Multi-chamber syringe

A multi-chamber syringe comprising:

• a housing including an internal cavity;
• a first plunger disposed at least partially within the internal cavity of the housing, wherein the first plunger is slidably displaceable relative to the housing;
• a second plunger disposed at least partially within the internal cavity of the housing, wherein the second plunger is slidably displaceable relative to the housing;
• and
• a barrier disposed at least partially between the first plunger and the second plunger within the internal cavity of the housing such that the barrier is co-axial with the first and second plungers and the second plunger is positioned radially outward relative to the barrier about a longitudinal axis of the syringe, wherein the barrier forms a first chamber bounded by at least a first surface of the barrier and a distal surface of the first plunger and a second chamber bounded by at least a second surface of the barrier and the distal surface of the second plunger, and wherein the barrier is slidably displaceable relative to the first plunger and the second plunger to facilitate mixing between volumes of the first and second chambers.
