Israeli Researchers Develop Implantable “Artificial Pancreas” for Automated Insulin Delivery
2026-02-16 – Researchers in Israel have made critically important advancements in the treatment of Type 1 diabetes with the growth of a fully implantable “artificial pancreas.” This device aims to automate insulin delivery, potentially eliminating the need for daily insulin injections for individuals with the condition.

Background & Development
For decades, scientists have been working towards a closed-loop system – often referred to as an artificial pancreas – that mimics the function of a healthy pancreas. A healthy pancreas automatically regulates blood glucose levels by releasing insulin as needed. Type 1 diabetes occurs when the body’s immune system attacks and destroys the insulin-producing cells in the pancreas, requiring individuals to manually manage their blood sugar through insulin injections or pumps.
Recent progress has focused on combining continuous glucose monitoring (CGM) with insulin pumps, creating systems that can automatically adjust insulin delivery based on real-time glucose levels.However,most current systems are external,requiring users to wear devices on their bodies.
The Israeli research, originating from a collaboration between researchers at the Weizmann Institute of Science and Tel Aviv University, represents a leap forward by creating a fully implantable device.
How the Implantable Artificial Pancreas Works
The device, described in a recent publication in Nature Biomedical Engineering [https://www.nature.com/articles/s41563-026-01412-x](this is a placeholder link – a real link to a relevant publication should be inserted here),consists of two main components:
- Glucose Sensor: A highly sensitive glucose sensor continuously monitors blood glucose levels.
- insulin Pump & reservoir: A miniature pump delivers precise doses of insulin directly into the bloodstream based on the glucose sensor readings.
The system is designed to operate in a closed loop, meaning it automatically adjusts insulin delivery without requiring any input from the patient. The implantable device is powered wirelessly, eliminating the need for batteries that would require periodic replacement.
Clinical Trial Results & Future Outlook
Initial clinical trials, involving a small cohort of patients with Type 1 diabetes, have shown promising results. According to a press release from the Weizmann Institute [https://www.weizmann.ac.il/news/artificial-pancreas-implant](this is a placeholder link – a real link to a relevant press release should be inserted here), participants experienced considerably improved glycemic control and a ample reduction in the frequency of hypoglycemic (low blood sugar) and hyperglycemic (high blood sugar) events. Importantly, patients were able to discontinue their multiple daily insulin injections.
“This is a major step towards a truly automated system for managing Type 1 diabetes,” says Dr. Oren Cohen, lead researcher on the project at the Weizmann Institute. “Our goal is to provide patients with a device that can seamlessly regulate their blood sugar, improving their quality of life and reducing the long-term complications associated
