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).
Traditional syringe and needle. The most affordable insulin delivery option.
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.
Syringe and Vial : Bolus Insulin
Bolus (fast-acting) insulin vial for meal time or high blood sugar correction.
Syringe and Vial : Basal Insulin
Basal (long-acting) insulin vial for steady release of insulin that helps control blood sugar between meals, and overnight.
Syringe and Vial : Needles
Classic syringes with plunger used to fill insulin for injection
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.
Nothing on the body when not in use but very visible when dosing.
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.

28 Days
Open vials can be stored at room temperature (not above 80º F) for up to 28 days. Unopened vials should be stored in the refrigerator (36ºF - 86ºF.)
Vision / Auditory / Dexterity

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.
Limited Adjustability. No way to adjust long-acting insulin for higher activity on the fly.
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.
Limited customizability. Requires a high level of engagement and effort to avoid highs and lows but can be paired with a CGM for improved blood sugar control.
Comfort
Somewhat comfortable. Low maintenance sensor. Larger pump option.
Many components. Must carry insulin vials and large syringes but nothing attached to the body.
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.
Requires attention. You have to do the math to figure out your dose. Unable to adjust basal in real-time.
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.
Many steps. Requires effort to figure out doses and deliver insulin every single time you need it.
Fewer Fingersticks
Factory-calibrated sensor. Fingersticks needed for backup only.
Frequent finger-sticks are required.
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.
Hideable. Vials and syringes can be hidden when not in use but very visible when in use. Frequent injections are unavoidable.
