A surgical access assembly comprising: a sleeve assembly including a proximal ring , a distal ring , and a sleeve defining a passage therethrough, the sleeve extending between the proximal and distal rings, wherein the sleeve of the sleeve assembly is rollable about the proximal ring ; a base member including an annular body including a coupling member , the annular body defining an opening in communication with the passage of the sleeve, and a circumferential groove configured to support the proximal ring of the sleeve assembly ; and a sealing assembly including an annular frame and a seal dimensioned to cover the opening of the base member in a sealing relation, wherein the coupling member of the base member releasably secures the sealing assembly to the base member, the annular frame of the sealing assembly configured to be in registration with the annular body of the base member, such that the proximal ring is interposed between the base member and the sealing assembly, wherein the seal includes a body received in the opening of the base member and an overhang extending radially outward from the body ; characterized in that the annular body of the base member includes a plurality of lips disposed radially inward of the proximal ring of the sleeve assembly , the lips circumferentially arranged to concentrically retain the proximal ring within the circumferential groove of the annular body; the circumferential groove supports the proximal ring of the sleeve assembly such that a portion of the proximal ring extends proximally from the base member ; and the annular frame and the body of the seal define a gap therebetween, the gap dimensioned to receive at least a portion of the proximal ring of the sleeve assembly . a sleeve assembly including a proximal ring , a distal ring , and a sleeve defining a passage therethrough, the sleeve extending between the proximal and distal rings, wherein the sleeve of the sleeve assembly is rollable about the proximal ring ; a base member including an annular body including a coupling member , the annular body defining an opening in communication with the passage of the sleeve, and a circumferential groove configured to support the proximal ring of the sleeve assembly ; and a sealing assembly including an annular frame and a seal dimensioned to cover the opening of the base member in a sealing relation, wherein the coupling member of the base member releasably secures the sealing assembly to the base member, the annular frame of the sealing assembly configured to be in registration with the annular body of the base member, such that the proximal ring is interposed between the base member and the sealing assembly, wherein the seal includes a body received in the opening of the base member and an overhang extending radially outward from the body ; characterized in that the annular body of the base member includes a plurality of lips disposed radially inward of the proximal ring of the sleeve assembly , the lips circumferentially arranged to concentrically retain the proximal ring within the circumferential groove of the annular body; the circumferential groove supports the proximal ring of the sleeve assembly such that a portion of the proximal ring extends proximally from the base member ; and the annular frame and the body of the seal define a gap therebetween, the gap dimensioned to receive at least a portion of the proximal ring of the sleeve assembly . <EOS>
