Publication number: 20240041366Abstract: A sensor, system, and method for detecting and correcting for an effect on an analyte indicator of an analyte sensor. The analyte indicator may have a first detectable property that varies in accordance with an analyte concentration and an effect on (e.g., degradation of) the analyte indicator. The analyte sensor may also include an interferent indicator having a second detectable property (e.g., absorption) that varies in accordance the effect on the analyte indicator. The analyte sensor may generate (i) an analyte measurement based on the first detectable property of the analyte indicator and (ii) an interferent measurement based on the second detectable property of the interferent indicator. The analyte sensor may be part of a system that also includes a transceiver. The transceiver may use the analyte and interferent measurements to calculate an analyte level.Type: ApplicationFiled: October 6, 2023Publication date: February 8, 2024Applicant: Senseonics, IncorporatedInventors: Andrew DeHennis, Mark Mortellaro, Abhi Chavan, Venkata Velvadapu, Philip Huffstetler, James Masciotti, Patricia Sanchez

Patent number: 11109779Abstract: A sensor that may be used to detect the presence, amount, and/or concentration of an analyte in a medium within an animal. The sensor may include a sensor housing, an indicator element embedded within and/or covering at least a portion of the sensor housing, and a membrane over the indicator element. The sensor may include one or more of a first coating on an inner surface of the membrane, a second coating on an outer surface of the membrane, and a layer on the outside of the indicator element. One or more of the first coating, second coating, and layer may reduce deterioration of the indicator element by catalyzing degradation of reactive oxygen species (ROS). The one or more coatings on the membrane may increase the light blocking capability of the membrane, which may improve the accuracy of the sensor.Type: GrantFiled: June 15, 2018Date of Patent: September 7, 2021Assignee: Senseonics, IncorporatedInventors: Jeremy Emken, Philip Huffstetler, Todd Whitehurst, Masika Hinds, Mark Mortellaro, Abhi Chavan, Bryan Hays
