ABSTRACT:
An assembly structured to introduce a trocar or other medical instrumentation into a body cavity through an entry site formed in the cavity wall. The introducer assembly includes a base formed of a semi-rigid, flexible and/or a semi-flexible material having an instrument receiving passage extending there through, and further including an exterior sealing surface extending between proximal and distal portions of the base. The sealing 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 thereby established between the exterior of the base and the peripheral tissue surrounding the entry site, particularly when the entry site is formed by an incision commonly utilized an open laparoscopic procedure.
