Abstract: Disclosed herein are apparatus and techniques for applying a device to a subject. Such apparatus and techniques may provide feedback to an operator and/or regulate the force used to apply the device, yielding an improved result. Particularly useful embodiments include apparatus and techniques for applying a medical device, such as a skin surface electrode or microneedle array, to a patient's tissue.

Abstract: Apparatus and techniques are provided for interfacing a device with a surface. The apparatus and techniques provide gel encapsulation and isolation mechanisms to extend the shelf-life of the preparation devices, allow for the use of more effective materials, and improve the quality of the contact between a device and an application surface. Particular embodiments of these apparatus and techniques suitable for use in medical contexts are also provided.

Abstract: Embodiments of the present disclosure relate to sensor designs or shapes configured to facilitate placement of sensor electrodes and, thus, proper positioning of the sensors on patients. According to certain embodiments, a sensor may include a substrate that includes multiple electrodes, where a first electrode is configured to be placed on a patient's temple and a second electrode is configured to be placed on a patient's forehead directly above a patient's eyebrow. The sensor may include a particular shape and a fixed distance between the first and second electrodes to facilitate proper angling and positioning of the first and second electrodes as well as the other electrodes (e.g., third and fourth electrodes). Other embodiments may include a method for positioning the sensor on the patient, including a monitor with help screens.

Abstract: The present disclosure describes systems and methods for creating sharp features within a mold. For example, three or more mold plates may be provided to create a single mold assembly. Each mold plate includes one or more mold cavities, each having one or more surfaces. The provided mold plates may be assembled to form the mold assembly having a combined mold cavity between adjacent mold cavities of the mold plates. Although none of the individual mold cavities of the mold plates include sharp features, when the mold assembly is assembled, a combined mold cavity will include sharp transitions (e.g., angles of less than 180 degrees, right angles, angles of less than 90 degrees, and so forth) between adjacent surfaces of the mold cavities. In certain embodiments, sets of mold plates may be re-aligned to create varying mold cavity geometries. In addition, in certain embodiments, a mold pin may be inserted into an inner volume of a mold plate to both create additional sharp transitions between adjacent surfaces.

Abstract: A disposable electrode assembly for contacting a patient and for receiving electrical signals from at least one remotely located electrode, the remotely located electrode having leads. The electrode assembly has a thin, flexible, leg plate with a bottom surface contacting the patient without adhesive. At least two triangular-shaped springs are carried by the leg plate for electrically and mechanically connecting the leads from the remotely located electrode to the leg plate. At least two latches, each adapted to snap over one of the triangular-shaped springs, provide an audio indication of flap closure and keep a flap closed over each of the triangular-shaped springs. A reference electrode electrically contacts the patient through a skin-contacting surface when the electrode assembly is secured to the patient. The reference electrode is electrically coupled to, but mechanically decoupled from, the leg plate. Separate, insulated wires electrically engage the springs and the reference electrode.

Abstract: A low profile connector, as for an electrode, is disclosed. The connector of the invention includes an electrically conductive connector body and electrical connector means to separate electronics. The connector body has a channel or groove which communicates with one side of the connector body and its bottom. The channel leads to a "stop" position located substantially the central portion of said body. Viewed from the bottom of the connector body, the channel is interiorly concave so as to cooperatively, preferably rotatively and restrictively receive and hold an upstanding portion of an electrode, such as an electrode eyelet. In a preferred aspect, the present invention is an electrical assembly which includes the connector body and a biomedical electrode, such as a TENS electrode.
