A multi-lead multi-electrode system and method of manufacturing the multi-lead multi-electrode system includes a multi-electrode lead that may be used to deploy multiple separable electrodes to different spaced apart contact sites, such as nerve or muscle tissues, for example, that are spatially distributed over a large area.

Methods and devices for implanting an intra-ocular pressure sensor within an eye of a patient are provided herein. Methods include penetrating a conjunctiva and sclera with a distal tip of a fluid-filled syringe and positioning the pressure sensor within a vitreous body of the eye by injecting the sensor device through the distal tip. The sensor device may be stabilized by one or more anchoring members engaged with the sclera so that the pressure sensor of the sensor device remains within the vitreous body. Methods further include advancing a sensor device having a distal penetrating tip through at least a portion of the sclera to position the sensor within the vitreous body and extracting of the sensor devices described herein by proximally retracting the sensor device using an extraction feature of the sensor device.

The present invention is directed to a physiological recording device and, more particularly, to a physiological recording device that can be used without skin preparation or the use of electrolytic gels. The invention is further directed to an encouragement ring which stabilizes and helps situate the physiological recording device on a subject's skin to help provide a better electrical signal, increase surface area, and reduce and minimize noise and artifacts during the process of recording or monitoring a physiological signal. The invention is still further directed to surface features on a surface of the physiological recording device with a size and shape that will not substantially bend or break, which limits the depth of application of the recording device, and/or anchors the recording device during normal application. The invention is even further directed to a method for manufacturing a physiological recording device, and minimizing cost of manufacture.

A sensor device includes a sensor housing defining a channel extending along a channel axis through the housing from a first side of the sensor housing to a second side of the sensor housing opposite the first side, at least one contact electrode extending from the first side of the housing, an electrically-conducting lead attached to the housing in electrical communication with the at least one contact electrode, and a locking mechanism located in the channel permitting one-way axial motion of a thread threaded through the channel from the first side to the second side.

Systems, devices, methods, and kits for monitoring one or more physiologic and/or physical signals from a subject are disclosed. A system including patches and corresponding modules for wirelessly monitoring physiologic and/or physical signals is disclosed. A service system for managing the collection of physiologic data from a customer is disclosed. An isolating patch for providing a barrier between a handheld monitoring device with a plurality of contact pads and a subject is disclosed.

This disclosure relates to wireless electronics designed for use within the oral cavity to measure biological or chemical variables, including pH or analyte concentrations, and transmit the measurements. More particularly, the disclosure relates to a wearable intraoral sensor comprising sensing electronics arranged within a flexible circuit mounted onto a molar band, a wireless transmission unit coupled to the sensing electronics and configured to wirelessly transmit electrical data signals to a receiver outside of the oral cavity, and a power source operably coupled to the sensing electronics and wireless transmission unit. The wearable intraoral sensor can be installed around a tooth and continually measure and wirelessly transmit measurement data for extended periods of time without user action.

Systems and methods for applying and/or receiving electrical, magnetic, magnetoelectric, vibratory, or electromagnetic signals to biological tissues are described. In some embodiments, one or more of a conductive tip and a base may be provided. The tip may include a channel and an outer surface that approximates a portion of a sphere or cone and may be sized to fit within a user's ear. The base may be configured to be coupled to the tip and may include a conductor in electrical contact with the tip such that an electrical signal may pass between the base and the tip.

Systems and methods for applying and/or receiving electrical, magnetic, magnetoelectric, vibratory, or electromagnetic signals to biological tissues are described. In some embodiments, one or more of a body, a conductor, an electrode, and a magnetic element may be provided. The conductor may be configured to be electrically coupled to at least one of a power source and a detector. The electrode may include a surface configured to contact a biological tissue portion and apply and/or receive an electrical signal to and/or from the biological tissue portion. The magnetic may selected from a group consisting of a magnet, a toroid, a conductive coil, a magnetic powder, and a magnetic fluid.

A method for obtaining an electroencephalogram (EEG) of a user is disclosed. A reference sensor is attached to the user by connecting a first component of the reference sensor to a second component of the reference sensor, at least a portion of the first component being sub-dermally implanted on or adjacent to a mastoid process of the user. At least one active sensor is attached to the user. A first signal is detected from the reference sensor simultaneously as a second signal is detected from the at least one active sensor. The EEG is obtained based on the first signal and the second signal.

A method and apparatus, the method comprising: applying a conductive contact to a subject's skin; positioning an electrode relative to the conductive contact to enable an electrical connection between the subject's skin and the electrode wherein the electrical connection enables a bio-parameter of the subject to be detected; and wherein at least one of the conductive contact and the electrode are magnetised so as to enable a magnetic field from the magnetised at least one conductive contact and/or electrode to align the conductive contact and the electrode.
