Abstract
A fluid control apparatus is disclosed for controlling fluid flow between a catheter, an injector, a saline supply, a waste dump and a contrast supply. The apparatus includes a valve stem movable within a cavity disposed in a valve body. The valve stem is movable to a plurality of positions including a contrast position where the valve stem provides communication between the injector and a contrast supply, a saline/waste position where the valve stem provides communication between the injector and a saline/waste line and an injection position where the valve stem provides communication between the injector and an outlet port connected to the catheter.
