Application: Devices and methods for measuring a concentration of a target analyte in a biological fluid in vivo (Patent ID: US20240074682A1)
The patent filed by DexCom Inc. describes devices and methods for continuously measuring the concentration of a target analyte in a biological fluid in vivo. The device includes an indwelling sensor with a substrate, first and second electrodes, and an ion-selective membrane containing an ionophore to transport the target analyte to the first electrode. The sensor electronics generate a signal based on the potential difference between the electrodes when the ionophore transports the target analyte.
The ion-selective membrane can be made of various materials such as fluorosilicone rubber or polyurethane, while the electrodes can be metals, metal alloys, or conductive polymers like PEDOT or PANI. The ionophore used includes compounds like valinomycin or nonactin. The device may also include a solid contact layer with materials like carbon ink or doped semiconductors. Additionally, the device can measure various target analytes such as sodium, potassium, glucose, or urea. The sensor electronics can be configured to measure the electromotive force with a dynamically configurable frequency and can deconvolve contributions from electrophysiological signals and analyte concentrations. The method for measuring the target analyte involves using the indwelling sensor and generating a signal based on the potential difference between the electrodes when the ionophore transports the target ion.
