Abstract
A self-sealing closure device adapted to selectively seal an extra-ocular end of a cannula. The closure is designed to prevent the flow of fluids through the cannula in the absence of an instrument being positioned within the cannula. The elastic closure includes a first portion that extends at least partially around an outside surface of the extra-ocular end of the cannula and a second portion that extends at least partially within the extra-ocular end of the cannula. A passageway extends through the second portion of the closure and is selectively sealed by a septum having multiple elastic flaps. The flaps are selectively moveable to control the movement of fluids through the elastic closure.
