This disclosure sets forth various systems and methods for deploying anchored medical devices within a human or animal. The medical devices may deliver payloads, such as various sensors, electrodes, transmitters, cameras, electrical or other interventional devices, drugs or therapeutics. The devices may have one or more anchors, which attach the device to an anatomy of interest. This allows for methods and processes to be performed over periods of time, such as extended delivery of a therapy or real time sensing of characteristics inside a body, which the device remains within a given location.

A biosensor assembly that measures multiple physical parameters is disclosed. The biosensor assembly includes a first implantable probe and a first skin contacting electrode. Wherein a first physiological parameter is measured between the first implantable probe and the first skin contactable electrode.

Provided are transdermal microneedle-based devices for sensing the presence and concentration of analytes such as electrolytes, biomarkers, drugs, and proteins in interstitial fluid. Also provided are methods and systems to transmit the data obtained by wired or wireless connection to a receiver and to relay the data to the user or a clinician.

Fault detection and diagnostics for a microneedle array based continuous analyte monitoring device are provided. The electrochemical sensors, including the electrodes of the analyte monitoring device configured for measuring one or more target analytes, may experience various faults during use of the analyte monitoring device. By modeling the sensors as an electrical network, measurements of the electrical network may be correlated with operational parameters of the sensor. The voltage at the counter electrode provides an indication of the resistance or impedance between the working electrode and the counter electrode and is used to identify the occurrence of faults occurring at the continuous analyte monitoring device.

Disclosed is a system and method for performing measurements on a biological subject, and in one particular example, to performing measurements of analytes in a biological subject by breaching a functional barrier of the subject using microstructures, wherein the one or more microstructures include an aptamer for binding one or more analytes.

Microneedle (100, 200, 300, 720) comprising an elongated body (110, 210, 310) extending along a longitudinal axis from a top end to a bottom end on a substrate (300, 710), where the elongated body comprises an upper portion (120, 220, 320) and a lower portion (130, 230, 330). The lower portion (130, 230, 330) comprises an internal capillary bore hole (260, 730) extending into the substrate (300, 710). The upper portion (120, 220, 320) of the elongated body (110, 210, 310) has a semi-enclosed internal void space (140, 240) formed by at least three body sides whereof two body sides join at a sharp edge and a third body side is provided with an opening slit (150, 250, 350) extending from the lower portion (130, 230, 330) of the elongated body (110, 210, 310) to the upper end of the third body side. The top end of the elongated body (110, 210, 310) is configured as a bevel to create a sharp tip at the top of said edge, said bevel extending to the third body side. The semi-enclosed internal void space (140, 240) of the upper portion opening to the internal capillary bore hole of the bottom end of the elongated body (110, 210, 310), and the bottom end of the elongated body is connected to the substrate (300, 710).

Disclosed is a wearable microneedle sensor platform for minimally-invasive, real-time monitoring of key biomarkers. In some aspects, a device includes a wearable epidermal sensor comprising an array of hollowed needles, each hollowed needle having a protruded needle structure including multiple layers forming a hollow interior, at least one hollowed needle including a working electrode to interact with one or more chemical or biological substances that come in contact with the protruded needle structure, at least one hollowed needle including a counter electrode to measure an electrical potential difference with the working electrode; and a wireless transmitter in communication with the sensor to generate output signals based on the electrical potential difference with the working electrode. The output signal represents β-hydroxybutyrate as a biomarker of ketone bodies.

Wearable blood pressure biosensors, systems, and methods for short-term blood pressure predictions are disclosed herein. In some embodiments, a blood pressure prediction system is configured to provide short-term predictions of average blood pressures for future time period(s) or horizon(s) (e.g., for a coming week). The system can include models trained to predict future systolic values, diastolic blood pressure values, and/or trends. The models can be trained on data related to personalized body, health, and/or physical characteristics of the user, e.g., the current or previous blood pressure, amount of sleep, heart rate, blood glucose (BG), activity, weight, etc. In some embodiments, the models can also determine whether the blood pressure of the user will change or remain relatively constant over a period/range of time.

An electrophysiological monitoring system includes an electrophysiology amplifier chip configured to couple to a plurality of electrophysiological electrodes and to measure electrophysiological signals. The system also includes a computing device configured to receive and to process the electrophysiological signals. The system further includes an interface device coupled to the electrophysiological amplifier chip and the computing device, the interface device configured to convert communication signals between the computing device and the electrophysiology amplifier chip.
