Summary

Loop is a DIY (do-it-yourself) system. It takes some work to set up but allows people to think about diabetes less by automating basal insulin delivery based on predicted glucose levels. This system can be used with the Dexcom G6 and the Omnipod or Medtronic pumps. Information about DIY Loop can be found on the Loop or Riley Link websites.

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.  

Components

Loop : Pump

Loop : Pump

The system is compatible with Omnipod (left) or Medtronic (right) pumps. Both options can be applied anywhere on the body that is comfortable.

Loop : Sensor

Loop : Sensor

Automatic applicator inserts sensor just under the surface of the skin and can be applied to many places on the body.

DIY Loop : Transmitter

DIY Loop : Transmitter

RileyLink allows the pump and sensor to communicate. It is only required if a Medtronic pump is used.

Loop : Controller

Loop : Controller

Smartphone or smartwatch receives CGM readings and automatically adjusts insulin delivery via an Omnipod or Medtronic pump.

Eversense : Sensor

Eversense : Sensor

Professionally inserted by a physician during a medical visit. Minor procedure.

Eversense : Transmitter

Eversense : Transmitter

Transmitter sits outside of the body and is held on by an adhesive. Sends data every 5 minutes to a connected mobile device.

Eversense : Receiver

Eversense : Receiver

Real-time glucose measurements sent to a compatible mobile-device or smart watch. No need for a separate receiver. Available for both iOS and Android devices.

Device Details

Overview

This is a DIY (do-it-yourself) system that needs significant setup. It has the most flexibility in settings and device options. It also depends on a third device called a "Riley Link" to communicate between sensor, phone, and pump. 

Very small implantable sensor but large transmitter must be worn on top of the skin.

Affordability and Access

$$$$
Supplies can be covered for Omnipod or Medtronic pumps and Dexcom. Price range; $0-$8,574 to start and 0-$300/month. iPhone, app, and Riley link are not covered and must be set up independently. Riley link price range; $135-$165.

$$$$
Sometimes covered. Insertion and removal require a Health Care Provider. Insertion costs $100-$300, and removal costs $100-$400. Sensor and transmitter cost $800-$1400. 

Data Monitoring Options

Yes
Compatible with Tidepool - a web-based diabetes data management system. 

Yes
CGM data can upload automatically to the web-based Eversense data management system (EDMS) from the Eversense mobile app. 

Data View Options

Yes
Data can be viewed on an iPhone. 

Yes
Eversense mobile app receives and displays data in easy-to-read charts and graphs that can be shared with family and friends through the Eversense NOW app.

Duration and Storage

3-day pump 10-day sensor
Sensors last 10 days and transmitters last 90, and work at 50ºF – 108ºF. Pods or pump reservoirs last for up to 72 hrs and work from 40ºF – 104ºF.

180 Days
Sensor lasts 180 days, but a physician must implant it. Transmitter must be charged daily.

Patient Considerations

Active Lifestyle

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. *Medtronic option is not waterproof. Omnipod option is fully waterproof. 

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.

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.

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. 

Comfort

Low-profile but extra device. Low profile/low maintenance sensor. The RileyLink is an extra device that must be carried.

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

Easy Insulin Dosing

All settings are completely customizable. Can bolus from phone or smartwatch. Can operate “open-loop” where the user must enact insulin delivery based on recommendations or “closed-loop” where modifications to insulin delivery are automatically delivered.

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

Easy to Use

Difficult set-up but easy to use. Software makes most dosing decisions. Requires many parts. Can be difficult to set up. 

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

Fewer Fingersticks

Factory-calibrated sensor. Fingersticks needed for backup only.

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

Privacy

Discreet. Ability to give insulin via watch or phone. Ability to check sugar on phone or watch. Alerts available. *Medtronic pump has tubing. Omnipod is most hideable pump option (no tubes or separate controller needed).

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.
