Publication number: 20240109229Abstract: Apparatuses and methods for attaching a hydrogel film to a product. The hydrogel film may be produced by injecting a monomer solution into a mold, polymerizing the monomer solution in the mold to produce a hydrogel sheet, and cutting the hydrogel sheet to produce one or more hydrogel films. The process may include attaching a hydrogel film of the one or more hydrogel films to a product. Attaching the hydrogel sheet to the product may include applying an adhesive onto the product, placing a first edge of the hydrogel film in the adhesive on the product, and placing a second edge of the hydrogel film in the adhesive on the product.Type: ApplicationFiled: October 2, 2023Publication date: April 4, 2024Applicant: Senseonics, IncorporatedInventors: Philip Huffstetler, Sanat Mohanty, Giacomo Fornasini, Robert Atwood

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.

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.
