Publication number: 20100063373Abstract: Disclosed herein are systems and methods for calibrating a continuous analyte sensor, such as a continuous glucose sensor. One such system utilizes one or more electrodes to measure an additional analyte. Such measurements may provide a baseline or sensitivity measurement for use in calibrating the sensor. Furthermore, baseline and/or sensitivity measurements may be used to trigger events such as digital filtering of data or suspending display of data.Type: ApplicationFiled: November 16, 2009Publication date: March 11, 2010Applicant: DexCom, Inc.Inventors: Apurv Ullas Kamath, Peter C.

Publication number: 20100045465Abstract: Systems and methods for dynamically and intelligently estimating analyte data from a continuous analyte sensor, including receiving a data stream, selecting one of a plurality of algorithms, and employing the selected algorithm to estimate analyte values. Additional data processing includes evaluating the selected estimative algorithms, analyzing a variation of the estimated analyte values based on statistical, clinical, or physiological parameters, comparing the estimated analyte values with corresponding measure analyte values, and providing output to a user. Estimation can be used to compensate for time lag, match sensor data with corresponding reference data, warn of upcoming clinical risk, replace erroneous sensor data signals, and provide more timely analyte information encourage proactive behavior and preempt clinical risk.Type: ApplicationFiled: October 12, 2009Publication date: February 25, 2010Applicant: DexCom Inc.Inventors: James H.

Publication number: 20100049024Abstract: Devices suitable for implantation in a body of a host and systems and methods for their manufacture are provided. The implantable devices include a composite material formed at least from a matrix material and hollow gas-filled beads. In preferred embodiments, the composite material includes a polymeric matrix mixed with hollow air-filled glass beads, which are mixed and cured to form at least a portion of the body of the implantable device. Implantable devices including this composite material have decreased weight and/or overall density as compared to implantable devices without the beads incorporated therein, which is believed to improve the acceptance and function of the implantable device in vivo. Additionally, implantable devices concerned with transmitting and receiving via RF are believed to achieve improved RF performance due to a reduced dielectric constant provided by the incorporation of beads within the composite material.Type: ApplicationFiled: October 30, 2009Publication date: February 25, 2010Applicant: DexCom, Inc.Inventors: Sean Saint, Mark Brister

Publication number: 20100041971Abstract: An implantable analyte sensor including a sensing region for measuring the analyte and a non-sensing region for immobilizing the sensor body in the host. The sensor is implanted in a precisely dimensioned pocket to stabilize the analyte sensor in vivo and enable measurement of the concentration of the analyte in the host before and after formation of a foreign body capsule around the sensor. The sensor further provides a transmitter for RF transmission through the sensor body, electronic circuitry, and a power source optimized for long-term use in the miniaturized sensor body.Type: ApplicationFiled: October 29, 2009Publication date: February 18, 2010Applicant: DexCom, Inc.Inventors: Paul V.

Publication number: 20100036225Abstract: Systems and methods for minimizing or eliminating transient non-glucose related signal noise due to non-glucose rate limiting phenomenon such as ischemia, pH changes, temperatures changes, and the like. The system monitors a data stream from a glucose sensor and detects signal artifacts that have higher amplitude than electronic or diffusion-related system noise. The system replaces some or the entire data stream continually or intermittently including signal estimation methods that particularly address transient signal artifacts. The system is also capable of detecting the severity of the signal artifacts and selectively applying one or more signal estimation algorithm factors responsive to the severity of the signal artifacts, which includes selectively applying distinct sets of parameters to a signal estimation algorithm or selectively applying distinct signal estimation algorithms.Type: ApplicationFiled: October 14, 2009Publication date: February 11, 2010Applicant: DexCom, Inc.Inventors: Paul V.
