Abstract
A valve assembly is provided for permitting the introduction of a surgical instrument into a patient's body while providing a substantial seal about the instrument. The valve assembly includes a sealing gasket assembly providing a fluid tight seal before instrument insertion, and is configured and dimensioned for accommodating an instrument and providing a substantial fluid tight seal after insertion of an instrument. The valve assembly may further include a deformable sealing member having a substantially central aperture for accommodating the instrument. The sealing member provides a substantial seal about the instrument when the instrument is passed therethrough impeding the egress of fluids and gasses through the valve assembly.
