Diabetic patients may be protected from life-threatening low blood sugar levels through the use of a new implantable device.
In a groundbreaking development, researchers at the Massachusetts Institute of Technology (MIT) have created an implantable glucagon reservoir designed to provide emergency treatment for hypoglycemia in Type 1 diabetes patients. The device, about the size of a quarter, is a promising advancement in preventing severe hypoglycemia, especially during sleep or unconsciousness, by offering rapid, reliable glucagon delivery without injections.
The study, published today in Nature Biomedical Engineering, was led by Siddharth Krishnan, a former MIT research scientist, and senior author Daniel Anderson, a professor at MIT. The research was funded by the Leona M. and Harry B. Helmsley Charitable Trust, the National Institutes of Health, a JDRF postdoctoral fellowship, and the National Institute of Biomedical Imaging and Bioengineering. This work was carried out, in part, through the use of MIT.nano's facilities.
The implantable device is a quarter-sized device containing a 3D-printed polymer reservoir storing powdered glucagon, which remains stable longer than liquid forms. The reservoir is sealed with a nickel-titanium shape-memory alloy that changes shape when heated to 40°C, releasing the glucagon dose when triggered wirelessly by a radiofrequency signal.
In tests with diabetic mice, the device effectively reversed dangerously low blood sugar within 10 minutes. It can store either one or four doses and remained functional for up to four weeks in these trials. The device works even after fibrotic tissue forms around the implant, a common issue with implanted devices. The implant could also be triggered automatically by wearable glucose monitors, enabling a closed-loop emergency response without patient intervention.
Regarding future plans, researchers aim to extend the device’s lifespan to at least one year and hope to begin clinical trials within three years. They also envision integration with existing continuous glucose monitoring systems for automated activation during hypoglycemic events. The device can also be used to deliver emergency doses of epinephrine.
This implantable reservoir represents a significant step forward in managing Type 1 diabetes, offering patients a reliable emergency backup for hypoglycemia. The device's goal is to protect patients from low blood sugar and relieve the fear of hypoglycemia.
