Publication number: 20240138720Abstract: Disclosed are devices for determining an analyte concentration. The devices comprise a sensor configured to generate a signal associated with a concentration of an analyte and an electronics unit operatively connected to the sensor. The electronics unit may be engaged with a housing that may secure the device to a host's skin. In this regard, in one embodiment, the housing may be attached to an adhesive patch that is fastened to the skin of the host.Type: ApplicationFiled: November 21, 2023Publication date: May 2, 2024Applicant: Dexcom, Inc.Inventors: Ted Tang Lee, Andrew Trinin Dennis, Shanger Wang, Jiong Zou

Publication number: 20230139158Abstract: Disclosed are devices for determining an analyte concentration (e.g., glucose). The devices comprise a sensor configured to generate a signal associated with a concentration of an analyte and a sensing membrane located over the sensor. The sensing membrane comprises an enzyme layer, wherein the enzyme layer comprises an enzyme and a polymer comprising polyurethane and/or polyurea segments and one or more zwitterionic repeating units. The enzyme layer protects the enzyme and prevents it from leaching from the sensing membrane into a host or deactivating.Type: ApplicationFiled: December 27, 2022Publication date: May 4, 2023Applicant: DexCom, Inc.Inventors: Jiong Zou, Robert J. Boock, Andrew Trinin Dennis, Ted Tang Lee, Jeff T. Suri, David Sze, Mark A. Tapsak, Huashi Zhang, Shanger Wang

Publication number: 20220214300Abstract: Disclosed are devices for determining an analyte concentration (e.g., glucose). The devices comprise a sensor configured to generate a signal associated with a concentration of an analyte and a sensing membrane located over the sensor. The sensing membrane comprises a biointerface layer which interfaces with a biological fluid containing the analyte to be measured. The biointerface layer can comprises a biointerface polymer, wherein the biointerface polymer comprises polyurethane and/or polyurea segments and one or more zwitterionic repeating units. The sensing membrane can also comprise an enzyme layer, wherein the enzyme layer comprises an enzyme and a polymer comprising polyurethane and/or polyurea segments and one or more zwitterionic repeating units. The sensing membrane can also comprise a diffusion-resistance layer, which can comprise a base polymer having a lowest Tg of greater than ?50 C.Type: ApplicationFiled: December 23, 2021Publication date: July 7, 2022Applicant: DEXCOM, INC.Inventors: Shanger Wang, Robert J.
