Abstract: A continuous analyte sensor system for monitoring a level of an analyte in a bodily fluid of a user. The system comprises a sensor electronics system and an analyte sensor. The sensor electronics system comprises a transceiver for transmitting outgoing signals including the data relating to the analyte level and for receiving incoming signals. The transceiver comprises an electromagnetic signal generating component having first and second signal feed points. The sensor electronics system operates in a first and/or second communication mode. In the first communication mode, the sensor electronics system supplies first outgoing signals to the first signal feed point.

Abstract: An analyte monitor includes a sensor, a sensor control unit, and a display unit. The sensor has, for example, a substrate, a recessed channel formed in the substrate, and conductive material disposed in the recessed channel to form a working electrode. The sensor control unit typically has a housing adapted for placement on skin and is adapted to receive a portion of an electrochemical sensor. The sensor control unit also includes two or more conductive contacts disposed on the housing and configured for coupling to two or more contact pads on the sensor. A transmitter is disposed in the housing and coupled to the plurality of conductive contacts for transmitting data obtained using the sensor. The display unit has a receiver for receiving data transmitted by the transmitter of the sensor control unit and a display coupled to the receiver for displaying an indication of a level of an analyte.
Abstract: Methods, devices, and systems are provided for correcting lag in measurements of analyte concentration level in interstitial fluid. The invention includes receiving a signal representative of sensor data from an analyte monitoring system related to an analyte level measured over time, computing rates of change of the sensor data for a time period of the sensor data, computing a rate distribution of the rates of change, transforming the rate distribution into a linear arrangement, determining a best-fit line for the transformed rate distribution, computing a slope of the best-fit line; and using the slope of the best-fit line as a representation of a variability of the analyte level to adjust an amount of lag correction applied to the sensor data. Numerous additional features are disclosed.
Abstract: Method and system for providing an integrated analyte monitoring system and on-body patch pump with multiple cannulas and a sensor combination is provided.
Abstract: Embodiments described herein include a data receiving device for an analyte monitoring system. The data receiving device detects a disconnect between the data receiving device and a sensor control device of the analyte monitoring system. The data receiving device sets a duration of a scan window for receiving connection data packets from the sensor control device to a current length and initiates the scan window. In response to determining that a connection between the data receiving device and sensor control device has not been established based on connection data packets received during the scan window, the data receiving device performs iterations of a process to adjust the scan window, involving increasing a duration of the scan window to a new length that is greater than the current length and initiating the scan window based on the duration of the scan window at the new length.

Abstract: A medical device includes an antenna external to a case, package, or encapsulant for the electronic systems of the medical device. In one embodiment, a diabetes infusion pump is enclosed within a metal case, the pump including a processor and a communication module for wireless communications. An antenna is disposed in the delivery tubing of the pump outside the case with an antenna feed interconnecting the external antenna with the internal communication module. In another aspect, a thin film antenna is formed on the outer surface of the case in which a physiological parameter sensor, such as a glucose sensor, is enclosed. Multiple antennas may be used for communications on different frequencies.
