Summary

Dexcom G7 is a low-profile, all-in-one glucose sensor/transmitter and warms up faster than other CGMs on the market. This sensor lasts for 10 days and sends real-time glucose readings to a compatible smartphone app or directly on an Apple Watch. No finger pricks or scanning is needed. Optional low and high-blood sugar notifications are available for this system.

FDA-approved for wear on the back of the upper arm for ages 2 years and older or the upper buttocks for ages 2-17.

MARD of 8.2%

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).

Components

Dexcom G7 : 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.

Dexcom G7 : Receiver

Conveniently access glucose readings using a reader, smartphone, or directly on an Apple Watch. Phone app available for both iOS and Android devices.

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.

Device Details

Overview

Small all-in-one sensor/transmitter with a quick warm-up period and can be worn in multiple areas.

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.

Patient Considerations

Active Lifestyle

Waterproof when submerged in 2.4 meters of water and must be within 20 (unobstructed) feet of the receiver or mobile device.

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.

Avoiding Highs and Lows

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.

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.

Comfort

Low profile and low maintenance sensor application.

Somewhat comfortable. Low maintenance sensor. Larger pump option.

Easy Insulin Dosing

Real-time data and alerts make dose adjustment easier.

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.

Easy to Use

No scanning required. Readings are sent directly to the mobile app every 5 minutes.

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.
