The introducer assembly (10) includes a base (12) formed of a semi-rigid, flexible or semi-flexible material having an instrument receiving passage (18) extending there through, and further including an exterior sealing (40) surface extending between proximal and distal portions of the base (12). The sealing (40) surface has a predetermined configuration which is shaped to conform to the shape of the entry site as the base passes into the entry site. A fluid restricting seal is established between the exterior of the base and the peripheral tissue surrounding the enry site. A fluid restricting seal is established between the exterior of the base and the peripheral tissue surrounding the entry site, particularly when the enry site is formed by an incision commonly utilized an open laparoscopic procedure. |
