for providing a sealed access path for a surgical instrument into an operable region in communication with the incision, comprising:a flexible base for removable attachment to a portion of skin surrounding the incision, said base having an opening for isolating the incision and an outer peripheral edge;a generally hollow stem extending outwardly from said base, said stem having an operative passageway in communication with said opening;an instrument seal attached to said stem within said operative passageway;an operative valve attached to said stem within said operative passageway and having properties for inhibiting gas flow in response to positive gas pressures within the operable region; andwherein said instrument seal provides a gas seal around the operative instrument when the operative instrument is inserted into the stem.
