Diabetes Technology: CGMs, Insulin Delivery Devices and Glucagon Products

Updated April 29, 2026

New insulin pumps, infusion devices, continuous glucose monitors (CGMs), and smartphone apps continue to enter the market. These technologies offer a range of options for people living with type 1 and type 2 diabetes, depending on their individual needs, treatment plan, lifestyle, and preferences.

This information is provided for educational purposes only and does not represent an endorsement of any vendor, product, or device. Patients should always talk with their diabetes care team to determine which technology is appropriate for them.

Continuous Glucose Monitors (CGM)  

“Many of our patients, with both type 1 and type 2 diabetes, have experienced drastic improvements to their blood glucose control by starting to use a CGM.”

Dexcom G7 - 10-day Sensor

The Dexcom G7 is available for people with type 1, type 2, or gestational diabetes. The sensor is 60% smaller than the Dexcom G6 and is typically worn on the upper arm. Children ages 2 to 6 should wear it on the upper buttocks.

The G7 provides real-time glucose data to a smartphone or smartwatch without routine fingersticks. The all-in-one sensor and transmitter take 30 minutes to warm up. The sensor continuously measures glucose levels and sends real-time data every five minutes. It can sound an alarm when readings become too high or too low.

The G7 includes Quiet Mode, Delayed First Alert, Urgent Low Alert, and Urgent Low Soon Alert. It also has a 12-hour grace period after the 10-day wear period before the sensor stops working.

Dexcom G7 - 15-Day Sensor

The Dexcom G7 15-Day Sensor is slightly more accurate than the 10-day sensor because it uses a different algorithm. It has a 60-minute warm-up period.

The sensor continuously measures glucose levels and sends real-time data every five minutes. It can sound an alarm when readings become too high or too low. The G7 includes Quiet Mode, Delayed First Alert, Urgent Low Alert, and Urgent Low Soon Alert. It also has a 12-hour grace period after the 15-day wear period before the sensor stops working.

Both the 10-day and 15-day versions integrate with various insulin pumps, but not all pumps.

FreeStyle Libre 3 Plus

The FreeStyle Libre 3 Plus is a 15-day sensor approved for people ages 2 and older. It provides glucose data every minute and eliminates the need for routine fingersticks.

The sensor is worn on the upper arm and sends real-time readings to a smartphone app. It offers optional high- and low-glucose alerts. The urgent low alarm at 55 mg/dL cannot be turned off. The smartphone app also allows users to share data with family members and/or care team members.

The Libre 2 Plus and Libre 3 Plus integrate with various insulin pumps, but not all pumps.

Eversense 365

The Eversense 365 sensor is implanted in the upper arm by a medical professional and must be replaced annually. The system includes an implantable sensor, a transmitter worn over the implant site, and a mobile app.

The transmitter must be charged daily and calibrated by fingerstick. Eversense 365 is approved for adults ages 18 and older. It integrates with the twiist insulin pump.

Medtronic Simplera

The Medtronic Simplera sensor is used with the MiniMed 780G insulin pump. It is a 7-day sensor that integrates with the pump to help adjust insulin delivery.

Abbott Instinct

The Abbott Instinct sensor is used with the MiniMed 780G insulin pump and is similar to the Libre 3 Plus. It is a 15-day sensor that integrates with the pump to help adjust insulin delivery.

Insulin Pumps 

Most automated insulin pumps adjust background, or basal, insulin based on sensor glucose readings to help prevent both hyperglycemia (high blood sugar) and hypoglycemia (low blood sugar).

t:slim X2 Insulin Pump with Control-IQ Technology

The t:slim X2 is a touchscreen insulin pump that integrates with the Dexcom G7 10-day sensor and FreeStyle Libre 3 Plus CGM. Integration with the Dexcom G7 15-day sensor is anticipated within the year. Free software upgrades are available for download.

The Control-IQ closed-loop feature predicts glucose levels 30 minutes in advance and automatically adjusts basal rates to help prevent high and low blood sugar. It can also deliver an automatic micro-correction bolus every hour.

Tandem currently makes the only automated pumps that allow users to select an extended bolus and a temporary rate while in automated mode.

Tandem’s t:connect mobile app displays the insulin pump screen on a smartphone, including current glucose and insulin on board. It also allows users to administer a bolus. Data automatically uploads to t:connect so the care team can access it during office visits or when patients call with a question.

Tandem Mobi

Tandem Mobi is the world’s smallest durable automated insulin delivery system and is approved for ages 6 and older. The pump is fully controlled through an iPhone or Android mobile app and does not have a screen on the pump itself.

Tandem Mobi uses Control-IQ technology and pairs with the Dexcom G7 10-day sensor. Integration with the Dexcom G7 15-day sensor is anticipated within the year.

