Abstract
An actuator for an infusion drive mechanism comprises a piston defining a first axis and being movable within a passageway of the infusion drive mechanism to convey at least one infusion medium. The passageway defines a longitudinal axis. An armature is connected to the piston and defines at least one cavity configured for disposal of a biasing member engageable with a surface of the infusion drive mechanism to orient the first axis transverse relative to the longitudinal axis. Systems and methods of use are disclosed.

An actuator for an infusion drive mechanism, the actuator comprising:
- a piston defining a first axis and being movable within a passageway of the infusion drive mechanism to convey at least one infusion medium, the passageway defining a longitudinal axis;
- a pole being connected to the piston and defining at least one cavity disposed adjacent to and non-concentric with the piston;
- and a biasing member located within the at least one cavity and engaged with a surface of the infusion drive mechanism to orient the first axis transverse relative to the longitudinal axis.
