Abstract

An endoscopic portal includes a portal sleeve for insertion through a cavity wall and a valve assembly coupled with the portal sleeve including a bladder having a valve passage therethrough for introduction of instruments of various sizes into the cavity, the bladder having walls forming the valve passage and being normally closed while permitting the valve passage to open to receive the instruments. The bladder is movable by contact with the instruments to move along with the instruments to maintain sealing contact of the bladder with the instruments.
