Medtronic to Study New 7-Day Infusion Sets for Insulin Pumps

The U.S. Food and Drug Administration (FDA) approved Medtronic to study a new longer-lasting infusion set for insulin pumps.

The study will enroll up to 150 people with type 1 diabetes aged 18 to 80. Users will wear Medtronic’s MiniMed 670G system for up to 7 days in the trial. 

Up to now, pumps could only be worn for 2 to 3 days, causing disruptions and time-consuming changing out of infusion sets. The new sets will allow users to wear the pumps for longer due to:

  • New adhesive technology
  • Maintaining insulin stability

What is an insulin pump?

Insulin pumps come in handy for those who have to take insulin around the clock. With an insulin pump, you receive a continuous delivery of short-acting basal insulin throughout the day. Pumps eliminate the need for injecting insulin.

An insulin pump can also be programmed to deliver larger doses of insulin at meal times. 

The pump is about the size of a smartphone and worn on the outside of your body. When starting on an insulin pump, you will need to get training from your diabetes care team on ways to use the pump and prevent emergencies


Types of insulin pumps

There are two main kinds of insulin pumps: traditional pumps and patch pumps. Traditional pumps are worn outside the body and attach to the body via tubing and an infusion set. 

Patch pumps contain everything you need in a small patch that’s worn on the body. You control a patch pump though a separate wireless device that lets you program mealtime (bolus) insulin doses from the patch. 

Some insulin pumps can connect wirelessly either to a CGM or a blood glucose meter so that you can better manage your insulin dosage based on blood sugar levels.

What’s an infusion set?

The infusion set is the part that connects the insulin pump to the skin using a tiny needle. It works like an IV. Many infusion sets come with an insertion device that helps you connect it to your skin with the push of a button. 


Types of infusion sets

The two main types of infusion sets are angled and straight. Angled infusion sets are inserted at a 30 degree angle and sit laterally under the skin. 

Straight sets are inserted at a 90 degree angle perpendicular to the skin and usually come with an insertion device. 

Making type 1 easier

If approved, these extended-wear infusion sets could make managing diabetes a lot easier and less time consuming for those with type 1. In addition, when used with Medtronic insulin pumps that include 7-day continuous glucose monitors (CGMs), the infusion set and the sensor could be changed out at the same time, making the pump even more user-friendly and time-saving.