The system predicts glucose levels 30 minutes in advance and adjusts insulin delivery every five minutes to help prevent high and low blood sugar. It can also deliver automatic insulin correction boluses every hour. Users can still bolus for snacks and meals using their smartphone.

Tandem Mobi contains a 200-unit insulin cartridge, even though it is less than half the size of the t:slim X2. Detachable infusion sets are compatible with all existing Tandem infusion sets, allowing users to mix and match infusion sites and tubing lengths.

A tubeless version is expected to be released within the year.

MiniMed 780G Hybrid Closed Loop System

The MiniMed 780G is approved for people with type 1 diabetes ages 7 and older. The SmartGuard Automation system delivers basal insulin every five minutes and continuously self-adjusts to help prevent highs and lows.

The MiniMed 780G integrates with either the Simplera or Instinct sensor. It connects directly to compatible smartphones and Apple Watch, allowing users to view glucose trends and insulin delivery status.

Bolus delivery is not available through the smartphone app. However, when the phone app is used, data can be shared with the health care team through CareLink.

MiniMed currently offers a 7-day extended infusion set.

MiniMed Flex

MiniMed Flex has been approved, with release expected in summer 2026. It is a small, screenless, tubed insulin pump that uses the same SmartGuard Automation system as the MiniMed 780G.

MiniMed Flex has a 300-unit reservoir, a 7-day extended infusion set, and a rechargeable battery. It is controlled through the MiniMed Mobile app.

Omnipod 5

Omnipod 5 is a tubeless, automated insulin delivery system approved for people ages 2 and older with type 1 diabetes. The pump integrates with the Dexcom G7 and Libre 2 Plus sensor. Integration with the Libre 3 Plus is anticipated within the year.

A handheld controller operates the pump. Some Android smartphones and iPhones also support the Omnipod 5 app, allowing some users to operate the system without a separate controller. When using the Libre 2 Plus sensor, users must use the Omnipod 5 Controller.

Omnipod 5 adjusts insulin delivery based on a predicted glucose level 60 minutes in the future, helping protect against high and low blood sugar.

Beta Bionics iLet

The Beta Bionics iLet system fully automates insulin dosing. It is compatible with NovoLog, Humalog, and Fiasp insulin.

The iLet pairs with Dexcom G7 10-day and 15-day sensors and the FreeStyle Libre 3 Plus. It manages glucose levels using only a meal announcement: usual, less than usual, or more than usual.

The only information required for setup is the user’s weight. Carb counting is not required. Bolusing, correction factors, insulin-to-carb ratios, and preset basal rates are also not required.

A tubeless version is expected within the year.

twiist Automated Insulin Delivery System

The twiist automated insulin delivery system is a tubed pump currently available only through prescription benefit. It integrates with either the FreeStyle Libre 3 Plus or Eversense 365 CGM.

The system allows personalized glucose targets ranging from 87 to 180 mg/dL. It includes a food emoji library that lets users select options based on how foods affect their glucose levels. Users can also edit carb intake after meals if they ate more or less than planned.

The system is designed to detect blockages sooner than other pumps. It works with the iPhone and Apple Watch app and uses the Tidepool Loop algorithm to adjust insulin delivery based on CGM data.

Other Insulin Delivery Devices

InPen by Medtronic

InPen is a reusable smart insulin pen that connects with smartphones. The half-unit refillable pen helps calculate doses and track injection data. Based on information entered by the user, it can calculate doses using insulin-to-carb ratios, meal size, or number of servings.

InPen is an option for people who take multiple daily injections but do not want to wear an insulin pump. It can also be used as a backup for pump users or by people who want to take a break from using a pump.

V-Go Insulin Delivery Device

V-Go is a patch pump for people with type 2 diabetes who require multiple daily injections. It delivers automatic basal insulin, and the user clicks for mealtime insulin. The device must be changed daily.

CeQur Simplicity Patch

CeQur Simplicity is a four-day wearable patch that delivers injection-free mealtime insulin. One click delivers two units of rapid-acting insulin for on-demand meal dosing and bolus correction. Users must still take basal insulin.

Glucagon Delivery Devices

Glucagon is the standard of care for treating severe hypoglycemia, or severe low blood sugar. Lilly’s standard mix kit was the only source of glucagon for decades, but it is no longer available. It has been replaced by the following products.

Gvoke HypoPen and Zegalogue Glucagon Injection

Both Gvoke and Zegalogue treat severe hypoglycemia, but they have different characteristics.

Gvoke is an EpiPen-style glucagon injection available as a prefilled syringe or autoinjector. It can be used for people ages 2 and older.

Zegalogue is a glucagon receptor agonist available as a prefilled autoinjector or syringe. It is approved for people ages 6 and older.
