Patient Considerations

Active Lifestyle

Waterproof. The pump, when connected to the cassette, has a rating of IP28, indicating protection from continuous immersion in water. The pump can tolerate immersion to depths of up to 12 feet (3.7 m) for 1 hour.

Waterproof when submerged in 2.4 meters of water and must be within 20 (unobstructed) feet of the receiver or mobile device. This device is intended to help people with non-insulin requiring type 2 diabetes better understand their blood sugar numbers. 

Avoiding Highs and Lows

Automatically adjusts insulin delivery. Increases or decreases insulin delivery to meet glucose targets. Insulin delivery settings can be aggressive or conservative.

Very limited alerts. This device does not provide alarms and alerts for high, low, and rise/fall rates. This device is intended to track and understand the effects of food on blood sugar for people with type 2 diabetes.

Comfort

Low-profile. Low profile with an adhesive design that prevents the pump from catching on other objects. 

Low profile and low maintenance sensor application.

Easy Insulin Dosing

Customizable. Can bolus from phone, smartwatch, or directly from the device without needing to be attached to your phone. The device also directly measures the volume (amount) and flow (speed) of insulin delivered with every micro-dose

No options. Stelo is intended for use by people with type 2 diabetes who do not require insulin to manage their blood sugar levels. 

Easy to Use

Watch compatible. The twiist AID system is the first FDA-approved AID system that can be directly controlled from an Apple Watch.

Real-time data and alerts make dose adjustment easier.

Fewer Fingersticks

Factory-calibrated sensor. Fingersticks needed for backup only.
