Norbert Weiler has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Regional oxygen uptake/perfusion measuring device and method
    Patent number: 8808193
    Abstract: To assess regional oxygen uptake and/or perfusion in a patient, a volume of air inhaled by the patient is determined and, according to a method of electrical impedance tomography, a first regional lung volume is measured at a first time point of a breathold procedure. The first regional lung volume is compared to a second regional lung volume at a second time point of the breathold procedure.
    Type: Grant
    Filed: September 8, 2008
    Date of Patent: August 19, 2014
    Assignee: Carefusion 207, Inc.
    Inventor: Norbert Weiler

  • Magnetic resonance imaging method
    Patent number: 6595211
    Abstract: The invention provides a method of detecting regional variations in oxygen uptake from the lungs of an air-breathing animal subject, said method comprising administering into the lungs of said subject a diagnostically effective amount of a gaseous hyperpolarized magnetic resonance imaging agent, detecting the magnetic resonance signal from said agent in said lungs, determining the temporal variation in relaxation rate for said signal for at least one region of interest within said lungs, and from said variation generating a qualitative or quantitative value or image indicative of the oxygen uptake from the alveolar space in said at least one region of interest.
