MIT's Implantable Device to Revolutionize Diabetes Care, Preventing Hypoglycemia Without Injections
August 11, 2025
Researchers at the Massachusetts Institute of Technology (MIT) are developing a groundbreaking implantable device designed to prevent hypoglycemia in diabetes patients.
This innovative device automatically releases glucagon, providing a critical safeguard against life-threatening hypoglycemia, particularly for those with Type 1 diabetes.
The project has received funding from notable organizations, including the Leona M. and Harry B. Helmsley Charitable Trust and the National Institutes of Health.
The research team aims to extend the device's operational lifespan to at least one year, with plans for further animal studies and eventual clinical trials within the next three years.
In initial animal testing, the device successfully stabilized blood sugar levels in diabetic mice within just 10 minutes of activation, and it also showed potential for delivering epinephrine.
Measuring roughly the size of a quarter and weighing less than 2 grams, the device utilizes a shape-memory alloy to release powdered glucagon when activated by heat.
Tests simulating conditions that typically induce hypoglycemia, such as missed meals, demonstrated that the device effectively raised blood glucose levels above hypoglycemic thresholds within one hour after glucagon release.
This development not only promises to assist diabetic patients but could also pave the way for new methods of delivering emergency medications more broadly.
Experts have highlighted the pressing need for improved glycemic control in diabetes, noting that current glucagon delivery methods have significant limitations that this new device could address.
Designed for subcutaneous placement, the device can be activated in emergencies without injections, offering a vital solution for patients who may not recognize their low blood sugar levels.
Daniel Anderson, a professor at MIT, emphasized that the device's capability to deliver stable dry powder glucagon without patient intervention represents a promising emergency rescue option.
This innovation is especially beneficial for children with diabetes and during nighttime hypoglycemic events, alleviating fears associated with hypoglycemia for both patients and their families.
