ABSTRACT:
Disclosed is a lavage valve apparatus and a method of using the valve. The valve comprises a valve body having three apertures and a bypass passageway. A movable valve member with truncated end portions moves linearly within the valve body by means of hydraulic pressure or mechanical (or magnetic) bias. Application of hydraulic pressure via a syringe pumps irrigation fluid through the valve into the patient. Termination of hydraulic pressure allows mechanical re-seating of the movable valve member and vacuum withdrawal of the fluid.
