Abstract: An insertion device configured to implant a first medical device and a second medical device in a user. The first medical device may be a fluid delivery cannula configured to deliver a fluid (e.g., insulin) to the user. The second medical device may be an analyte sensor (e.g., a glucose sensor) configured to detect a physiological characteristic of the user (e.g., a glucose level). The insertion device may be configured to be worn by the user. The insertion device includes a first linkage assembly configured to extend and retract a first insertion needle to implant the first medical device and a second linkage assembly configured to extend and retract a second insertion needle to implant the second medical device. The insertion device includes a user input device configured to cause the insertion device to initiate the implantation when activated by the user.

Abstract: In some examples, a system for monitoring glucose includes processing circuitry and a glucose monitor comprising one or more monitor electrodes and one or more working electrodes, wherein a first chemistry stack is disposed on at least one of the monitor electrode(s) and a second chemistry stack is disposed on at least one of the working electrode(s). The processing circuitry may be configured to measure one or more calibration values of an operating parameter of the monitor electrode(s), retrieve one or more pre-calibration values of the operating parameter of the monitor electrode(s), wherein the pre-calibration value(s) were measured before the calibration value, determine one or more delta values using the calibration value(s) and the pre-calibration value(s), and calibrate glucose values sensed by the working electrode(s) using the delta value(s).

Abstract: A medicine injection pen includes a body, a drive member, a cartridge housing, and a medicine cartridge retained within the cartridge housing. The drive member is configured to move relative to the body and the medicine cartridge defines an interior volume configured to retain a liquid medicine. The drive member is configured to translate a piston within the interior volume toward a dispensing end of the medicine cartridge to dispense at least some of the liquid medicine. The medicine cartridge also includes an insertion port configured to receive a medicine dispensing element therethrough for dispensing a liquid medicine into the interior volume to replace at least some of the liquid medicine dispensed through the dispensing end. Dispensing of the liquid medicine into the interior volume of the medicine cartridge applies a fluid pressure to the piston to translate the piston away from the dispensing end of the medicine cartridge.

Abstract: Methods for operating sensing devices, methods for correcting sensor glucose measurement signals, methods for detecting interferents in body fluid, and analyte monitoring apparatuses are provided. An exemplary method for operating a sensing device includes storing a library of changes in electrochemical impedance spectroscopy (EIS) signals correlated to known concentrations of the interferent within bodies of study subjects, wherein the library is accessible to a controller. The method also includes monitoring EIS signals of the user with the controller. Further, the method includes matching, with the controller, a change in an EIS signal of the user with a change in a selected EIS signal from the library. The method determines a concentration of an interferent within the body of a user based on the selected EIS signal from the library.

Abstract: A disposable medical introduction system including a medical device and a disposable inserter. The disposable inserter includes a carrier to receive the medical device. The carrier includes at least one annular projection. The disposable inserter includes a retractor received within the at least one annular projection and movable relative to the at least one annular projection. The retractor has at least one retaining arm. The disposable inserter includes a needle cartridge coupled to the retractor that includes an insertion needle. The at least one retaining arm cooperates with the needle cartridge to maintain the insertion needle in a first, extended state. A movement of the retractor relative to the at least one annular projection releases the at least one retaining arm to move the insertion needle from the first, extended state to a second, retracted state.
