ABSTRACT:
A fluid delivery apparatus including a chamber for holding a conduit, such as a portion of a human vascular tissue, a fluid supply source for delivering a fluid into the conduit and a fluid pressure modulating device for modulating the fluid pressure supplied from the fluid source before the fluid enters the conduit. The modulating device produces a fluid having a desired pressure waveform for delivery to the conduit. The modulating device includes a microprocessor that digitizes the desired pressure waveform into a plurality of discrete digitized data points and stores a motion controller computer program. The modulating device further includes a motion controller which receives the digitized data points and the motion controller computer program and which at least partially restricts the delivery of the fluid to the conduit based on the digitized data points and the motion controller computer program to produce the desired pressure waveform for delivery to the conduit. An associated method of delivering a fluid having desired pressure to a conduit is also provided.
