Abstract
A drive system for a drug delivery system includes a pressure chamber, a primary container, and a pressurized fluid. The pressure chamber has an outer surface and an inner surface that defines an interior volume. The primary container also has an outer surface and an inner surface that defines an interior volume to store a medicament to be administered to a user. The primary container is at least partially disposed within the interior volume of the pressure chamber. The pressurized fluid is disposed in the interior volume of the pressure chamber and is pressurized to exert a pressure on at least a portion of the outer surface of the primary container.
