MiniMed 670G, “first of its kind” device to shake up the management of type 1 diabetes
A new hybrid closed loop system, hailed as the “first of its kind”, has been granted approval, and could significantly improve the quality of life for people with type 1 diabetes manually manage their blood sugar levels.
The MiniMed 670G has been produced by Medtronic, and has been approved by the Food and Drug Administration (FDA).
The device is a hybrid closed loop system which means it integrates smart algorithms with insulin pump and continuous glucose monitoring (CGM) technology. This allows the system to provide appropriate basal insulin doses automatically.
This is a breakthrough which could really benefit those with type 1 diabetes across the country. A healthy pancreas supplies a low, constant rate of insulin so that the body can metabolize the glucose in its blood. As those with type 1 diabetes do not have a working pancreas, the MiniMed 670G steps up to carry out this task.
The device measures blood glucose levels every five minutes and automatically administers or withholds a basal dose of insulin, depending on what the blood glucose level is at the time.
Director of the FDA’s Center for Devices and Radiological Health, Dr Jeffrey Shuren, said: “This first-of-its-kind technology can provide people with type 1 diabetes greater freedom to live their lives without having to consistently and manually monitor baseline glucose levels and administer insulin.”
A clinical trial of 123 patients with type 1 diabetes found that the device is safe, and there were no serious adverse events reported throughout the trial. This meant that the device did not do anything to cause severe low blood sugar levels (hypoglycemia), or allow blood sugars to climb dangerously high and cause diabetic ketoacidosis.
The MiniMed 670G has been approved for use by people with type 1 diabetes who are over the age of 14. Medtronic is now carrying out clinical trials to ensure the safety and effectiveness of the device in children 13 years old or younger.
This is the closest that the world has come to a true artificial pancreas being approved for the wider market.
