Surgery: Light, Thermal, And Electrical Application > Light, Thermal, And Electrical Application > Electrical Therapeutic Systems > Heart Rate Regulating (e.g., Pacing) > Parameter Control In Response To Sensed Physiological Load On Heart > Physical Activity Physical ActivityPhysical Activity patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.11/23/06 - 20060265019 - Rate-adaptive therapy with sensor cross-checking A method and system for automatically adjusting the operating parameters of a rate-adaptive cardiac pacemaker in which maximum exertion levels attained by the patient are measured at periodic intervals and stored in order to compute or update a maximum exercise capacity. The slope of the rate-response curve is then adjusted ... 10/05/06 - 20060224203 - Method and apparatus for evaluating ventricular performance during isovolumic contraction A method of evaluating ventricular performance of a heart employing sensors to measure a ventricular dimension signal and deriving indices of ventricular performance therefrom. Premature Shortening (PS) and Isovolumic Lengthening (IL) comprise two indices of ventricular performance determined from analysis of the left ventricular dimension signal during the transition from ... 09/07/06 - 20060200204 - Calibration of adaptive-rate pacing using intrinsic chronotropic response Calibration of adaptive-rate pacing by a cardiac rhythm management system using an intrinsic chronotropic response. The cardiac rhythm management system may include an adaptive-rate pacing device. The adaptive-rate pacing device may include an adaptive-rate sensor module for measuring an activity level of the individual. A monitor module may be coupled ... 07/20/06 - 20060161211 - Implantable accelerometer-based cardiac wall position detector Methods for evaluating motion of a cardiac tissue location, e.g., heart wall, are provided. In the subject methods, timing of a signal obtain from a accelerometer stably associated with the tissue location of interest is employed to evaluate movement of the cardiac tissue location. Also provided are systems, devices and ... 03/09/06 - 20060052832 - New motion sensor A motion sensor, and an implantable cardiac stimulator incorporating such a motion sensor, has a fluid-type housing containing a fluid that includes at least one type of anisotropic molecules, the anisotropic molecules exhibiting an anisotropic property having a state that changes dependent on motion. The housing of the motion sensor ... 02/16/06 - 20060036292 - Risk of death indicator A system comprising an implantable medical device (IMD). The IMD comprises a ventricular heart signal sensing circuit to provide a ventricular heart signal, at least one sensor operable to provide an electrical signal representative of patient activity, a sensor interface circuit coupled to the at least one sensor to provide ... 02/09/06 - 20060030892 - Cardiopulmonary functional status assessment via heart rate response dectection by implantable cardiac device An implantable cardiac device is configured and programmed to assess a patient's cardiopulmonary function by evaluating the patient's heart rate response. Such evaluation may be performed by computing a heart rate response slope, defined as the ratio of an incremental change in intrinsic heart rate to an incremental change in ... 01/19/06 - 20060015149 - Apparatus and methods for calculating caloric expenditure using posture Systems and methods for estimating caloric expenditure. The systems can include a physiological sensor to measure a patient's physical activity, and a posture sensor to measure the patient's posture. An estimated caloric expenditure can be calculated based on data from the physiological sensor and the posture sensor. For example, the ... ### FreshPatents.com Support |
