  • METHODS AND SYSTEMS RELATED TO ELECTROSURGICAL WANDS
    Publication number: 20170290619
    Abstract: Electrosurgical wands. At least some of the illustrative embodiments are electrosurgical wands having features that reduce contact of tissue with an active electrode of a wand, decrease the likelihood of clogging, and/or increase the visibility within surgical field. For example, wands in accordance with at least some embodiments may comprise standoffs, either along the outer perimeter of the active electrode, or through the main aperture in the active electrode, to reduce tissue contact. Wands in accordance with at least some embodiments may implement slots on the active electrodes to increase bubble aspiration to help keep the visual field at the surgical site clear. Wands in accordance with at least some embodiments may implement aspiration flow pathways within the wand that increase in cross-sectional area to reduce the likelihood of clogging.

  • Positioning guidance for increasing reliability of near-field communications
    Patent number: 9742469
    Abstract: To promote ease of use, as well as a reduction in bit error rates during extended data exchange between a coupled NFC tag/reader pair, signal strength is measured from a plurality of NFC tag antennas each positioned differently with respect to a common reader field, and differences in signal strength are used to determine an optimum positioning of the tag, or tag emulator, with respect to the reader. Alternative embodiments may include signal time of flight for determining orientation of the NFC antennas within the reader field. Information is generated by the tag, or tag emulator, and output by the tag, or tag emulator, such that a user may direct the positioning of the tag, or tag emulator, for improved communication with the reader.
