What changed

The USPTO granted Insulet Corporation Patent US12592306B2 on March 31, 2026, covering devices and methods for initializing drug delivery devices using measured analyte sensor information. The patent enables a new drug delivery device exchanged for a previous device to operate using analyte-based drug delivery control immediately during initialization instead of waiting for a warm-up period. The system receives present analyte measurements and historical backfill values from the sensor, calculates drug dosage, and delivers it without delay. Application 17730839 was filed April 27, 2022, and the patent contains 16 claims.

This patent grant does not create any compliance obligations, reporting requirements, or deadlines for medical device or pharmaceutical companies. Medical device manufacturers developing insulin pumps, continuous glucose monitors, or similar drug delivery systems should assess whether their technology may fall within the scope of these claims. Companies may wish to evaluate potential licensing needs or design-around options to mitigate infringement risk.

Abstract

Disclosed are processes and techniques implementable by a drug delivery system to maintain optimal drug delivery for a patient according to a treatment plan. The disclosed techniques enable a new drug delivery device that is exchanged for a previous drug delivery device to operate using analyte-based drug delivery control immediately during initialization instead of having to wait for a warm-up period. For example, a drug delivery device may include a processor and a memory storing instructions that, when executed by the processor, operate the drug delivery device to receive a present analyte measurement value from an analyte sensor during an initialization of the drug delivery device, receive backfill values measured by the analyte sensor prior to the initialization, calculate a dosage of a drug using the present analyte measurement value and the backfill values, and deliver the dosage of the drug. Other embodiments are described.
