What is Needed to Start


Pump connects tubing to a small patch called an infusion set that attaches to the body.


Sensor is inserted underneath the skin, either on the abdomen or arm.


Pump receives CGM readings and automatically adjusts insulin delivery. Data from the pump and CGM viewable on compatible smartphones (iOS and Android)

Infusion Set

An infusion set contains the thin plastic tubing that delivers insulin from the pump to the body.

Device Details

Affordability and Access

Pump coverage is not yet available. Sensor is widely covered and provided by DME and/or Pharmacy. Sensor price range; $0-$500/month.

Data Monitoring Options

Mobile App provides the ability to pull data from an iLet device to share with the Beta Bionics Cloud.

Data View Options

Data is viewed on compatible smart devices through the iLet Mobile App. You can download and view pump or CGM data on Beta Bionics Cloud.

Duration and Storage

3-day pump 10-day sensor
Sensors last 10 days and transmitters last 90 and work at 50ºF – 108ºF. Pump can be used for up to 72 hrs, battery life lasts five days with the use of CGM, and work between 36°F (2°C) to 86°F (30°C).

Patient Considerations


Low profile. Low profile/low maintenance sensor. Small tubed pump with many infusion sets to pick from.

Active Lifestyle

No exercise mode. Pump will continue to increase or decrease insulin dosing in response to changing CGM glucose levels as usual. Pump is water resistant for up to 12 feet for 30 minutes.

Avoiding Highs and Lows

Auto basal and bolus insulin. Responds to CGM data by increasing or decreasing basal insulin delivery to prevent highs and lows and maintain a target blood glucose. Bolus correction controller is available to correct high blood sugar.

Easy to Use

Easiest to Use. User weight is the only input required to start using the insulin pump. No carb counting. No correction factor. No insulin to carb ratio. No basal rate. 

Easy Insulin Dosing

Meal announcement controller. No carb counting required. User is required to “announce” a meal to the system or tell the iLet they are having a meal. Algorithm will then figure out how much insulin is needed and adapt as the system is used more. Maxiumim insulin meal doses are 24 U.

Fewer Fingersticks

Factory-calibrated sensor. Fingersticks needed for backup only.


Discreet. Ability to check blood sugar on phone or watch. Minimal pump interaction is required. Pump has tubing but can be clipped to clothing or placed in a pocket to be discreet when needed. Dexcom's built-in hypoglycemia safety alarm alerts users when glucose is below 55 mg/dl and is always on.
