  • Publication number: 20240008778
    Abstract: An on-body insertion system is described. The on-body system includes a sensor in a first position being substantially parallel to an insertion surface. Activation of an actuator transitions the sensor to a second position. Wherein the transition imparts movement to the sensor that is substantially parallel to the insertion surface and the second position results in the sensing area being beneath the insertion surface.

  • Publication number: 20230360799
    Abstract: A method for retrospective calibration of a glucose sensor uses stored values of measured working electrode current (Isig) to calculate a final sensor glucose (SG) value retrospectively. The Isig values may be preprocessed, discrete wavelet decomposition applied. At least one machine learning model, such as, e.g., Genetic Programing (GP) and Regression Decision Tree (DT), may be used to calculate SG values based on the Isig values and the discrete wavelet decomposition. Other inputs may include, e.g., counter electrode voltage (Vcntr) and Electrochemical Impedance Spectroscopy (EIS) data. A plurality of machine learning models may be used to generate respective SG values, which are then fused to generate a fused SG. Fused SG values may be filtered to smooth the data, and blanked if necessary.

  • Patent number: 11701034
    Abstract: An introducer is provided for introducing a sensor into the body of a patient. The introducer connects to a sensor hub. When the sensor hub and introducer are connected, the introducer needle is exposed. When the sensor hub and introducer are disconnected, a needle cover and the needle move with respect to each other so that the needle cover substantially covers the needle, protecting a user from being injured by the needle.

  • Publication number: 20230106459
    Abstract: In one embodiment, an infusion set and sensor assembly delivered within a subject is disclosed. The assembly includes a cannula that is terminated at a cannula opening. The assembly further includes a sharp that is at least partially within the hollow of the cannula. A sensor having a proximal end and a distal end is also included in the assembly. The proximal end of the sensor is held in a fixed location while the distal end is retained with a portion of the cannula. The sensor further includes sensor slack, wherein transitioning the sharp from a first position to a second position simultaneously inserts the cannula and sensor to a desired insertion depth within a subject via a single point of insertion.
