The MiniMed 640G therapy management software

CareLink is the name of our family of therapy management software.


CareLink Personal software is designed for patients and is run via a website. This secure, online therapy management software downloads information from your pump which it turns into reports, allowing you to track patterns of your diabetes and therapy. As long as you have the CONTOUR® NEXT LINK meter with you (if you use a MiniMed® Veo insulin pump) or the CONTOUR® NEXT LINK 2.4 meter  (if you use a MiniMed® 640G insulin pump), you can download information from your pump at home or anywhere that you have internet access. Just like a web email account, you just register and log in.


  • To have greater control
    A clinical study has shown that people using CareLink Personal software had improved control (HbA1c) when compared to people using insulin pump therapy without CareLink Personal software1. Investigators thought that this was because of “increased contact through the internet with their diabetes care providers”.
  • To more easily identify patterns and problems
    Easy to read reports can help you understand the effects of insulin, carbohydrates and exercise on your glucose levels.
  • Work remotely with your healthcare provider
    Between visits, your healthcare provider may review your CareLink Personal software information remotely to make more accurate therapy adjustments when needed.
  • To get the most from one piece of software
    CareLink can download a large range of common blood glucose (BG) meters. Entering these into the pump (using the Bolus Wizard®) allows you to download your BG readings through the pump all in one.
  • Get a fuller picture
    Using the continuous glucose monitoring (CGM) function of your insulin pump allows you to see a full picture of your glucose trends, insulin usage, BG readings, exercise etc. all in one place – without the need for log books.

Understanding the effects of insulin doses, eating habits, exercise routines and medication on your own personal glucose levels is key to improving your diabetes control. Information is presented in simple charts, graphs and tables to help you identify patterns and problems. This can help you and your health care professional to work out the root cause of low and high blood glucose levels at particular times.

Sharing your data with your clinic

CareLink’s unique functionality allows your healthcare professional to see your data from their hospital computer. If your clinic has the CareLink Pro software you can give them permission to access your account. This allows them to link from their computer to your online account and pull your downloaded data into their records, quickly and securely.

Carelink report


CareLink Personal software makes it easier to track your blood glucose and sensor glucose levels, and to compare any changes with your daily activities and meals. The clear, simple reports contain charts, graphs and tables to show you these changes graphically and provide actual numeric values.

The list of report types that you can see may vary depending on the device(s) you have uploaded, but the descriptions below give you an overview of the different kinds of reports that you can choose from.

The most commonly used reports:

  • Quick view summary report
    Shows how your insulin delivery, your diet and your exercise patterns affect how well you are controlling your blood glucose and sensor glucose levels over a two-week period.
  • Sensor daily overlay
    Based on continuous glucose monitoring data for up to seven days. After choosing the seven days of glucose sensor tracings you want to see, this report layers each day’s report on top of each other for comparison.
  • Sensor overlay by meal
    Includes meal information recorded in the CareLink Personal logbook and data from the Bolus Wizard calculator.
  • Daily summary
    Focuses on one day and provides three graphs, including meter and sensor glucose readings, insulin usage, the carbohydrates you have eaten and your exercise routines.

Protecting your privacy and security

At Medtronic Diabetes, we care about the security of your personal information. CareLink Personal software complies with the strictest privacy regulations in the world, including Health Insurance Portability and Accountability Act (HIPAA) guidelines. The system also uses Secure Sockets Layer (SSL), a data encryption technology, which ensures that data is unreadable during the transfer.

Storing data in CareLink Personal software is often safer than storing it on a home computer system that is connected to the Internet. We use a three-tier architecture that puts the data behind three separate firewalls.
