Abstract
A seal is adapted for use with a suction and/or irrigation device to prevent fluid flow through a flow passage defined in the device when an instrument is inserted therethrough. The seal includes a wall traversing the flow passage. A peripheral portion of the wall occupies a plane substantially perpendicular to of the flow passage and a central portion of the wall extends away from that plane in a direction toward the device's opening. The central portion of the wall is pierceable by an instrument and the central portion is adapted for sealing contact with an external surface of the instrument upon such insertion. A seal assembly and a suction-irrigation device are also described.
