Abstract
A stopper configured to slidably move within the hollow lumen of a syringe to facilitate movement of fluid within the syringe. The stopper includes a base and one or more capture members extending rearwardly from the base. The one or more capture members each include a beveled edge configured to interact with a piston of a fluid injection apparatus, wherein the one or more capture members are radially deflected upon rotation of the stopper relative to the piston to facilitate removal of the stopper from the piston. The stopper is configured for slidable movement within a body of a syringe and forms a fluid tight seal with an inner wall of the body of the syringe. Also disclosed is a plunger which includes the stopper.
