1. 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.

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.
