Which system received initial FDA approval in 1999 for continuous glucose monitoring?
Answer
Medisense Continuous Glucose Monitoring System
The Medisense Continuous Glucose Monitoring System is specifically noted as a significant early contributor that achieved initial FDA approval in 1999, marking a critical regulatory milestone for continuous monitoring technology. Although this early system exhibited transitional characteristics, such as requiring frequent calibration using traditional fingerstick meters, its approval paved the way for future wearable devices. These initial systems consisted of an inserted sensor filament that wirelessly connected to a separate receiver worn by the user, representing a major step away from purely spot-checking methods.
