Patents Issued the Week of August 4-8

U.S. Patent No. 12,376,856 entitled “Synthetic Perivascular Wrap” issued August 5, 2025 to Venostent, Inc. of Houston, Texas. Invented by Timothy Boire, Natacha Rodrigues, Colin Dodson, Steven M. Tallman JR., Nick Sears, Bryan Khai Ngo, Laura Rose Emerson, and Geoffrey A. Lucks all of Houston, Texas. Abstract: In one aspect of the present disclosure, devices and methods of treating a vascular anastomosis is disclosed. In one embodiment, the method comprises the steps of: (a) determining the outer diameter of a first vessel to be surgically coupled to a second vessel creating a vascular anastomosis; (b) determining the outer diameter of the second vessel; (c) selecting a perivascular wrap from a plurality of differently sized perivascular wraps such that the perivascular wrap fits around the vascular anastomosis with a constriction of the first vessel of less than 30%; wherein the perivascular wrap includes a shape memory polymer and has at least a first end, a second end, and a medial region; (d) positioning the perivascular wrap onto the first vessel via the first end prior to construction of the vascular anastomosis; (e) coupling the first vessel and the second vessel constructing the vascular anastomosis; and (f) molding the perivascular wrap from a first shape to a second shape wherein the second shape conforms to the geometry of the vascular anastomosis such that the perivascular wrap provides artery-mimetic support to the vascular anastomosis in the range of 0.1-2.0 MPa.

U.S. Patent No. 12,378,682 entitled “Electrolysis Cell Assembly Utilizing an Anion Exchange Membrane” issued August 5, 2025 to FFI IONIX IP, INC. of Wilmington, Delaware. Invented by Bamdad Bahar of Georgetown, Delaware and Jacob Zerby of Dover Delaware. Abstract: An environment control system utilizes oxygen and humidity control devices that are coupled with an enclosure to independently control the oxygen concentration and the humidity level within the enclosure. An oxygen depletion device may be an oxygen depletion electrolyzer cell that reacts with oxygen within the cell and produces water through electrochemical reactions. A desiccating device may be g, a dehumidification electrolyzer cell, a desiccator, a membrane desiccator or a condenser. A controller may control the amount of voltage and/or current provided to the oxygen depletion electrolyzer cell and therefore the rate of oxygen reduction and may control the amount of voltage and/or current provided to the dehumidification electrolyzer cell and therefore the rate of humidity reduction. The oxygen level may be determined by the measurement of voltage and a limiting current of the oxygen depletion electrolyzer cell. The enclosure may be a food or artifact enclosure.

U.S. Patent No. D1,087,519 entitled “Trailer Winch” issued August 5, 2025 to Tractor Supply Co. of Texas, LP of Brentwood, Tennessee. Invented by Christian D. Fogg of Columbia, Tennessee, Jace A. McDill of Nashville, Tennessee and Qinpeng Cui of Ningbo City, China. Claims: The ornamental design for a trailer winch as shown and described.

U.S. Patent No. D1,087,176 entitled “Winch” issued August 5, 2025 to Tractor Supply Co. of Texas, LP of Brentwood, Tennessee. Invented by Christian D. Fogg of Columbia, Tennessee, Jace A. McDill of Nashville, Tennessee and Zhilin Yu of Zhejiang Province, China. Claims: The ornamental design for a winch as shown and described.

U.S. Patent No. 12,379,174 entitled “Firearm” issued August 5, 2025 to CR3 LLC of Naples, Florida. Invented by Caleb Crye of Brooklyn, New York. Abstract: A compact rifle-caliber firearm is provided herein comprising a receiver body, a barrel, and a grip. The barrel is coupled to the receiver body and extends in a forward direction relative to the receiver body. The barrel includes a bore and a bore axis. The grip is coupled to the receiver body and positioned rearward relative to the barrel. The grip is operable to accept a magazine sized for rifle cartridges. The grip includes a grip depth that is less than or equal to two inches. The compact rifle-caliber firearm may further include a magazine operable to be inserted into the grip and operable to receive rifle cartridges. An interior magazine depth may be less than a length of the rifle cartridges. Rifle cartridges positioned in the magazine may be angled relative to an uppermost cartridge.
