Patent number: 11826143Abstract: A sensor (e.g., an optical sensor) that may be implanted within a living animal (e.g., a human) and may be used to measure an analyte (e.g., glucose or oxygen) in a medium (e.g., interstitial fluid, blood, or intraperitoneal fluid) within the animal. The sensor may include a sensor housing, an analyte indicator covering at least a portion of the sensor housing, and a multiple metal protective system including multiple metals incorporated in and/or in close proximity to a surface of the analyte indicator that reduce deterioration of the analyte indicator.Type: GrantFiled: December 5, 2019Date of Patent: November 28, 2023Assignee: Senseonics, IncorporatedInventors: Mark Mortellaro, Venkata Velvadapu, Tina Hyunjung Kim

Publication number: 20230103609Abstract: A sensor, system, and method for detecting and correcting for changes to an analyte indicator of an analyte sensor. The analyte indicator may be configured to exhibit a first detectable property that varies in accordance with an analyte concentration and an extent to which the analyte indicator has degraded. The analyte sensor may also include a degradation indicator configured to exhibit a second detectable property that varies in accordance with an extent to which the degradation indicator has degraded. The analyte sensor may generate (i) an analyte measurement based on the first detectable property exhibited by the analyte indicator and (ii) a degradation measurement based on the second detectable property exhibited by the degradation indicator. The analyte sensor may be part of a system that also includes a transceiver. The transceiver may use the analyte and degradation measurements to calculate an analyte level.Type: ApplicationFiled: December 2, 2022Publication date: April 6, 2023Applicant: Senseonics, IncorporatedInventors: Andrew Dehennis, Mark Mortellaro, Abhi Chavan, Venkata Velvadapu, Philip Huffstetler, Tina HyunJung Kim, James Masciotti
