Multiple port fluid control valves

A fluid control valve for controlling fluid flow between a catheter, a saline supply, a waste dump, a contrast supply and an injector, the control valve comprising:

• a single valve means movable to at least three rotational positions including
• a contrast position where the valve means provides communication between the injector and the contrast supply while isolating the saline supply,
• a saline/waste position where the valve means provides communication between the injector and the saline supply and the waste dump while isolating the contrast supply, and
• an injection position where the valve means provides communication between the injector and the catheter while isolating the contrast supply.

A fluid control valve for controlling fluid flow between a catheter, a saline supply, a waste dump, a contrast supply, a pressure transducer and an injector, the control valve comprising:

• a single valve means movable to at least three rotational positions including
• a contrast position where the valve means provides communication between the injector the contrast supply while isolating the saline supply and while isolating the catheter and pressure transducer from the injector but providing communication between the catheter and the pressure transducer,
• a saline/waste position where the valve means provides communication between the injector and the saline supply and the waste dump while isolating the contrast supply and while isolating the catheter and pressure transducer from the injector but providing communication between the catheter and the pressure transducer;
• and
• an injection position where the valve means provides communication between the injector and the catheter while isolating the pressure transducer, contrast supply and waste dump.
