PROBLEM TO BE SOLVED: To provide an access port with relative ease and an associated introducer. SOLUTION: A surgical portal and introducer assembly includes the introducer generally secured to a tissue tract in substantial sealed relationship with the tissue tract, the introducer having a surface member and a portal member extending from the surface member, the surface member being dimensioned to limit the positioning of the portal member within a tissue tract, the portal member and the surface member defining a longitudinal channel therethrough; and a portal positionable within the longitudinal channel of the introducer, the portal having at least one longitudinal port dimensioned to permit passage of a surgical object therethrough, the portal includes a compressible material that permits the portal to transition between a first expanded condition and a second compressed condition to facilitate passage through the longitudinal channel of the introducer, the portal being biased toward the first expanded condition, wherein the portal maintains a substantially sealed relationship with the longitudinal channel of the introducer when positioned in the longitudinal channel and disposed in the expanded condition.
