1. A fluid control apparatus for controlling fluid flow between a catheter, an injector, a saline supply, a waste dump, and a contrast supply, the apparatus comprising:
- a body comprising a cavity, an outer surface and a plurality of ports providing communication between the cavity and the outer surface, the plurality of ports comprising at least one outlet port connected to the catheter, a contrast port connected to the contrast supply, at least one saline/waste port connected to the saline supply and the waste dump, the body being connected to the injector to provide communication between the injector and the cavity, the cavity accommodating a valve stem, the valve stem comprising a plurality of connecting passages extending through the valve stem including a contrast passage, a saline/waste passage and an injection passage that selectively provide communication between the cavity and the contrast port, the saline/waste port and the outlet port respectively depending upon a position of the valve stem, the valve stem being movable within the cavity to at least three positions including a contrast position where the contrast passage of the valve stem provides communication between the cavity and the contrast port, a saline/waste position where the saline/waste passage provides communication between the cavity and the saline/waste port and an injection position where the injection passage provides communication between the cavity and the outlet port.

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.
