Patents by Inventor Michael D. Ehninger

Michael D. Ehninger has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10478250
    Abstract: An electrosurgical return electrode configured for operable association with a transponder detection unit. The return electrode includes a conductive element having an aperture array configured to allow passage of a magnetic, electric, or electromagnetic interrogation signal from the transponder detection unit through the conductive element and through the return electrode. The return electrode is positionable over a transponder detection unit such that the return electrode may be placed upon the transponder detection unit and a patient may be positioned upon the return electrode. The return electrode enables the detection of a transponder located on, within, and/or near the patient without the need for repositioning the patient relative to the return electrode and without the need for positioning an ancillary transponder reader or transmitter above the patient.

  • Publication number: 20180368908
    Abstract: A self-limiting electrosurgical return electrode for use with electrosurgical procedures is disclosed. The return electrode includes a conductive element and pads disposed on opposing sides of the conductive element. The conductive element, optionally in combination with the pads, is configured to limit the density of electrical current that passes from a patient to the return electrode. The conductive element and the pads can cooperate to define two separate working surfaces on opposing sides of the return electrode. The return electrode can also be safely used with patients of substantially any size and without requiring adjustments to the power settings of an electrosurgical generator.

  • Publication number: 20170365948
    Abstract: Cable connection systems allow for an electrosurgical return electrode to be simultaneously connected to multiple ESUs. The cable connection systems can include individual return cables for simultaneous connection to each of the ESUs. The cable connection system can also include a junction that joins, connects, or associates the return cables in a manner that allows for the multiple ESU cables to be electrically connected to the return electrode at a single connection point on the return electrode.
