摘要： Described here are devices, systems, and methods for improving left ventricular function in a patient with systolic heart failure with left ventricular dysfunction using baroreflex activation therapy. In general the systems have at least one electrode and a control system in communication with the electrode, the control system including a processor and memory, wherein the memory includes software defining a stimulus regime configured to effect improvement in left ventricular function. The methods for improving left ventricular function in a subject typically include identifying a patient in need of left ventricular function improvement and stimulating a baroreceptor with a baroreceptor activation device to improve left ventricular function.

摘要： Systems and methods provide baroreflex activation to treat or reduce pain and/or to cause or enhance sedation or sleep. Methods involve activating the baroreflex system to provide pain reduction, sedation, improved sleep or some combination thereof. Systems include at least one baroreflex activation device, at least one sensor for sensing physiological activity of the patient, and a processor coupled with the baroreflex activation device(s) and the sensor(s) for processing sensed data received from the sensor and for activating the baroreflex activation device. In some embodiments, the system is fully implantable within a patient, such as in an intravascular, extravascular or intramural location.

摘要： Devices, systems and methods are described which control blood pressure, nervous system activity, and neurohormonal activity by activating baroreceptors. By selectively and controllably activating baroreceptors, the present invention reduces excessive blood pressure, sympathetic nervous system activity and neurohormonal activity, thereby minimizing their deleterious effects on the heart, vasculature and other organs and tissues. A baroreceptor activation device is positioned near a low-pressure baroreceptor, preferably in the venous system, heart, or pulmonary vasculature.

摘要： A tissue stimulation device includes an electrode array having at least four independently switchable electrodes. In one embodiment, the electrode array comprises a flexible base to which the electrodes are fixed that flexes to encompass at least a portion of an artery or other elongate biological structure. The electrodes are electrically coupled to and energized by a signal generator coupled to a control system. In one embodiment, the array of electrodes are configured such that a suitable signal pattern for stimulation pulses between or among a set of the switchable electrodes may be determined without having to reposition the electrode assembly by using a series of signal patterns activating different combinations of switchable electrodes in response to sub-stimulation test signals to determine a signal pattern that provides suitable patient response. In another embodiment, the array of electrodes includes an array of selectively activatable multi-polar electrodes.
