Development of a Low-Profile Dual Hormone Patch Pump with Novel Occlusion Sensor Project Summary: The Specific Aim of this project is to develop a discrete, low-profile, dual hormone drug delivery system using SFC Fluidics? enabling microfluidic technologies. A DualPump? will be developed in which one proprietary ePump® body will independently and accurately deliver both insulin and glucagon from two separate reservoirs. Latching safety valve sets will independently and safely control the delivery of each hormone and a dispense confirmation sensor will notify the user of any dosing errors resulting from occlusions or electrical/mechanical failures. Phase II will see the integration of all components into an accurate, discrete, low-profile wearable pod, extensive benchtop testing and initial testing in swine. The end goal of Phase II is production of a DualPump module that has been introduced to the FDA and is ready to be integrated with all other components required for a dual hormone artificial pancreas. During Phase IIB, SFC Fluidics will work with manufacturers of continuous glucose monitors, control algorithms and stable drug formulations to develop an FDA-approved, robust, and reliable dual hormone artificial pancreas.
