1. An intrabody fluid transfer system comprising:
a cannula assembly comprising a proximal end with a luer connector and having a longitudinally opposing distal end with an open channel extending therethrough; and
a plunger assembly coupled to the cannula assembly, the plunger assembly comprising a stylet that extends in the open channel of the cannula assembly to position a distal end of the stylet adjacent the distal end of the cannula assembly, wherein the open channel and the stylet cooperate to define a fluid channel, and wherein the stylet provides or is attached to a drive member of the plunger assembly to controllably retract and extend the stylet relative to the cannula assembly whereby longitudinal retraction of the stylet in the open channel of the cannula assembly creates a vacuum sufficient to front-load fluid into the open channel at the distal end of the cannula assembly.
