Patent number: 11980408Abstract: An intravascular catheter for peri-vascular and/or peri-urethral tissue ablation includes multiple needles advanced through supported guide tubes which expand with open ends 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 also includes means to limit and/or adjust the depth of penetration of the ablative fluid into and beyond the tissue of the vessel wall. The preferred embodiment of the catheter includes structures which provide radial and lateral support to the guide tubes so that the guide tubes open 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: GrantFiled: September 5, 2019Date of Patent: May 14, 2024Assignee: 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

Patent number: 11911557Abstract: A heating element for a vaporizer cartridge is provided. The vaporizer cartridge may include a reservoir containing vaporizable material and a wicking element in fluid communication with the reservoir. The heating element may include a heating portion, a cartridge contact, and a leg. The heating portion includes at least two tines spaced apart from one another. The cartridge contact may be in in electrical communication with a power source. The leg extends between the heating portion and the cartridge contact. The heating portion may be crimped around the wicking element such that the heating portion secures the wicking element to the heating element and contacts at least two surfaces of the wicking element.Type: GrantFiled: January 28, 2021Date of Patent: February 27, 2024Assignee: JUUL Labs, Inc.Inventors: Ariel Atkins, Christopher L.

Patent number: 8015159Abstract: A method and system for continually storing and cataloguing streams of broadcast content, allowing real-time searching and real-time results display of all catalogued video. A bank of video recording devices store and index all video content on any number of broadcast sources. This video is stored along with the associated program information such as program name, description, airdate and channel. A parallel process obtains the text of the program, either from the closed captioning data stream, or by using a speech-to-text system. Once the text is decoded, stored, and indexed, users can then perform searches against the text, and view matching video immediately along with its associated text and broadcast information. Users can retrieve program information by other methods, such as by airdate, originating station, program name and program description.Type: GrantFiled: November 29, 2007Date of Patent: September 6, 2011Assignee: DNA 13 Inc.Inventors: Trevor Nelson Boicey, Christopher James Johnson
