A pressure activated valve for a three-way connection between a catheter, an
injector
and a pressure transducer is disclosed. The valve includes a body that has an inlet
for connection to an injector, an outlet for connection to a catheter and a secondary
connection for connection to a pressure transducer. The body also includes a seal
seat disposed between the secondary connection in both the inlet and the outlet.
The body is flexibly connected to a plug seal. The plug seal is disposed between
the seal seat in both the inlet and the outlet. The plug seal is movable between
an open position spaced apart from the seal seat and biased towards the inlet and
the outlet and a closed position against the seal seat thereby isolating the secondary
connection from both the inlet and the outlet.
