ABSTRACT:
A valve assembly adapted for introduction of surgical instruments into a patient's body includes a valve body formed of a flexibly resilient material which defines an aperture for reception of the instrument. The aperture is configured and dimensioned such that insertion of the instrument into the aperture will cause the resilient material of the valve body to resiliently engage the outer surface of the instrument in a substantially gas tight manner. The valve assembly includes a biasing member for closing the valve body to form a gas tight seal prior to inserting the instrument therethrough.
