What is Needed to Start
Pump
Pump connects tubing to a small patch called an infusion set that attaches to the body.
Sensor
Sensor is inserted underneath the skin, either on the abdomen or arm.
Controller
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
$$$$
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.
Data Monitoring Options
Yes
iLet Mobile App provides the ability to pull data from an iLet device to share with the Beta Bionics Cloud.
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.
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).
Vision / Auditory / Dexterity
NO text to speech
YES vibration alerts
A LOT of dexterity needed
Patient Considerations
Comfort
Somewhat comfortable. Low maintenance sensor. Larger pump option.
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.
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.
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.
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.
Fewer Fingersticks
Factory-calibrated sensor. Fingersticks 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.
Frequently Asked Questions
Where can I read up to date evidence about iLet?
"In youth 6–17 years old with T1D, use of insulin-only configuration of BP improved HbA1c, TIR, and hyperglycemic metrics without increasing CGM-measured hypoglycemia compared with standard of care. Improvement in glycemic metrics was most pronounced in participants with high baseline HbA1c levels."

Messer LH., et al.
"In adults with T1D, HbA1c was improved with the BP using fast-acting insulin aspart compared with standard care without increasing CGM-measured hypoglycemia. However, the effect was no better than the reduction observed with the BP using aspart or lispro."

What type of insulin is compatible with the iLet?
iLet pumps and cartridges are indicated for use with Novolog and Humalog U-100 insulins, and Fiasp® PumpCart® 1.6 ml prefilled cartridges.
The safety and efficacy of other insulins have not been established for use with iLet pumps.
