  • System and method for controlling oxygen-enrichment therapy based on microvascular resistance feedback
    Patent number: 12653936
    Abstract: The present disclosure provides systems and methods for controlling gas-enrichment, e.g., oxygen-enrichment, therapy. One or more sensors and/or one or more imaging systems may be used to measure or determine one or more physiological parameters of the patient. Feedback regarding one or more physiological parameters or microvascular resistance may be provided for titrating or controlling the gas-enrichment therapy.
    Type: Grant
    Filed: March 10, 2023
    Date of Patent: June 16, 2026
    Assignee: Zoll Circulation, Inc.
    Inventors: Jeffrey Lance Creech, Stephen Elwood Myrick, Richard A. Helkowski, Fred Shen, Ramu Perumal, Gary A. Freeman
  • Radial Access Systems and Methods for Delivery of Gas-Enrichment Therapy
    Publication number: 20230405200
    Abstract: Methods and systems for delivering gas-enriched blood within a vasculature of a patient may include providing a gas-enrichment system, the gas-enrichment system comprising a mixing chamber and a blood pump. The process may include inserting a catheter for drawing blood from the patient into a radial artery of the patient. The process may include drawing blood from the radial artery or from a vessel upstream of the radial artery at a blood flow rate without collapsing the artery or vessel to a degree that would substantially impede drawing blood. The process may include generating a gas-enriched blood by mixing the withdrawn blood with a gas-enriched liquid in a mixing chamber. The process may include delivering the gas-enriched blood to the vasculature of the patient.
