Diabetes patients might find relief from life-threatening low blood sugar levels with the help of a new implantable device.
**Revolutionary Implantable Device Developed for Emergency Hypoglycemia Treatment in Type 1 Diabetes**
A groundbreaking device, developed by a team at the Massachusetts Institute of Technology (MIT), promises to revolutionise the management of hypoglycemia in Type 1 diabetes patients. This quarter-sized implant, designed to be placed under the skin, automatically releases glucagon when blood sugar levels drop dangerously low[1][2][4].
### Design and Mechanism:
The device's core comprises a 3D-printed polymer reservoir filled with powdered glucagon, a more stable form for long-term storage than liquid[1][2][3]. The reservoir is sealed with a nickel-titanium shape-memory alloy (SMA), a material that changes shape when heated to approximately 40°C. This shape change releases the glucagon stored inside[1][2]. The SMA is activated wirelessly through an antenna that receives radiofrequency signals, generating a small electrical current to heat the alloy and trigger drug release[2].
### Testing and Performance:
In tests on diabetic mice, the device reliably released glucagon within 10 minutes of hypoglycemia onset, successfully stabilising blood sugar levels[2][3]. The researchers demonstrated the device's fast response and effective prevention of dangerously low blood sugar during testing. Beyond glucagon delivery, the same technology showed promise for delivering other emergency drugs such as epinephrine, suggesting potential for broader emergency treatments[2].
### Potential Lifespan:
While exact human lifespan data is yet to be published, the use of powdered glucagon rather than liquid increases stability and extends the device's functional lifespan compared to current emergency glucagon kits. The implant is designed for long-term use, remaining under the skin for extended periods and ready to act whenever needed[1][4]. Future clinical assessments will determine the device's durability and how often it would require replacement or glucagon refilling.
### Benefits and Impact:
The device could reduce the need for emergency glucagon injections, which are currently difficult to administer during hypoglycemic episodes, especially in children or unconscious individuals[1][4]. It offers automated protection against hypoglycemia, potentially reducing the risk of seizures, unconsciousness, and death associated with dangerously low blood sugar. It may also alleviate the constant fear of hypoglycemia experienced by many Type 1 diabetics and their caregivers[4].
This implant represents a major advancement in hypoglycemia management for Type 1 diabetes, combining stable drug storage with smart, wireless-triggered delivery to provide rapid, reliable emergency treatment[1][2][3][4]. The devices were kept implanted for up to four weeks, and the researchers plan to extend this time up to at least a year.
Hypoglycemia, or low blood sugar, can lead to confusion, seizures, and is fatal if untreated. Epinephrine is a drug used to treat heart attacks and prevent severe allergic reactions, including anaphylactic shock. The researchers hope to begin testing the device in clinical trials within the next three years.
Most patients with Type 1 diabetes use daily insulin injections to help their body absorb sugar and prevent their blood sugar levels from getting too high. The shape-memory alloy is programmed to change its shape when heated, releasing the glucagon from the reservoir. The device can be triggered manually or automatically by a sensor. Each device can carry either one or four doses of glucagon. Glucagon is a hormone that stimulates the liver to release glucose into the bloodstream to combat hypoglycemia.
In diabetic mice, activating the glucagon release from the device prevented hypoglycemia within less than 10 minutes. The device can be designed to release drugs when blood sugar drops below a certain level, interfacing with continuous glucose-monitoring technology. Some patients may not realise they are becoming hypoglycemic, making it difficult to counteract the condition. The device offers a lifesaving solution for these situations.
