Summary
The iLet Bionic Pancreas is the first and only commercially-available, automated insulin delivery system that determines 100% of insulin doses without carb counting - offering better results with less work.
The iLet only needs a user's weight to get started. It then learns and adapts to the user's insulin needs based on their meal announcements and CGM data (Dexcom CGM or FreeStyle Libre 3 Plus sensor).
The FreeStyle Libre 3 is the smallest, thinnest, all-in-one glucose sensor/transmitter CGM and lasts 14 days. This sensor sends minute-by-minute glucose readings to a compatible smartphone app and only needs fingersticks as backup. Optional low and high blood sugar notifications are available for this system.
FDA approved for insertion on the back of the upper arm (ages 4 years and older).
MARD of 7.9%.
Components

Beta Bionics iLet Pancreas : Pump
Pump connects tubing to a small patch called an infusion set that attaches to the body.

Beta Bionics iLet Pancreas : Sensor
Sensor is inserted underneath the skin, either on the abdomen or arm.

Beta Bionics iLet Pancreas : Controller
Pump receives CGM readings and automatically adjusts insulin delivery. Data from the pump and CGM viewable on compatible smartphones (iOS and Android)

Beta Bionics iLet Pancreas : Infusion Set
An infusion set contains the thin plastic tubing that delivers insulin from the pump to the body.

Freestyle Libre 3 : Sensor
Sensor uses a thin, flexible filament inserted just under the skin to measure glucose levels every minute. Push-button applicator allows sensor to be placed on the body in one step.

Freestyle Libre 3 : Receiver
Conveniently access glucose readings using a reader, smartphone, or both. Available for both iOS and Android devices.
Device Details
Overview
This system requires very little input from the physician or user. It only requires the user to input their weight to get started (glucose targets can be adjusted). Instead of carb counting,* the iLet just needs an estimate of the carbs in your meal – Usual for me, More or Less. The iLet is paired with either a Dexcom CGM or the FreeStyle Libre 3 Plus sensor.
*User must be carb aware.
Smallest, thinnest, all-in-one glucose sensor/transmitter with low and high blood glucose alarms can be worn on the upper arm.
Affordability and Access
$$$$
iLet and sensors are widely covered and provided by DME and pharmacy. Sensor price range $0-$550/month. iLet cost dependant on your insurance for DME or Pharmacy.
$$$$
Widely covered. Provided by pharmacies. Price range; $0-$100/month. Often the cheapest and easier to access sensor.
Data Monitoring Options
Yes
iLet Mobile App provides the ability to pull data from an iLet device to share with the Beta Bionics Cloud.
Yes
Sensor automatically sends data to the user’s LibreView account which enables sharing with HCPs and caregivers.
Data View Options
Yes
Users can view their iLet data directly on the pump or by using the iLet Mobile App. iLet users can share their data with friends, family, and caregivers through the Bionic Circle App.
Yes
Freestyle Libre 3 app or Libre by Abbott provides glucose readings and alarms, multiple data views, the ability to share glucose data and real-time alarms with LibreLinkUp, and the ability to connect to a clinician's practice through LibreView.
Duration and Storage
3-day pump up to 15 day sensor
Sensors last 10 or 15 days and transmitters last 90 and work at 50ºF – 108ºF. Pump can be used for up to 72 hrs, fully charged iLet will last for 4-5 days, and work between 36°F (2°C) to 86°F (30°C).
14 Days
Sensors last 14 days and work between 50ºF - 113ºF. They are shipped in orders of 1-3 months at a time - which is 2-6 boxes at a time.

Patient Considerations
Active Lifestyle
No exercise mode. Pump will continue to increase or decrease insulin dosing in response to changing CGM glucose levels as usual. However, insulin can be stopped at user's discretion. Pump is water resistant for up to 12 feet for 30 minutes.
Water-resistant for up to 3 feet deep for 30 minutes and light on the body, does not get in the way of activity.
Avoiding Highs and Lows
Auto basal and bolus insulin. The iLet makes the corrections for you. If you’re trending high, it will automatically give you more insulin to bring you back in range. If you’re trending low, it will reduce your current insulin dosage.
Optional glucose alerts for low and high glucose levels. Trend arrows show the direction glucose is heading, with the rate of change.
Comfort
Somewhat comfortable. Low maintenance sensor. Larger pump option.
Lowest profile sensor and smallest adhesive (about the size of two stacked U.S pennies).
Easy Insulin Dosing
Meal announcement controller. User must be carb aware. The iLet calculates and doses 100% of the insulin throughout the day and night, allowing the user to focus on other things in their lives. Please note: even when you use the "Meal Announcement." your blood glucose levels could rise above 250 mg/dL for a few hours. You'll need to be comfortable letting the iLet regulate your blood glucose.
Sensor trends can be used for dose adjustment.
Easy to Use
Easiest to Use. User weight is the only input required to start using the insulin pump. No carb counting *, correction factors, carb ratios, or pre-set basal rates required.
*User must be carb aware.
No scanning required. Minute-by-minute readings are sent directly to the mobile app.
Fewer Fingersticks
Factory-calibrated sensor. Fingersticks needed for backup only.
Factory-calibrated sensor. Finger-sticks needed for backup only.
Privacy
Discreet. Ability to check blood sugar on phone. Minimal pump interaction is required. Pump has tubing but can be clipped to clothing or placed in a pocket to be discreet when needed.
Hypoglycemia safety alarm. Discreet size but built-in hypoglycemia safety alarm alerts users when glucose is below 55 mg/dl and is always on.
