1. A fluid path set for a fluid delivery system, the fluid path set comprising:
a manifold comprising at least two fluid control valves in series fluid communication, wherein a first fluid control valve comprises a first port, a second port, and a third port, wherein the second port of the first fluid control valve is in fluid connection with a first port of a second fluid control valve and wherein a second port of the second fluid control valve is in fluid connection with a catheter connector conduit;
a connector for providing fluid connection between a low pressure hand-operated syringe and the first port of the first fluid control valve;
a tubing for providing fluid connection between a high pressure syringe and the third port of the first fluid control valve; and
a pressure sensor in continuous fluid communication with fluid in a tubing portion in the catheter connector conduit and adapted to measure a fluid pressure in the tubing portion, the pressure sensor comprising a deformable element configured to deform in response to a change in the fluid pressure in the tubing portion, and
wherein the pressure sensor converts a representation of the amount of deformation of the deformable element to an electronic signal to measure the change in the fluid pressure in the tubing portion.
