26. An insulin delivery system comprising:
a reservoir configured to hold an insulin medication therein;
an infusion hub;
tubing connecting the insulin reservoir and the infusion hub;
a cannula configured to deliver the insulin medication to a patient; and
a filter configured to capture particulates from the insulin medication prior to delivery of the insulin to the patient,
wherein the filter comprises features internal to the cannula and in fluidic contact with the insulin configured to affect hydrodynamic flow characteristics of insulin medication flowing within the cannula and to create pressure differential regimes to promote the capture and retention of aggregate particles that have formed out of solution.
