Medtronic’s Guardian Connect CGM Gets FDA Approval


DUBLIN, IRELAND – Medtronic’s Guardian Connect continuous glucose monitoring system (CGM) has received FDA approval, expanding CGM options for people living with diabetes from the most recent Dexcom G5 and Abbott’s Freestyle Libre system. It is “the first smart standalone CGM system to help people with diabetes stay ahead of high and low blood glucose events” as it transmits directly to the iPhone without using another receiver.

The standalone CGM is comprised of three parts: a thin sensor, a small plastic transmitter attached to the sensor and the Guardian Connect app on a compatible iOS device. The Guardian Connect system is designed to help people, aged 14 to 75, using multiple daily injections (MDIs), and is the only one on market to give alerts for potential high or low blood glucose events up to 60 minutes in advance.

“The FDA approval of the Guardian Connect system fills a key gap that exists in diabetes treatment today—how to predict dangerous blood glucose highs and lows so they can be potentially avoided,” said Annette Brüls, president, Diabetes Service and Solutions at Medtronic. “With predictive alerts and the Sugar.IQ assistant, the Guardian(TM) Connect system enables people to proactively manage their diabetes, so they can focus on living their life, not constantly worrying about their blood glucose levels.”

The CGM uses the Using Guardian(TM) Sensor 3, the same sensor used in Medtronic’s 670G hybrid closed-loop system. In studies, it was found that the system accurately alerted patients of 98.5 percent of hypoglycemic events.2

Benefits of the Guardian Connect system include:

  • Customized one hour predictive alerts – from 10 minutes up to one hour ahead gives you time to respond
  • Free 24-hour SMS alerts (and up to five care people)
  • Easy to share blood glucose readings with family and friends
  • Reduced risks of hypoglycemia and more time “in-range”
  • Sleek design – marketed for an active lifestyle, half the weight of other real-time CGM systems on the market
  • Water proof – can be submerged for up to 2.4 meters (7.5 feet) for 10-minute periods
  • Access to the Sugar.IQ system – smart diabetes assistant that looks at what affects blood glucose levels (BGLs)
  • Rechargeable, re-useable, long-life technology

The Guardian Connect does not work with insulin pumps, however, automatic syncing shares easy to interpret data with your healthcare professional.

Available soon, the Guardian Connect system is believed to hit markets by July 2018, and as early as May 2018.

About Sugar.IQ system

People using the Guardian Connect system will also have exclusive access to the groundbreaking Sugar.IQ(TM) smart diabetes assistant, empowering them to further address the daily challenges of diabetes. With artificial intelligence technology from IBM Watson Health, the Sugar.IQ assistant continually analyzes how an individual’s blood glucose levels respond to their food intake, insulin dosages, daily routines and other factors3. Together with the Guardian Connect system, the Sugar.IQ assistant can turn difficult-to-determine patterns into personalized, actionable insights that help people with diabetes keep blood glucose levels in their target range.

About Continuous Glucose Monitoring (CGM)

A CGM is a small wearable device that tracks your blood glucose throughout the day and night, notifying you of highs and lows so you can take control of your blood glucose levels.

The CGM can be placed in several areas of your body, depending on what is most comfortable for the user. The most popular places for a CGM tend to be around the stomach, back of the arms and legs. Avoid spots where your body naturally bends a great deal, where clothing might cause irritation or be a burden.

The process of inserting the CGM is easy and virtually painless. For seven days (longer if you are able to keep the adhesive for sticking), you can have direct access to your blood sugars throughout the day and night.

The CGM consists of three basic parts:

  • wireless display device (or receiver) –  has a screen where you can check your current blood glucose level, look at past data over a span of 24 hours, and get trends about whether blood glucose is likely to go up or down, and how fast.
  • transmitter –  is the small piece that fits onto the sensor and sends blood glucose information data wirelessly to your display device.
  • sensor – is inserted just underneath the skin, is thinner than a needle and roughly half an inch long. The sensor remains in the skin for several days, detecting blood glucose information.
