ABSTRACT:
A valve assembly adapted for introduction of an elongated object into a patient's body having a first valve formed of a resilient material and defining an aperture for reception of the object, the aperture being configured and dimensioned such that insertion of the object into the aperture will cause the resilient material defining the aperture to resiliently engage the outer surface of the object in a fluid tight manner. A second valve is positioned adjacent and distal of the first valve in general alignment therewith, whereby the second valve defines an aperture in general alignment with the aperture of the first valve, and is formed of a flexible material at least in the region defining the apeture. A pair of manually operable clamps are provided to selectively permit the aperture of the second valve to be opened or closed so as to permit entry of the object such that the object first passes through the first valve and then the second valve prior to entry into the patient's body.
