#$%^&*AU2008202234B220130919.pdf#####ACCESS ASSEMBLY WITH WHISKER SEAL Abstract A valve assembly for the sealed reception of a surgical instrument inserted 5 through a cannula assembly (100) includes a valve body defining a central longitudinal axis, and an elongated seal member (306) having a resilient sealing structure defining an aperture (330) in general alignment with the central longitudinal axis. The sealing structure includes a plurality of elongated bristle members (328) positioned to engage the outer surface of the surgical instrument in a fluid-tight manner upon at least partial io insertion of the instrument into the valve body. Each bristle member (328) is adapted to be displaced relative to the longitudinal axis to facilitate expansion of the aperture (330) to accommodate variously sized surgical instruments. Bristle members (328) are arranged in a pattern facilitating the reduction of the insertion force required to introduce an instrument while providing robust lateral support for the instrument. 1241914-1MLW1/10 1Co C-4 C13~ ccJ2/10 c-.m. cocm~ /l Cl3/10 Co CW), C.,> Coo C,1J C.,> coo cC., cr>, co, CC., C >D cclJ
