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.

1. A stopper configured to slidably move within a hollow lumen of a syringe to facilitate movement of fluid within the syringe, the stopper comprising: a base; andone or more capture members extending rearwardly from the base, the one or more capture members each comprising a beveled edge,wherein the beveled edge is configured to interact with a piston of a fluid injection apparatus and 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, andwherein the stopper is configured for slidable movement within a body of a syringe and to form a fluid tight seal with an inner wall of the body of the syringe. 2. The stopper according to claim 1, wherein each of the one or more capture members comprise an inwardly facing shoulder. 3. The stopper according to claim 2, wherein the one or more capture members extend rearwardly from the base by an amount sufficient to releasably capture and retain a tapered flange on a coupler attached to the piston. 4. The stopper according to claim 3, wherein upon rotation of the stopper relative to the piston, the beveled edge is configured to be pushed radially outward such that the inwardly facing shoulders of the one or more capture members are disengaged from the tapered flange. 5. The stopper according to claim 3, wherein the inwardly facing shoulder of each of the one or more capture members is configured to engage a circumferential groove proximal to the tapered flange on the piston. 6. The stopper according to claim 5, wherein the one or more capture members may further comprise one or more extensions which extend proximally from the inwardly facing shoulder. 7. The stopper according to claim 5, wherein the one or more capture members are formed from a flexible material such that the one or more capture members flex radially outward when contacted by a taper of the tapered flange and subsequently snap back to an original position after passing the tapered flange to engage the circumferential groove. 8. The stopper according to claim 5, wherein the stopper is configured to resist disconnection from the piston upon rearward movement of the piston. 9. The stopper according to claim 5, wherein the one or more capture members are designed such that forces exerted on the one or more capture members upon a rearward movement of the piston substantially prevents radially outward movement of the one or more capture members. 10. The stopper according to claim 9, wherein a bending movement created by the rearward movement of the piston causes the one or more capture members to deflect radially inward. 11. The stopper according to claim 1, wherein the base is detachable from the stopper. 12. The stopper according to claim 1, wherein the stopper comprises a cylindrical body and is configured to substantially fill at least a portion of a conical shaped distal end of the syringe. 13. A plunger apparatus comprising: a stopper configured to slidably move within a hollow lumen of a syringe to facilitate movement of fluid within the syringe, the stopper comprising: a base; andone or more capture members extending rearwardly from the base, the one or more capture members each comprising a beveled edge and an inwardly facing shoulder,wherein the beveled edge is configured to interact with a piston of a fluid injection apparatus and 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. 14. The plunger apparatus of claim 13, further comprising a coupler for connection to a distal portion of the piston, wherein the coupler comprises a substantially circumferential groove having a plurality of extensions extending radially from the circumferential groove, wherein the extensions are configured to facilitate removable attachment of the stopper to the piston and wherein the inwardly facing shoulder of the one or more capture members are configured for engaging the circumferential groove. 15. The plunger apparatus of claim 14, wherein the coupler is fixedly attached to the distal portion of the piston. 16. The plunger apparatus of claim 14, wherein each of the plurality of extensions includes one or more notches on one or more sides of each extension on an outermost portion of each extension, wherein each of the one or more notches has a cross-sectional shape that is square, rectangular, triangular, circular, or elliptical. 17. The plunger apparatus of claim 14, wherein the coupler comprises a tapered flange extending distally from the circumferential groove, wherein the tapered flange is configured to removably secure the coupler to the stopper by locking with one or more capture members located on the stopper. 18. The plunger apparatus of claim 17, wherein the one or more capture members is constructed of a flexible material such that the one or more capture members flex outwardly when contacted by the tapered flange and subsequently snap back to an original position after passing the tapered flange to engage the circumferential groove. 19. The plunger apparatus of claim 17, wherein the one or more capture members protrude rearwardly beyond a rear surface of the base by an amount sufficient to capture and retain the tapered flange to effectively resist disconnection of the stopper from the piston. 20. The plunger apparatus of claim 19, wherein the one or more capture members may be configured to move radially outward from the base as a radial distance of the circumferential groove increases when the piston is rotated about an axis, allowing the piston to be detached from the stopper.
