After establishing a contract, the prescribed Bigfoot supplies are delivered in a "one-stop-shop" directly to the patient's door each month. Information about the Bigfoot Unity program can be found on the Bigfoot Biomedical website.

Patient Considerations
Active Lifestyle
Light on body. Pens are easy to use and do not remain attached to the body, senor is light on the body.
Body free of devices. Does not remain attached to the body.
Avoiding Highs and Lows
Limited customizability. System integrates the FreeStyle Libre 2 CGM for high/low alerts but requires manual dose adjustment and limits the ability to adjust basal insulin throughout the day.
Very short-acting. Absorbs quickly through the lungs to correct high blood sugar but requires attention to prevent lows.
Comfort
Many components. Have to carry pens, smart caps, pen needles, and CGM is attached to the body.
Many components. Have to carry multiple cartridges that can be bulky.
Easy Insulin Dosing
Dosing recommendations. Displays dosing recommendations and reminders for long-acting insulin.
Less precise but easy dosing. Dosing may be less precise due to the inhaled method of dosing, but color-coded cartridges make dosing easier. Dosing can also be done based on small, medium, or large meals and can be administered 1-2 hours post meals.
Easy to Use
Simple design. One-button device with easy to read display.
Simple design. Whistle-like device for inhaling insulin.
Fewer Fingersticks
Factory-calibrated sensor. Finger sticks needed for backup only.
Frequent finger-sticks are required.
Privacy
Hideable. Pens are portable but visible when in use. Frequent injections are unavoidable. Sensor is the smallest option available.
Hideable. Small, discreet, and portable device that's not as noticeable as injections.
