Abstract: A catheter of the type having integrally attached fluid control means inflating a holding collar through a secondary inflation tube integrally attached longitudinally to the catheter is provided with a simple clamping means movable axially adjacent the catheter to pinch shut the fluid processing tube leading the collar and act as a fluid exit control valve. This permits the attached fluid control means such as a syringe to be severed with the inflation tube where it branches from the catheter and assures sterile delivery of a complete integral catheter array without the disadvantage of having to tape the syringe and/or an awkward clamp in place after positioning and inflating the collar.
