  • Patent number: 5869539
    Abstract: The present invention involves perfluoro compound emulsions including nitric oxide, their preparation and their use. These emulsions provide a new source of nitric oxide. Such nitric oxide-containing emulsions may be used for the administration of nitric oxide to individuals in need thereof. Individuals in need of nitric oxide administration can include those suffering from hypertension, preeclampsia and a number of other situations where an increased blood flow, for example, is desirable. In addition, given the long use of perfluoro compound emulsions as blood substitutes, the present invention provides a relatively safe mode for administering and distributing nitric oxide-without potential negative side effects such as toxicities due to drug metabolites.

  • Patent number: 5450857
    Abstract: The present invention relates to a method and instrumentation for detecting the changes in cervical connective tissues associated with cervical dilation or effacement. This method uses an optical system to determine changes by laser or other light induced native fluorescence spectroscopies (LIF) of cervix. The method is non-invasive and instant. It operates by shining excitation light of a selected wavelength on cervical tissue and measuring fluorescent emissions. The measurement is completed in seconds. This method is an excellent fit with the clinical needs for determining the status of cervical dilation.
