  • Patent number: 6472390
    Abstract: Patients with pathologic conditions involving constriction or proliferation of smooth muscle or disease associated with cysteine containing proteins, or who are at risk for such, are administered a therapeutically effective amount of a nitric oxide (NO) donor which is insufficient to acutely lower mean arterial blood pressure or pulmonary artery pressure by more than 10%. In one subgenus, NO donor is administered to modify red blood cell membrane receptors to prevent red blood cells from causing vasoconstriction. A related method which allows increased dosage of NO donor without acutely lowering mean arterial blood pressure comprises administering the NO donor into an artery of the patient. In another method, patients having a cardiovascular syndrome, or who are at risk for such, are administered a therapeutically effective amount of thiol which does not acutely affect blood pressure to a significant degree.

  • Patent number: 6287452
    Abstract: Nitric oxide-specific electrodes are useful for in situ detection of nitric oxide in biomedical applications and have at least a surface region thereof which is capable of forming complexes with nitric oxide, for example, nitrosyl complexes. The nitric oxide complexes formed at the surface of the electrodes apparently increase the concentration of nitric oxide available for detection, thereby leading to significantly improved relative responses as compared to other known nitric oxide electrode materials. Most preferably, the electrode has at least an exterior surface region which contains ruthenium and/or at least one oxide of ruthenium. The electrodes are advantageously conditioned in saline solution at +675 mV for about two hours.

The nitric oxide complexes formed at the surface of the electrodes apparently increase the concentration of nitric oxide available for detection, leading to significantly improved relative responses as compared to other known nitric oxide electrode materials. The electrode has at least an exterior surface region which contains ruthenium and/or at least one oxide of ruthenium. The electrodes are pre-conditioned at a potential, or potentials, different than the working potential of the electrode, followed by further conditioning at the working potential. Direct response to nitric oxide has been observed for ruthenium electrodes at or below potentials about +675 mV vs. Ag/AgCl, while ruthenium electrodes paradoxical response to nitric oxide has been observed at potentials above +675 mV vs. Ag/Cl.

  • Patent number: 5282467
    Abstract: A non-invasive method for detecting deep venous thrombosis in a human body wherein changes are effected in the amount of deoxyhemoglobin in the body limb by trapping blood in the venous system for a determinate time period and then releasing the trapped blood in the venous system. During the period that the changes in the amount of deoxyhemoglobin are effected, first and second light sources emit light of two selected wavelengths which penetrate into the deep venous system of the body limb so that the reflectance contributions can be used to measure changes in the flow and amount of deoxyhemoglobin and to thereby detect the presence or absence of deep venous thrombosis.

  • Patent number: 5161531
    Abstract: A method and apparatus for measuring oxidative metabolism in an internal organ or tissue of interest wherein a percutaneous intravascular approach is utilized to bring a light-transmitting and receiving scope into contact with the site to be assessed. The tip of the scope is adapted so that the light-transmitting optical fiber(s) and light-receiving optical fiber(s) are in divergent relationship so as to increase the photon pathlength through the tissue of interest to provide optical information from a substantial volume of tissue relative thereto.
