1. A wearable infusion pump assembly comprising:
a reservoir;
a controller; and
a fluid delivery system having a fluid path to deliver an infusible fluid from the reservoir to a fluid delivery system outlet, the fluid delivery system comprising:
a pump assembly for extracting a quantity of the infusible fluid from the reservoir and providing the quantity of the infusible fluid to the fluid delivery system outlet, the pump assembly having a displaceable member which is displaced as the infusible fluid is transferred with actuations of the pump assembly;
a first sensor assembly including a light emitter and a sensor, and configured to optically sense movement of the displaceable member which is displaced as the infusible fluid is transferred with actuations of the pump assembly;
a first valve assembly selectively isolating the pump assembly from the reservoir;
a second valve assembly selectively isolating the pump assembly from the fluid delivery system outlet;
a second sensor assembly, including a light emitter and a sensor, to optically sense the movement of the second valve assembly;
a disposable housing assembly including the reservoir and a first portion of the fluid delivery system; and
a reusable housing assembly including a second portion of the fluid delivery system.
