    摘要： A body fluid pressure sensor module according to the invention comprises a housing having a first end and a second end and enclosing a pressure sensor. The pressure sensor is electrically coupled to a plurality of electrical conductors extending into the housing through a feedthrough disposed within, and hermetically sealing, the first end of the housing. The housing defines a chamber disposed between the feedthrough and the second end of the housing. The chamber contains a material in communication with the pressure sensor, the material being capable of transmitting pressure variations to the pressure sensor. The plurality of electrical conductors have ends within the housing, and the pressure sensor is mounted on the end of at least one of the conductors. Also disclosed are medical leads incorporating the pressure sensor module, and methods for fabricating the modules. The pressure sensor module is compact, and particularly so where cable conductors are utilized and the sensor is directly mounted on at least one of the cable conductors. The compactness of a pressure sensor module pursuant to the invention facilitates its incorporation into a small diameter, flexible medical lead enhancing its placement within a patient's body, for example, within the left atrium of the heart.

    摘要： An intravenous implantable optical sensor assesses the relative absorbance of multiple wavelengths of light in order to determine oxygen saturation. The calculation of oxygen saturation is enhanced by use of a function of hematocrit which is derived from the relative absorbance of light of an isobestic wavelength along two different length paths through the blood. The use of the hematocrit-dependent term and multiple wavelengths of light to calculate oxygen saturation provides results that are less susceptible to noise and variation in hematocrit and thus provides a more accurate measure of oxygen saturation over a wider range of conditions than previously possible. The optical sensor may form part of an implantable system which performs the calculation of oxygen saturation and uses the results for a diagnostic or therapeutic purpose.

    摘要： Methods of processing venous oxygen saturation and hematrocrit information in an implantable sensor are provided. In an embodiment a method for collecting data from an implantable multi-wavelength SvO2 sensor having multiple light sources is provided. The method includes receiving a frame signal that indicates a beginning of the light sources being turned on and receiving a light source signal that indicates a light source is on. The output of a photodetector is sampled to measure the intensity of the transmitted light. The process is repeated for each light source to gather intensity measurements that then can be used to generate venous oxygen saturation and hematocrit measurements.

    摘要： A measurement light detector detects light transmitted by a light source of an implantable system that is scattered back into an implantable housing, and produces a measurement signal indicative of the intensity of the light detected by the measurement light detector. A calibration light detector detects a portion of the transmitted light that has not exited the housing, and produces a calibration signal that is indicative of the intensity of the light detected by the calibration light detector, which is indicative of the intensity of the light transmitted by the light source. Changes in the intensity of the transmitted light are compensated for based on the calibration signal produced by the calibration light detector. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
