Patent number: 12245790Abstract: An intravascular catheter for peri-vascular or peri-urethral tissue ablation includes multiple needles advanced through supported guide tubes which expand around a central axis to engage the interior surface of the wall of the renal artery or other vessel of a human body allowing the injection an ablative fluid for ablating tissue, or nerve fibers in the outer layer or deep to the outer layer of the vessel, or in prostatic tissue. A method can involve injection/infusion of the ablative fluid over an extended time period of at least 10 seconds or with two injections at two different penetration depths to reduce or eliminate patient pain during ablation.Type: GrantFiled: August 4, 2020Date of Patent: March 11, 2025Assignee: Ablative Solutions, Inc.Inventors: David R. Fischell, Tim A. Fischell, Robert Ryan Ragland, Darrin James Kent, Andy Edward Denison, Eric Thomas Johnson, Jeff Alan Burke, Christopher Scott Hayden, Robert E. Fischell

Publication number: 20250072933Abstract: An intravascular catheter for peri-vascular and/or peri-urethral tissue ablation includes multiple needles advanced through supported guide tubes which expand around a central axis to engage the interior surface of the wall of the renal artery or other vessel of a human body allowing the injection an ablative fluid for ablating tissue, and/or nerve fibers in the outer layer or deep to the outer layer of the vessel, or in prostatic tissue. The system may also include a means to limit and/or adjust the depth of penetration of the ablative fluid into and beyond the tissue of the vessel wall. The catheter may also include structures which provide radial and/or lateral support to the guide tubes so that the guide tubes expand uniformly and maintain their position against the interior surface of the vessel wall as the sharpened injection needles are advanced to penetrate into the vessel wall.Type: ApplicationFiled: October 31, 2024Publication date: March 6, 2025Inventors: David R. Fischell, Tim A. Fischell, Robert Ryan Ragland, Darrin James Kent, Andy Edward Denison, Eric Thomas Johnson, Jeff Alan Burke, Christopher Scott Hayden, Robert E. Fischell

Publication number: 20250029313Abstract: A computer implemented method for rendering a table is described. The table includes intersections formed by a plurality of lines, each of the plurality of lines associated with at least a first attribute. The method includes, for one or more of the intersections, matching a value of the first attribute of a first line of the plurality of lines with a value of the first attribute for at least a second line of the plurality lines, wherein the second line is different to the first line and based on the matching, rendering a displayed area of the intersection with a value for the first attribute that matches the value of the first attribute of the first line. The value of the first attribute defines an appearance of the line, for example the line fill colour, when the table is rendered on a display device.Type: ApplicationFiled: October 4, 2024Publication date: January 23, 2025Applicant: Canva Pty LtdInventor: Cieran James Kent

Patent number: 12178966Abstract: Caloric stimulation and pressure stimulation can be applied to the ear for treatment of neurological disorders, such as migraine, pain, and headache. Heat can be applied first to increase the sensitivity of the mechanoreceptors in the ear. The pressure can be applied after heating to produce a stronger neurological response than would occur without the heating. In some cases, cooling can be used. Valves can be used to direct fluid flow to a right ear, a left ear, or both. Valves can be used to transition the system between an irrigation or caloric mode and a pressure mode. Green eyewear can be used for therapeutic relief.Type: GrantFiled: December 10, 2020Date of Patent: December 31, 2024Assignee: NOCIRA, LLCInventors: David Mager George, John Patrick Claude, Kevin E.

Publication number: 20240148983Abstract: A device for performing injections in a patient includes a syringe holder with a needle guard, a cannula extending from the syringe holder, a needle slidably disposed over the cannula, and a slider on the syringe holder. The cannula has a blunt tip and a cannula length, and the needle has a sharp tip and a needle length that is shorter than the cannula length. The slider is coupled with the needle and is configured to slide the needle along the cannula from an extended position, in which the sharp tip of the needle is located at or immediately adjacent the blunt tip of the cannula, to a retracted position, in which the sharp tip is housed within the needle guard of the syringe holder.Type: ApplicationFiled: January 8, 2024Publication date: May 9, 2024Applicant: Arya Medical, Inc.Inventors: John P.
