Improved fluid delivery apparatus for use in a variety of medical catheterization procedures, such as angiography are disclosed. In one aspect, the apparatus includes a manifold having a lumen and a first port connected to the lumen. The first port has a first branch for connecting to a first fluid reservoir and a second branch for connecting to a second fluid reservoir which is usually radiopaque material (dye fluid). The apparatus also includes a shutter assembly that facilitates control of fluid flow from the first fluid reservoir, from the second fluid reservoir, and through the lumen. In another aspect, the fluid delivery apparatus includes a manifold having a lumen with a first end for connecting to a catheter and a second end for connecting to a syringe. The manifold also has a first port proximate the catheter with a first end connected to the lumen and a second end for connecting to a pressure measuring means. The apparatus also includes a shutter assembly that facilitates generally constant, automatic measurements of a patient's blood pressure, without the need to repeatedly move external controls.
