Beta Bionics iLet Pancreas
Dexcom G6
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).
This sensor lasts for 10 days and only needs finger sticks as a backup. Dexcom G6 has 3 parts - sensor, transmitter, and receiver. Data can be viewed on a compatible mobile device or a separate receiver. Optional low and high blood sugar notifications are available for this system.
FDA approved for insertion on the abdomen (indicated for patients age 2 years and older) or the upper buttocks (ages 2-17 years).

Components
Infusion Set
An infusion set contains the thin plastic tubing that delivers insulin from the pump to the body.
Controller
Pump receives CGM readings and automatically adjusts insulin delivery. Data from the pump and CGM viewable on compatible smartphones (iOS and Android)
Sensor
Sensor is inserted underneath the skin, either on the abdomen or arm.
Pump
Pump connects tubing to a small patch called an infusion set that attaches to the body.
Receiver
Receives data automatically from the transmitter. Can be substituted by compatible smartphone and smartwatch. Available for both iOS and Android devices.
Transmitter
Sends readings from sensor to device, clips into sensor. Can be used for 90 days.
Sensor
Sensor uses a thin, flexible filament inserted just under the skin to measure glucose levels every 5 minutes. Push-button applicator allows sensor to be placed on the body in one step.
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.
Small sensor can be worn in multiple areas.

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
Automatically and continuously sends data to the user’s Dexcom Clarity web-based cloud which is accessible by clinicians. Data upload is possible with Glooko and Tidepool data-management systems.
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
Users must download the Dexcom G6 and Dexcom Clarity apps to view and share data. Both apps provide multiple data views, sharing options, and access through the clinician portal using a code from the user's device. Caregivers can use the Dexcom Follow app to view data. Glooko and Tidepool can also be used to view data.
Duration and Storage

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 when submerged in 2.4 meters of water and must be within 20 (unobstructed) feet of the receiver or mobile device.
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.
Custom alerts can be set for highs, lows, and rapidly rising or falling glucose levels. Trend arrows show the direction glucose is heading, with the rate of change.
Comfort
Somewhat comfortable. Low maintenance sensor. Larger pump option.
Low profile and low maintenance sensor application.
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.
Real-time data and alerts make dose adjustment easier.
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.
Flexible pump integration. Can be paired with multiple different types of pumps which gives flexibility for how to use the data.
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 but built-in hypoglycemia safety alarm alerts users when glucose is below 55 mg/dl and is always on.
