Claim 0:
1. A drug delivery device comprising:
a housing having a proximal end and a distal end;
an activation mechanism disposed at the proximal end of the housing;
a drive mechanism disposed in the housing the drive mechanism including a biasing member;
a drug container disposed in the housing, the drug container defining a longitudinal drug container axis;
a fluid pathway connection disposed in the housing, the fluid pathway connection including a piercing member defining a longitudinal piercing member axis;
a needle insertion mechanism disposed in the distal end of the housing, the needle insertion mechanism including an insertion needle defining a longitudinal insertion needle axis and further including an insertion biasing member retained in a compressed state at the distal end of the housing,
wherein the longitudinal drug container axis, the longitudinal piercing member axis, and the longitudinal insertion needle axis are substantially coaxial; and
a plunger seal disposed in the drug container, wherein the biasing member of the drive mechanism is configured to apply a force on the plunger seal in response to actuation of the activation mechanism, the force directed toward a distal end of the drug container, and
wherein upon actuating the activation mechanism, the insertion biasing member decompresses, thereby driving and causing the insertion needle to extend in a distal direction toward the distal end of the housing.
