Abstract:
1. A one-part reconstitution device for temporarily separating two substances into two compartments within a cartridge or syringe and allowing for mixture of the two substances within the cartridge or syringe, the device comprising: an outer, contact portion configured to contact an inner surface of the cartridge or syringe; and an inner, deflection portion positioned within the contact portion, wherein the deflection portion is movable from a locked position, in which the deflection portion causes the contact portion to exert a first radial force against the inner surface, to an unlocked position, in which the deflection portion causes the contact portion to exert a second radial force against the inner surface, wherein the second radial force is less than the first radial force, and wherein movement of the deflection portion from a locked to an unlocked position allows the two substances in the two compartments to mix without piercing the deflection portion, and wherein the contact portion and the deflection portion comprise one part.
