1. A nested syringe assembly, comprising:
a first syringe having a proximal end, a distal tip, and a cylindrical body defining an inner diameter;
a second syringe having a proximal end, a distal tip and a cylindrical body defining ar outer diameter,
wherein the outer diameter of the second syringe is less than the inner diameter of the first syringe, and
wherein at least a portion of the proximal end of the second syringe is disposed within the proximal end of the cylindrical body of the first syringe such that the distal tip of the first syringe is pointed in an opposite direction from the distal tip of the second syringe;
a first plunger seal assembly positioned within the cylindrical body of the first syringe; and
a second plunger seal assembly positioned within the cylindrical body of the second syringe,
wherein at least one of the first plunger seal assembly and the second plunger seal assembly is located at a distal end of an interior space of the cylindrical body of the first syringe or an interior space of the cylindrical body of the second syringe, respectively,
wherein an interior volume is formed in the nested syringe assembly by the overlap of the cylindrical body of the first syringe or the cylindrical body of the second syringe.
