Single-unit EEG sensors contain multiple closely spaced dry electrodes that can hook onto skin and associated electronic circuitry such as amplifiers, A/D convertors, wireless transmitters, and a power source such as a battery. The electrodes can be separated by about 20 mm or less, and the associated circuitry can be situated within a volume defined by the multiple electrodes. The single-unit sensors hook onto the skin using a tooth surface so that a rotation of the sensor secures and electrically connects the sensor to the skin.

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.

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.

A nerve probe array has a connector made of a flexible material; and a plurality of probes coupled to the connector, each of the plurality of probe having an electrode formed at a body thereof. The plurality of probes are arranged with intervals in a length direction of the connector, and the connector surrounds an outer circumference of a nerve, and the plurality of probes pierce the outer circumference of the nerve and are inserted into the nerve.

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.

Disclosed is electrical stimulation apparatus and an associated method for delivering therapy to an eye of a patient is disclosed, the apparatus comprising: an implantable device comprising one or more electrodes for delivering therapeutic electrical stimulation to the eye, the implantable device being configured for implanting in a suprachoroidal space between the sclera and choroid layers of the eye. Also disclosed is electroretinography (ERG) apparatus for monitoring an eye of a patient, the apparatus comprising: an implantable device comprising one or more electrodes for monitoring properties of the eye, the implantable device being configured for implanting in a suprachoroidal space between the sclera and choroid layers of the eye. Also disclosed are implantable devices, apparatuses and methods for the eye.

A wireless system comprising a first wireless device and a second wireless device. The first wireless device is configured to operate with less than 15 milliamperes of current. The second wireless device has an internal power source and is configured to transmit one or more radio frequency signals to the first wireless device. The first wireless device is configured to receive the one or more radio frequency signals from the second wireless device. The first wireless device is configured to harvest energy from the one or more radio frequency signals.
