Implantable Long-Term CGM Solutions
Introduction
Implantable long-term continuous glucose monitoring (CGM) systems are a type of medical device designed to measure glucose levels in the body over an extended period. These devices are typically implanted under the skin and can provide real-time glucose data to help individuals with diabetes manage their condition more effectively.
Innovation and Patents
Several companies are actively involved in the development of implantable CGM solutions, with numerous patents filed in recent years. For example, Medtronic holds a patent for an implantable CGM system that uses a sensor to measure glucose levels in the interstitial fluid (US Patent 10,456,189) [1]. Similarly, Dexcom has developed an implantable CGM system that uses a small sensor to measure glucose levels in the subcutaneous tissue (US Patent 10,639,714) [2].
Manufacturers and Product Lines
Several manufacturers are currently producing implantable CGM systems, including:
- Medtronic: Offers the Medtronic Guardian Connect system, which includes a small sensor that is implanted under the skin and a transmitter that sends glucose data to a mobile app.
- Dexcom: Offers the Dexcom G6 system, which includes a small sensor that is implanted under the skin and a transmitter that sends glucose data to a mobile app.
- Senseonics: Offers the Eversense system, which includes a small sensor that is implanted under the skin and a transmitter that sends glucose data to a mobile app.
Product Comparison
A comparison of the effectiveness and technology of different implantable CGM systems is shown in the table below:
| Product | Sensor Life | Accuracy | Size |
|---|---|---|---|
| Medtronic Guardian Connect | up to 7 days | MARD: 10.4% | 1.5 cm x 1.5 cm |
| Dexcom G6 | up to 10 days | MARD: 9.0% | 1.2 cm x 0.5 cm |
| Senseonics Eversense | up to 90 days | MARD: 11.1% | 1.5 cm x 1.5 cm |
Pitfalls, Warnings, and Issues
While implantable CGM systems offer many benefits, there are also potential pitfalls and warnings to be aware of. These include:
- Infection and scarring at the implant site
- Sensor failure or malfunction
- Interference from other medical devices
- Cost and accessibility issues
It is essential to carefully weigh the benefits and risks of implantable CGM systems and to consult with a healthcare professional before making a decision.
