A seat assembly (100) is provided for reception of an elongated surgical instrument (130), which comprises a body having at least one opening configured, and dimensioned to permit entry of an elongated surgical instrument (130), defining a central long axis, a seal member (118) formed of a resilient material, defining an aperture therein, the aperture being configured and dimensioned such that insertion of the surgical instrument (130) into the aperture causes the resilient material defining the aperture to resiliently contact the outer surface of the surgical instrument in a substantially fluid tight manner, the seal member (118) further including a peripheral flange element (129) which contacts a surface of the body to form a contact seal therewith, and a fabric layer juxtaposed relative to the resilient material.
