Abstract: Disclosed are various aspects for a squeeze and stick subdermal needle electrode. A squeeze and stick subdermal needle electrode may comprise (a) an electrode housing with (i) an inner portion with an opening to receive a subdermal needle on a proximal side, and a lead wire on a distal side, wherein the subdermal needle and the lead wire are mated together to transfer electrical signals; and (ii) an outer portion for protecting the inner portion, the outer portion capable of compressing onto the inner portion, wherein when compressing drives the subdermal needle toward a patient. Further, methods of compressing the outer portion to drive the inner portion of the subdermal needle electrode into a subdermal region of the patient are disclosed.

Abstract: Disclosed are various embodiments for a butterfly hinge electrode and uses thereof. A butterfly hinge electrode may have a first and second wing positioned adjacent to one another and connected through a coupling mechanism. The butterfly hinge electrode may have a first and second electrode assembly, the first electrode assembly positioned on the first wing and the second electrode assembly positioned on the second wing. The butterfly hinge electrode may further comprise a compression assembly. Further, the butterfly hinge electrode may be inserted into a subdermal layer of a patient for neurological monitoring through the use of the first and second electrode assemblies on the first and second wings.

Abstract: An electrode system for neurological monitoring is disclosed, including a housing with a recess dimensioned to hold an electrode. A conductive gel is applied to said electrode to limit direct contact by said electrode to a patient's skin. The recess defines a wall in said housing that engages the patient's skin. A thin bead of adhesive applied to the top surface of the wall secures the housing, and therefore the electrode, to the patient. Finer electrical conductor wires in a more flexible insulator lead from the electrode to a connector that fits into a neurological monitoring amplifier. The electrode system further comprising a template structure for precisely locating and adjusting to a patient's dimensions.

Abstract: A needle electrode fixation device is configured to secure a transdermal needle electrode to a patient. The device includes a base having a body that defines a first portion and a second portion. The first and second portions are rotatable relative to each other. The first portion defines a channel configured to fit a portion of the transdermal needle electrode. The second portion defines a recess configured to fit a tip of the needle electrode. The device further includes an adhesive layer configured to affix the base to the patient. The device is at least partially transparent or translucent and includes one or more viewing windows to provide visibility of individual components, such as the needle electrode.

Abstract: In various example embodiments disclosed herein, a Dynamic Security Architecture Environment (DSAE) security architecture is provided in an externally connectable endpoint device (the security device), which can be connected to an existing host endpoint device, such as a computer, laptop, tablet, phone, vehicle, medical device, Industrial Control System (ICS), or other electronic or Internet connected device. The example embodiments can implement the DSAE security architecture in the security device that connects to a host endpoint device to make the host endpoint device more secure by enabling the security device to combat cyber attacks targeted toward the host device. The example embodiments described herein also provide details for creating a security device that leverages the DSAE architecture, wherein the security device is configured to connect via a wired or wireless medium for data communication with a host endpoint device to make the host device more secure.

Abstract: A multi-electrode applicator includes a carrier with recesses formed in pre-selected locations on one side. Each recess carries an electrode, and optionally both an applicator and an electrode, so that, when that side of the carrier is applied to a surface, the electrodes engage the surface in their pre-selected locations. An adhesive is applied to the underside of the carrier to cause the carrier to stick to the skin surface. A release paper may be applied over the adhesive so that, when the paper is removed, the adhesive is exposed and the carrier can then be stuck to the skin. The carrier may be flat or curved, and the electrodes may be self-embedding electrodes, a stimulating- or recording-type electrode, or a ground electrode-reference electrode pair. Electrical conductor connects the electrode to a monitor directly or via a multi-pin connector.
