20080269822 | Device for Evaluating Positions of an Implantable Medical Device - In a device and method for evaluating positions of a medical lead during an implantation procedure, an IEGM signal and a signal indicative of heart pumping activity are obtained for each of a number of different lead positions, and those signals are stored dependent on the different lead positions. A processor automatically determines a lead position, from among the stored lead positions, that results in most favorable hemodynamics of the heart, based on the IEGM signal and the pumping activity signal. | 10-30-2008 |

20100041970 | IMPLANTABLE MEDICAL DEVICE - 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. | 02-18-2010 |
20100106210 | IMPLANTABLE MEDICAL SYSTEM FOR DETECTING INCIPIENT EDEMA - 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. | 04-29-2010 |
20100121400 | IMPLANTABLE CARDIAC DEVICE AND METHOD FOR MONITORING THE STATUS OF A CARDIOVASCULAR DISEASE - An implantable cardiac device has a heart stimulator for electrically stimulating the heart of a patient, detector that measures a physiologic parameter that is affected by the status of a cardiovascular disease associated with sympathetic activation, a signal processor that determines at least one of a low frequency, LF, and a very low frequency, VLF, Mayer wave component in the measured parameter, and analyzer that automatically analyzes the determined Mayer wave component in relation to a predetermined reference value to determine the status of the cardiovascular disease. The detector is a cardio-mechanical parameter detector that measures, as said physiologic parameter, a mechanical change in at least one of the four chambers of the heart. In a corresponding method for monitoring the status of a cardiovascular disease associated with sympathetic activation of a patient having an implantable electric heart stimulator a physiologic parameter affected by the cardiac disease is measured. At least one of a low frequency, LF, and a very low frequency, VLF, Mayer wave component in the parameter is determined, and the wave component is analyzed in relation to a predetermined reference value to determine the status of the cardiovascular disease. A mechanical change in at least one of the four chambers of the heart is measured as the physiologic parameter. | 05-13-2010 |
