An implantable medical device, having a neural stimulator adapted to generate neural stimulation signals, an electrode configuration tester for testing a first electrode configuration for stimulating a desired neural target, and a controller. The controller is configured to control the neural stimulator to selectively provide a first neural stimulation signal with appropriate signal characteristics to stimulate the desired neural target using the first electrical configuration and a second neural stimulation signal with appropriate signal characteristics to stimulate the desired neural target using a second electrode configuration, and adapted to communicate with the electrode configuration tester and to respond to an indication that an efficacy of the first electrode configuration is lower than a threshold by providing the neural stimulation using the second neural stimulation signal.

A method and device for delivering and monitoring baroreflex and drug therapy to manage hypertension. The method includes providing an implanted an implanted medical device configured to automatically detect drug-related effects on the autonomic nervous system including the steps of measuring a physiologic status of the autonomic nervous system at desired intervals, logging the physiologic status of the autonomic nervous system at desired intervals, monitoring the measured and logged physiologic status of the autonomic nervous system for any changes and correlating the changes to a corresponding drug administration time. The device includes an implanted baroreflex activation device capable of administering one or more hypertension treatment drugs including a controller that activates and adjusts therapy delivery, a baroreflex activation therapy delivery device, a drug therapy delivery device and a device that senses physiologic parameters.

Devices, systems and methods are described by which the blood pressure, nervous system activity, and neurohormonal activity may be selectively and controllably reduced by activating baroreceptors. A baroreceptor activation device is positioned near a baroreceptor, preferably a baroreceptor located in the carotid sinus. A control system may be used to modulate the baroreceptor activation device. The control system may utilize an algorithm defining a stimulus regimen which promotes long term efficacy and reduces power requirements/consumption. The baroreceptor activation device may utilize electrodes to activate the baroreceptors. The electrodes may be adapted for connection to the carotid arteries at or near the carotid sinus, and may be designed to minimize extraneous tissue stimulation.

The present invention comprises a neural stimulator having an output to deliver neural stimulation pulses, a sensor to sense a reference signal indicative of cardiac cycles each including a predetermined type timing reference event, the sensor being external to the circulatory system. The neural stimulator further includes detection circuitry coupled to the sensor to detect the predetermined type timing reference event, and a control circuit having an offset interval generator and a pulse delivery controller.

A monitoring device is provided to monitor a patient. The monitoring device includes at least one lead having an electrode. The lead is positioned proximate a location within the patient's body, and the lead is adapted to sense cardiac electrical activity. The monitoring device also includes a control system coupled to the at least one lead to receive a signal representative of the cardiac electrical activity.

607117, 607116

An electrode assembly for an implantable medical device, including a spine, and a plurality of electrodes protruding from the spine. At least two electrodes protrude from the spine in opposing directions and define a nerve-receiving channel. When the electrode assembly is not coupled to a nerve and the electrodes are in a relaxed state position, the nerve receiving channel comprises a cross-sectional area that is substantially less than a cross-sectional area of a nerve to which the electrode assembly is adapted to be coupled. And when coupled to the nerve, each electrode wraps around and directly contacts at least 60% of the circumference of the nerve.
