Abstract
A system for storing and delivering a predetermined amount of fluid includes a syringe including a barrel, a flange disposed at the proximal end of the barrel, and a plunger assembly configured to be received in the lumen of the barrel. The plunger assembly includes a piston and a plunger rod. The plunger rod is removably couplable to the piston at the distal end of the plunger rod and includes a thumb press flange at the proximal end of the plunger rod. The system further includes a stop feature that is removably couplable to the syringe or the plunger assembly. The stop feature is configured to arrest distal advancement of the plunger assembly relative to the syringe when the plunger assembly reaches a predetermined position relative to the syringe. The stop thus ensures that a predetermined amount of fluid remains in the barrel.
