| 20100076519 | SYSTEM AND METHOD FOR REGULATING BLOOD PRESSURE AND ELECTROLYTE BALANCE - The present invention is an apparatus and method for controlling blood pressure by stimulating the cardiac afferent sympathetic nerves. The invention may be implemented in a medical device having a pressure sensor for sensing blood pressure, an electrode for providing electrical signals to the cardiac afferent sympathetic nerves, and a controller for providing signals to the electrode as a function of blood pressure signals received from the pressure sensor. | 03-25-2010 |
| 20100114254 | SUBCLAVIAN ANSAE STIMULATION - Techniques for improving cardiac performance by applying stimulation to the subclavian ansae nerve of a patient are disclosed. In one example, a method comprises identifying a human patient as having a cardiac condition, and delivering stimulation therapy to a subclavian ansae nerve of a human patient with a stimulation electrode. | 05-06-2010 |
| 20100241184 | POST LONG PAUSE OVERDRIVE PACING IN RESPONSE TO ATRIAL TACHARRHYTHMIA EPISODE - This disclosure provides for methods and apparatus for preventing an early recurring atrial fibrillation and atrial flutter (AF) episode (herein “ERAF”). Some aspects of the foregoing involve commencing atrial overdrive pacing therapy delivery at an overdrive pacing rate upon detection of one of: (i) an AF episode and (ii) a relatively long pause between successive sensed P-waves during an AF episode. The AF episode typically has a cycle length interval of between about 100 ms and 300 ms, and the relatively long pause has a duration of between about 40 ms and 100 ms longer than the cycle length of the AF episode. Atrial overdrive pacing is delivered for a relatively short period of time after successful termination of the AF episode. Subsequently, the atrial pacing rate is rapidly decreased until either normal sinus rhythm or a lower programmed pacing rate is reached. | 09-23-2010 |
| 20110022107 | AUTOMATIC ENABLING OF POST LONG PAUSE OVERDRIVE PACING - A method and apparatus for controlling an atrial overdrive pacing therapy include detecting an atrial arrhythmia episode and determining if the atrial arrhythmia episode is an early recurring episode. Delivery of the atrial overdrive pacing therapy is enabled in response to the early recurring episode and commences upon detection of an atrial arrhythmia episode or a long pause. | 01-27-2011 |
| 20110024186 | LEAD APPARATUS - A lead including one or more electrodes (e.g., electrodes, such as those having circuitry associated therewith). | 02-03-2011 |
| 20110105926 | HEART RATE VARIABILITY DISTINCTION - Systems, methods and devices for monitoring, analyzing, and processing a patient's heart rate signal for HRV characteristics are described herein. A first heart rate signal is acquired. The first heart rate signal includes at least one indication of an interval duration of cardiac activity. At least one accelerating portion and at least one decelerating portion of the first heart rate signal are identified. An average heart rate signal is acquired. The accelerating portion or the decelerating portion of the first heart rate signal is replaced with the average heart rate signal to produce a second heart rate signal. A frequency spectrum of the second heart rate signal may be obtained and utilized to predict or detect one or more autonomic conditions of a patient. Therapy may initiated or titrated in response to prediction or detection of the autonomic condition. | 05-05-2011 |
| 20110106195 | ARRHYTHMIA PREDICTION BASED ON HEART RATE TURBULENCE - In general, the disclosure describes techniques for predicting the occurrence of an arrhythmia based on an indication of heart rate turbulence. An example method comprises sensing a parameter indicative of heart rate turbulence, measuring heart rate turbulence based on the sensed parameter, and predicting an occurrence of an arrhythmia based on the measured heart rate turbulence. | 05-05-2011 |
| 20110270332 | THERAPY USING PERTURBATION AND EFFECT OF PHYSIOLOGICAL SYSTEMS - Methods for treating a patient and further to devices for performing such treatment, e.g., methods and devices to perturb at least one physiological system and deliver therapy to the patient based on the effects of such perturbation.
