Summary

The twiist AID system was cleared by the FDA for use with CGMs that have received FDA designation as integrated continuous glucose monitors (iCGMs). As the twiist AID system gets closer to commercial availability, Sequel Med Tech will publicize the list of compatible CGM

*Recently FDA approved for people with type 1 diabetes ages 6 and up.

The Tandem Mobi is the smallest durable automated insulin delivery system available in the U.S. that can be fully controlled by a mobile device. The pump is equipped with an on-pump button for users to bolus insulin directly from the pump if they don’t want to do it from their phone. This system is combined with the Dexcom continuous glucose monitor (CGM) to automatically adjust insulin delivery in response to glucose trends. 

*Compatiblilty with Dexcom G7 now available

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. The pump and CGM are waterproof and can be worn for most exercises.

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.

Auto basal and bolus insulin. Responds to CGM data by increasing or decreasing basal insulin delivery to prevent highs and lows and maintain a set blood glucose target. 

Comfort

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

Shorter tubing option. A shorter 5-inch tubing option for comfort on body. 

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

Automatically adjusts dosing. Sensor integration allows the pump to automatically adjust insulin doses. More customizable dosing than pens or syringes. Manual bolus button is available for quick dosing without a phone. 

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.

Easy Dosing. Full control from a smartphone, with the option to manually bolus if needed.

Fewer Fingersticks

Factory-calibrated sensor. Fingersticks needed for backup only.

Factory-calibrated sensor. Fingersticks needed for backup only.

Privacy

Discreet. The pump is in two pieces - the top (algorithm and battery) and the bottom (insulin chamber and AVS technology)

Discreet. Ability to check blood sugar on phone or watch. Ability to bolus on a compatible smartphone. Pump has tubing but can be clipped to clothing or attached to local area with an armband or adhesive sleeve 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.
