20080214921 | Attachable Surface Electrode For Laryngeal Electromyography - An electrode for laryngeal electromyography that is adhesively secured to an insert device, endotracheal tube or other similar device. The attachable surface electrode of this invention consists of a flexible substrate having an anterior and a posterior surface specifically for insertion along the human laryngopharynx and adjacent to the cricothyroideus muscles (the vocal cords). One or more electrically conductive structures are mounted on or formed on the anterior surface of the substrate to provide an electric contact with the cricothyroideus muscles. Insulated wires extend from the electrical conductive structures for transmitting electrical pulses to the cricothyroideus muscles. There is an adhesive material on the posterior surface of the flexible substrate for attachment to an endotracheal tube, insert device, postcricoid paddle or other such device of the attachable substrate so that the electrically conductive structures thereon are properly positioned for laryngeal electromyography. | 09-04-2008 |
20090264944 | Nerve Stimulator With Suction Capability - A device for use in a removing fluids and debris from a surgical wound and for location of nerves adjacent to the surgical wound comprises a hollow electrically conductive tube which has a lumen extending from the distal end thereof to the proximal end thereof. Openings are located at the distal end of the tube for suction removal of the fluid and debris. A handle located at the proximal end of the tube is provided for attachment of a second tube which is connected to a vacuum source. Also extending from or located within the handle is attachment means for connecting the conductive tube to an electrical nerve stimulation module. An electrically conductive ball is attached at the distal end of the conductive tube and distal to the openings in the tube. The openings are sized so that at least one dimension thereof is less then the diameter of the lumen to prevent the lumen from becoming clogged with debris having a size greater then the diameter of the lumen which is removed from the surgical wound. | 10-22-2009 |
20110071379 | ELECTRODE FOR PROLONGED MONITORING OF LARYNGEAL ELECTROMYOGRAPHY - Laryngeal surface electrodes are devices designed to hold a conductive surface against the vocal cords in order to pick up small electrical signals from the muscle known as electromyographic signals. Several embodiments of a laryngeal electromyography tube include a conductive electrode surface that is painted, screen printed or otherwise applied directly onto the body of an endotracheal tube, such that the final device has no raised surfaces which can injure the vocal cords. These endotracheal tube with integral laryngeal surface electrodes can be safely used placed for prolonged, continuous monitoring during surgery, after surgery and during intensive care treatment intubation without a need to remove and replace the tube at these various stages of treatment. In one embodiment, one electrode contacts the vocal cords and a second electrode contacts the tongue. | 03-24-2011 |

20140163411 | METHOD OF DETECTING REVERSIBLE NERVE INJURY - A method of monitoring relative nerve health and the presence of neuropraxia is described. The methods utilize the integration of a waveform function of an elicited or monitored nerve response to provide an indication of the strength of a detected signal from a nerve and thus the relative health and integrity of the nerve. In some embodiments motor nerve stimulation innervates muscle and an EMG waveform is obtained in response thereto. The integration under the waveform is expressed and an indexed value indicating a percentage of a certain threshold value. Methods set forth provide a more reliable status of a nerve in real-time and allow action to be taken to reduce neuropraxia or prevent permanent nerve damage. | 06-12-2014 |

20110304546 | ELECTRONIC BRAILLE TYPING INTERFACE - A user interface system for entry of Braille input to electronic devices comprises a module with a single set of six tactile keys arranged in a 6 dot Braille configuration. The user interface system is configured to recognize data entered therein by user contact with one or more of the tactile keys as Braille input and to transmit said Braille input to an electronic device for display or further transmission. The interface further includes function keys which allow the user to manipulate, modify, or otherwise control the data entered and how the data is transmitted. | 12-15-2011 |
20120130269 | INTEGRATED NERVE STIMULATION AND SKIN MARKING DEVICE AND METHODS OF USING SAME - A nerve identification device is shown and described. The device includes both a nerve stimulating electrode and a skin marking device. In certain applications, a user contacts the patient's skin with the nerve stimulating electrode to deliver nerve stimulation energy that evokes an electrical response from proximally located motor nerves. When nerves are detected, the user applies skin ink via the device to the user's skin to identify the location where nerves were found for subsequent use in a variety of therapeutic procedures such as surgical procedures, pain treatment procedures, degenerative nerve destruction procedures, and the treatment of obstructive sleep apnea. | 05-24-2012 |
20120150063 | HANDHELD EMG STIMULATOR DEVICE WITH ADJUSTABLE SHAFT LENGTH - A nerve stimulating device with an adjustable length is shown and described. The device includes a handle and an elongated shaft with a stimulating electrode. The stimulating electrode can be selectively positioned to a plurality of distances relative to the handle. The device allows nerves in nerve regions at multiple positions relative to the surface of the patient's body to be stimulated with a single device. | 06-14-2012 |
