An adapter for use with a coaxial activating syringe balloon catheter assembly is provided with a simplified slide valve which permits a precise amount of fluid to be introduced into the balloon and held therein. The fluid is injected by means of a metering syringe which can thereafter be removed without deflating the balloon. A simple longitudinal movement of the adapter will release the fluid pressure in the balloon for deflation when desired.
