Abstract: A fluid delivery device has a syringe barrel with reservoir chamber for fluid, a plunger that translates along a longitudinal axis to expel fluid, and a pusher dimensioned to translate within the barrel and coupled to a drive mechanism to controllably contact and move the plunger. The pusher contacts the plunger at its mechanical center to reduce tilt in the plunger. Contact faces of the pusher and plunger cooperate as a ball joint to minimize non-axial forces on the plunger face. The pusher can have a protrusion of various lengths extending toward and being at least partially received in a recess of various depths in the plunger. The pusher is rigidly connected to a drive mechanism for anti-rotation. The pusher can have scalloped edges for air venting, and apertures for cooperating with protrusions on the drive mechanism to prevent bottoming out the plunger when filling.

Abstract: A fluid delivery device (110) comprising an integrated vial connector system (180) disposed in a fluid path (124) between a reservoir (122) and an insertion mechanism (116). Additionally, a fluid delivery device (210) and an external fill device (294) wherein when the external fill device (294) engages the fluid delivery device (210), a main drive gear (234) is disengaged and a leadscrew (236) is engaged for filling the fluid delivery device (210) with the medicament. Also, a vial adapter (280) comprising an elastomer (282) that engages an outer diameter of a cannula (217) in an insertion mechanism (216) to provide a sealing surface, wherein the vial adapter (280) engages the fluid delivery device (210) and the vial (202) to fill the fluid delivery device (210) with medicament while maintaining a sealed interface. In addition, a vial adapter (380) for engaging a filling station (284) to fill a fluid delivery device (210).
