    摘要: A method and apparatus for controlling delivery of therapy that includes an emitting portion emitting light at a predetermined emitted light intensity to a volume of tissue at a plurality of wavelengths, and a detecting portion detecting the emitted light scattered by the volume of tissue to generate corresponding detected light intensity output signals. A control module controls the light emission so that an emitted light intensity at each of the plurality of wavelengths is within a predetermined intensity range, and determines a tissue oxygenation index in response to only the detected light intensity output signals, and a therapy delivery module delivers therapy in response to the determined tissue oxygenation index.

    摘要: A method for using a medical device comprising an optical sensor to measure calibrated oxygen saturation in a body tissue uses a standard spectral response of blood established for multiple of oxygen saturations and a standard spectral response of a reference material. The standard responses are established using a spectrometer. The spectral power output of the optical sensor is measured using a spectrometer. The optical sensor output signal response to the reference material is obtained. A processor computes a device-specific calibration curve for the medical device using the measured spectral power output and the standard spectral response of blood and computes an optical gain using the standard spectral response of the reference material and the measured spectral power output of the optical sensor. The device-specific calibration curve and optical gain of the optical sensor are stored in a memory of the medical device.

    摘要: A medical system includes at least two sensing modules that each generate an optical signal that changes as a function of a physiological parameter of a patient. The sensing modules may be coupled to a common light source and a common receiver via an optically transmissive member. At least a first sensing module that is closest to the light source along a length of the optically transmissive member may include a waveguide to split the light emitted by the light source. A first portion of the light may be directed toward the first sensing module and a second portion of the light may be directed toward a second sensing module that is placed downstream of the first sensing module in a direction substantially along the direction of light flow through the optically transmissive member and away from the light source.

    摘要: An implantable medical sensor system provides signals representative of a magnitude of moment fraction applied to a sensor module at a selected site. A sensor module includes a first transducer producing a first signal having an associated first response to pressure and strain applied to the sensor module and a second transducer producing a second signal having an associated second response to pressure and strain applied to the sensor module. A moment fraction is computed in response to the first signal and the second signal. In various embodiments, the moment fraction is used to guide positioning of the sensor module, indicate a need for repositioning the sensor module, report loading of the sensor module during normal operation for use as sensor design information and in setting sensor calibration ranges.

    摘要: A medical device system and associated method monitor tissue hemoglobin concentration. Light attenuation is measured in a volume of tissue in a patient. A value of a tissue scattering coefficient corresponding to the tissue volume in the patient is established in response to the attenuation measurement. A second derivative of the light attenuation measurement is determined. An artifact correction term is computed in response to the established tissue scattering coefficient, and a tissue hemoglobin concentration is computed using the artifact correction term and the second derivative.
