This is a product of the itsﾂ�Enlite sensor, which the company touts as its most sensitive glucose sensor with 31% more accuracy from the previous generation, according to a release. When blood sugar levels trigger an abnormal response from the sensor, an alarm sounds first to alert the user, but if there is no response--if the patient is sleeping or unconscious--then the pump shuts down automatically. The Enlite sensor is designed to detect up to 93% of hypoglycemia episodes, the company says, and can be worn for 6 days at a time.
