Abstract
An apparatus includes a housing, a medicament container disposed within the housing, a first energy storage member and second energy storage member. The medicament container includes a first plunger disposed within a proximal end portion of the medicament container and a second plunger disposed within the medicament container spaced apart from the first plunger. The first energy storage member is configured to produce a force when actuated to move at least the second plunger within the medicament container. The second energy storage member is configured to produce a force when actuated to move the first plunger and the second plunger within the medicament container. The second energy storage member is different than the first energy storage member.
