  • Patent number: 8346353
    Abstract: An implantable medical system for detecting incipient edema has an implantable medical lead including an optical sensor having a light source and a light detector. The medical system further has an edema detection circuit that activates the light source to emit light, the light being directed into lung tissue of a patient and that obtains a light intensity value corresponding to an intensity of light received by the light detector, and that evaluates the light intensity value to detect a consistency with incipient edema.

  • Publication number: 20100185252
    Abstract: In a device and method for a medical implant for monitoring progression of heart failure in a human heart, an activity sensor provides information related to the activity level of a patient and an oxygen sensor provides information related to the level of oxygen content in venous blood. A determined level of venous oxygen content at a determined activity level is obtained, and that level of venous oxygen content is compared to stored values at a corresponding activity level. The result of the comparison is used as a basis for determining a degree of heart failure.

  • Publication number: 20100041970
    Abstract: An implantable medical device has an oxygen sensor adapted to measure the level of oxygen in oxygenized blood, and to generate an oxygen measurement signal in dependence of the level of oxygen. The oxygen sensor is adapted to perform measurements inside the heart, of blood entering the left atrium of a patient's heart. The obtained oxygen measurement signal is compared to a predetermined threshold level and an indication signal is generated in dependence of the comparison. The, indication signal is indicative of the lung functionality of the patient.
