ABSTRACT:
A fluid flow regulating and control unit for intravascular catheter systems used in medical and surgical procedures with a slidably mounted closure member for the control fluid to the in-dwelling catheter. Force is exerted axially on an annular resilient member causing it to deform and bypass a relatively large flow of fluid through a fluid flow passage about the outer surface of a restrictor member therein; permitting the flow to pass with a predetermined minimum flow of fluid.
