PRE-FILLED FLUID CARTRIDGE AND FILLING METHODS

摘要

Disclosed are cartridge filling systems and methods that can include providing a vial body defining a vial lumen, providing a floating stopper positioned within the vial lumen, providing an end cap, where the proximal end of the end cap can abut the distal end of the floating stopper such that the floating stopper is prevented from moving distally within the vial lumen, filling at least a portion of the vial lumen with a fluid, and removing the end cap from the vial body after filling at least a portion of the vial lumen with a fluid.
