Summary

This sensor lasts the longest - 180 days. It has to be placed under the skin by a healthcare provider. It has two parts, the implantable sensor and a transmitter that sends data to a mobile device.

 

MARD: 8.5-9.1%

*Recently FDA approved for use with insulin pumps.  

Tidepool Loop is the first fully interoperable automated insulin dosing app that originated as a patient-led initiative.

Background: A diabetes non-profit called Tidepool decided in 2018 to officially support Loop and shepherd it through the FDA process. Tidepool Loop was cleared by the FDA in January 2023 with plans to launch with Dexcom and other alternate controller-enabled (ACE) pump partners (RileyLink will no longer be necessary).

2023 Updates from Tidepool:

  • Medtronic and Tidepool have decided to discontinue the development of a Medtronic insulin pump system compatible with Tidepool Loop.
  • As Omnipod 5 is now commercially available, Insulet is devoting all available resources to their Omnipod products, including the global launch and further development of Omnipod 5.
  • Future ACE Pumps that will be commercially compatible with Tidepool Loop will need to be FDA-cleared for use with third-party interoperable automated glycemic (iAGC) controllers.

Patient Considerations

Active Lifestyle

Water-resistant transmitter when submerged in 1 meter of water for up to 30 minutes and must be within 25 feet of the connected smart device.

Automatic responses. Can set custom blood sugar targets and insulin and carb sensitivities based on type of activity. App automatically responds to blood sugar changes during activity.

Avoiding Highs and Lows

On-body vibration alerts when blood glucose levels are higher or lower than the set range. Trend arrows show the direction glucose is heading, with the rate of change. 

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

Comfort

Longest lasting sensor fits comfortably under the skin. Minor procedure is required.

Low-profile mobile app. Dosing and other adjustments can be done directly on the mobile app. 

Easy Insulin Dosing

Predictive alerts make insulin dosing easier by tracking high and low trends.

Customizable. Can bolus from phone or smartwatch and all settings are expected to be customizable. More information on modifications to insulin delivery will be available soon. 

Easy to Use

Minor procedure. Requires insertion by a physician during a medical visit. 

Easy dosing. Software makes most dosing decisions easy to do on the fly.

Fewer Fingersticks

2 daily finger-sticks are needed to calibrate the sensor. 

Factory-calibrated sensor. Fingersticks needed for backup only.

Privacy

Somewhat discreet. Tiny sensor is implanted under the skin, so the user can be discreet when needed. Ability to see sugar on watch or phone. Sensor not movable on body and requires regular meter use.

Discreet. Ability to give insulin via watch or phone. Ability to check sugar on phone or watch. Alerts available.
