Abstract
A pressure generator for intravascular dilators includes a ram and a syringe holder. A screw drive having a large mechanical advantage is coupled for advancing the ram at a controlled rate. A coupler at one end of the ram is adapted to engage one end of a syringe plunger whereby dilation liquid will be discharged at a controlled pressure from the syringe as the ram is advanced. The pressure generator may be provided with a pistol grip and the ram may be calibrated for direct pressure readout.
