Publication number: 20230034606Abstract: Methods, systems, and computer readable media are disclosed for estimating an amount of an analyte in blood of a subject. In an example, a method includes obtaining a noise filtered current by noise filtering a current received from an analyte sensor placed interstitially in tissue of the subject, estimating one or more blood analyte calibration parameters based on the noise filtered current, obtaining a second set of one or more interstitial analyte calibration parameters based at least in part on the one or more blood analyte calibration parameters, and estimating the amount of the analyte in the blood of the subject based on the noise filtered current and the one or more interstitial analyte calibration parameters. In this way, an analyte sensor that is placed interstitially may readily be calibrated to report accurate blood analyte values.Type: ApplicationFiled: September 29, 2022Publication date: February 2, 2023Applicant: WaveForm Technologies, Inc.Inventors: Abhinoy Kumar SINGH, Mihailo V.

Publication number: 20230027609Abstract: Embodiments provide for methods, systems, apparatus and computer readable media for calibrating an analyte sensor upon insertion into tissue of a subject based at least in part on parameters obtained from another analyte sensor already calibrated and previously inserted into the tissue of the subject. As an example, a method may include predicting a background current associated with the newly inserted sensor, subtracting the background current from a current measured by the newly inserted sensor, and converting the subtracted current to a glucose value, the converting based at least in part on the parameters obtained from the previously inserted analyte sensor. In this way, the newly inserted sensor may be calibrated without relying on actual blood-based analyte measurements, and accuracy and sensitivity of the newly inserted sensor may be improved.Type: ApplicationFiled: September 21, 2022Publication date: January 26, 2023Applicant: WaveForm Technologies, Inc.Inventors: Mihailo V.

Publication number: 20210228114Abstract: Systems and methods for operating continuous analyte monitoring (CAM) device are provided. In one example, a method comprises converting a first analyte data stream into analyte values reflective of a biological concentration of the analyte, obtaining one or more additional data streams from one or more adjunctive sensors, inferring based on the first data stream and the one or more additional data streams that conversion of the first data stream into analyte values is predicted to be inaccurate, and taking mitigating action to avoid inaccurate analyte values from being reported to a user. In this way, corrective measures can be taken to improve overall CAM device operation, quality of data provided via a CAM device may be enhanced, and user health and safety profile associated with the continuous analyte monitoring device may be improved.Type: ApplicationFiled: January 22, 2021Publication date: July 29, 2021Applicant: WaveForm Technologies, Inc.Inventors: Mihailo V.

Publication number: 20200000408Abstract: A device and method for delivering a device such as a sensor or fluid transport structure or a fluid transport structure sensor combination into, for example, mammalian skin. Such a device allows a sensor to penetrate mammalian skin without the use of an introducer device such as a needle. A device in accordance with embodiments of the present disclosure includes a housing for attachment to mammalian skin including an exit port for receiving the distal end of a biosensor and an injection activation device including a mechanism for forcing the sensing device from a first position within the housing, through the exit port to a second position, with sufficiently high velocity to partially penetrate the mammalian skin.Type: ApplicationFiled: September 4, 2019Publication date: January 2, 2020Applicant: WAVEFORM TECHNOLOGIES, INC.Inventors: Mark NEINAST, Robert BRUCE, W.

Publication number: 20190313974Abstract: Embodiments provide a sensor insertion tool (SIT) that provides a motive force for insertion of an analyte sensor into/through skin. A SIT may be releasably locked to one or more components of a sensor insertion system, such that components of the sensor insertion system remain securely coupled during sensor insertion. A SIT may include a release member that unlocks or uncouples the SIT and the other components after sensor insertion. In various embodiments, a SIT may be a component of a sensor insertion system configured for assembly by an end user, a health care professional, and/or a caretaker prior to sensor insertion, and may act in cooperation with other sensor insertion system components. Additional components and methods of assembly and use are also provided herein.Type: ApplicationFiled: June 28, 2019Publication date: October 17, 2019Applicant: WAVEFORM TECHNOLOGIES, INC.Inventors: Robert BRUCE, David KREITLOW, Isaac FEDERIUK, Ryan POLCIN, Dennis SLOMSKI, Eric WARD, Mihai RESCH

Patent number: 10383555Abstract: Embodiments herein provide detection of contamination at one or more contacts of a sensor system. The sensor system includes a sensor assembly and an electronics assembly communicatively coupled together by one or more contacts. The sensor assembly passes a sensor signal to the electronics assembly for further processing. The electronics assembly includes a detection contact for detecting contamination on or near one or more contacts of the sensor assembly and/or the electronics assembly. A switch selectively couples the detection contact to a bias voltage during a measurement mode and to a reference voltage during a detection mode, the reference voltage being different from the bias voltage. A method of contamination detection includes switching the electronics assembly between the measurement mode and the detection mode, and monitoring for a change in the output signal received by the electronics assembly.Type: GrantFiled: February 23, 2018Date of Patent: August 20, 2019Assignee: WAVEFORM TECHNOLOGIES, INC.Inventors: Igor Gofman, Mu Wu
