Abstract: A system for controlling the flow of fluid through a medical device may include a medical device having a lumen that extends to a distal end of the medical device; a fluid source configured to supply fluid having a positive pressure to the lumen of the medical device; and a flow controller configured to apply a negative pressure to the fluid within the lumen, wherein the flow controller is triggered to apply the negative pressure upon a lowering of the positive pressure from the fluid source.
