  • Publication number: 20240108240
    Abstract: A display system configured to communicate tissue proximity data from a plurality of electrodes includes a display. The display outputs a circular graphical representation. The circular graphical representation includes a plurality of color areas forming a first circular shape. Each of the color areas communicate a categorized value for a respective electrode indicative of tissue proximity for the respective electrode. A plurality of graph areas form a second circular shape. Each of the graph areas communicate a relative value for the respective electrode indicative of the tissue proximity for the respective electrode.

  • Patent number: 11931095
    Abstract: A method of determining a baseline impedance value for a first electrode in a plurality of electrodes located on a medical device for tissue contact detection includes measuring an impedance value of the first electrode generated in response to a drive signal to the first electrode. The method further includes assigning a baseline impedance value to the first electrode based on impedance values measured in a predetermined time interval and determining a confidence value associated with the baseline impedance value. The method further includes utilizing the baseline impedance value in determining contact status of the first electrode when the confidence value is at or above a predetermined threshold value.

  • Patent number: 11613710
    Abstract: A treatment process for remediating H2S and other contaminants in liquids includes: partially filling a closed vessel with a contaminated liquid containing ?5 ppm H2S with a head space above the liquid within the vessel where gasses released from the liquid from the liquid collect; separately providing a treatment composition in the head space so that the gasses from the liquid may contact the treatment composition; and permitting the contact between the vapors from the liquid and the treatment composition to continue until a collective concentration of H2S in the liquid and in the head space is <5 ppm. The treatment composition includes an aqueous solution containing at least one hydroxide compound, a collective concentration of the at least one hydroxide compound in the aqueous solution is in a range of 35-55 weight %, and the aqueous solution constitutes at least 80 weight % of the treatment composition.
