Introducing The Next Generation ofContinuous Glucose Monitoring

 The GlySens Eclipse 3
nothing attached to the body  -  lasts for years 

Nothing on the Body

Unlike existing CGM devices that must be adhered to the skin, the GlySens Eclipse 3 CGM is fully implantable.  There is nothing visible on the body

Long-Term Duration

Device life is measuring in years - not days. The Eclipse 3 is capable of running for more than 2 years without needing replacement

Entirely Continuous

The Eclipse 3 is always measuring and transmitting glucose readings to the user's phone

Fully Interoperable

The implant has on-board Bluetooth for seamless connectivity to insulin pumps, smart pens, and other connected health applications

Built with Innovative Technology Based on  Strong Science

Developed over many years, the Eclipse 3 sensor employs a number of unique and groundbreaking technologies to ensure a long lasting and accurate device

  • Unique Sensing Engine

    GlySens uses a fundamentally different approach to measure glucose 

    Oxygen Based Glucose Sensing
    Unlike conventional CGMs, GlySens technology relies on measuring oxygen rather than hydrogen peroxide as a signal for glucose. This difference allows the sensor to be protected from the tissue environment, enabling the sensing engine to run for years rather than days and be insensitive to interferents.

    Multi-Channel Array
    Rather than a single point measurement of glucose, the Eclipse 3 utilizes a redundant array of detectors to ensure a highly accurate measurement resistant to artifacts and noise.

    3 Electrode Electrochemical Cell
    GlySens employs a stable 3-electrode cell rather than the widely used and quick to degrade 2-electrode system allowing the implant to run for extremely long durations.

  • Designed for Long Term Use

    GlySens has developed and implemented a number of innovative solutions allowing the implant to operate for durations measured in years rather than days.

    Anti-Inflammatory Drug Elution
    An anti-inflammatory drug eluting membrane integrated onto the implant ensures a healthy tissue environment for the life of the device. This allows the implant to accurately measure glucose in the face of the body's foreign body response.

    Stabilized Enzymes
    State of the art immobilization methods have been implemented allowing the enzymes needed for sensing to remain active for periods unheard of in other devices and applications.

    Easily Replaceable
    When it's time for a replacement, a new sensor can be implanted into the same tissue space formed by the first device making the whole process quick and easy.

  • Fully Integrated

    No need for any body-worn components. Everything needed to measure and report glucose is built into the implant itself. 

    Integrated Power
    Implant grade high density battery integrated into the implant allows for continuous operation for over two years without recharging or replacement.

    Direct Connectivity
    Bluetooth Low Energy built into the implant allows it to connect directly to devices outside the body, be it a phone or a watch or an insulin pump, enabling Automated Insulin Delivery and communication with other connected health applications through secure protocols.

    Embedded Algorithms
    All glucose calculation algorithms run on the implant's embedded microprocessor allowing the device to transmit a glucose measurement via Bluetooth without any processing needing to occur elsewhere.

Bruce Buckingham, MD

Dr. Bruce Buckingham received his medical degree from University of California at San Diego. He completed his internship, residency, and fellowship at Children’s Hospital of Los Angeles. He is currently a Professor in the Department of Pediatric Endocrinology at Stanford Medical Center and the Stanford Children’s Hospital. His research focuses on continuous glucose monitoring in children and closed-loop (artificial pancreas) systems. He has collaborated on various overnight and 24-hour closed-loop platforms in development and has helped to develop algorithms for detecting infusion set and sensor failures and to improve infusion set wear duration.
Dr. Buckingham is well recognized as a leading expert in the real-world application and clinical use of continuous glucose monitoring systems.

Daniel Einhorn, MD

Dr. Daniel Einhorn is medical director of the Scripps Whittier Diabetes Institute, clinical professor of medicine (voluntary) at UC San Diego, president of Diabetes and Endocrine Associates, and associate editor of the Journal of Diabetes. He is a trustee and past-president of the American College of Endocrinology (ACE), a founding member and regent of the ACE Foundation, and past-president of the American Association of Clinical Endocrinologists (AACE). He received his BA at Yale (Summa cum Laude), his MD at Tufts (AOA) and his post-graduate training at Harvard.
