Abstract:
A barrel is provided having open proximal end and a closed distal end, and at least one groove in an interior wall thereof. The groove(s) define a length extending a distance from the open end of the barrel toward the distal end of the barrel and defining a substantially constant depth and width along the length thereof. A piston is in sealing engagement with the interior wall of the barrel. The groove(s) permits fluid to bypass the piston when positioned along the groove(s). At least a portion of the piston is positioned distally from the groove(s), thereby sealing substance within the barrel.

Claim (Index 3):
The method of  claim 1 , wherein the piston includes at least one annular rib projecting radially therefrom for slidable sealing engagement with the interior wall of the medical administration barrel; and wherein the ceasing step comprises ceasing physical advancement of the piston upon positioning of the at least one rib at the initial portion of the interior wall of the medical administration barrel free of the at least one groove, such that the at least one annular rib sealingly engages the interior wall of the medical administration barrel, thereby providing the air-tight seal inside the portion of the medical administration barrel between the piston and the distal end of the medical administration barrel.
