AbstractAn adapter seal for use with a cannula assembly is provided. The adapter seal gives a surgeon increased flexibility in performing endoscopic procedures by allowing the use of variously sized instruments through a single cannula. The adapter seal is preferably provided with a stabilizer plate to limit the eccentric movement of an instrument relative to the seal, which may inadvertently release the gaseous seal.
