摘要:
The present invention is directed to a method of treating a respiratory or pulmonary condition in a patient by transvascular neuromodulation of an adrenal gland or neural structures that innervate the adrenal gland or components thereof. Methods also include implanting a controller in the patient to control delivery of a therapy signal to the patient's adrenal gland. The therapy signal can be an electrical and/or chemical signal.

A method embodiment comprises generating a neural stimulation signal for a neural stimulation therapy. The signal is generated during a duty cycle of a stimulation period to provide the neural stimulation therapy with an intensity at a therapy level for a portion of the duty cycle. In various embodiments, a ramp up protocol is implemented to begin the duty cycle, a ramp down protocol is implemented to end the duty cycle, or both the ramp up protocol and the ramp down protocol are implemented. The ramp up protocol includes ramping up the intensity from a non-zero first subthreshold level for the neural stimulation therapy at the beginning of the duty cycle to the therapy level. The ramp down protocol includes ramping down the intensity from the therapy intensity level to a non-zero second subthreshold level for the neural stimulation therapy at the end of the duty cycle.

Systems and methods for producing asynchronous neural responses to treat pain and/or other patient conditions are disclosed. A method in accordance with a particular embodiment includes selecting a target stimulation frequency that is above a threshold frequency, with the threshold frequency corresponding to a refractory period for neurons of a target sensory neural population. The method can further include producing a patient sensation of paresthesia by directing an electrical signal to multiple sensory neurons of the target sensory neural population at the stimulation frequency, with individual neurons of the sensory neural population completing corresponding individual refractory periods at different times, resulting in an asynchronous sensory neuron response to the electrical signal.

A neurostimulation device includes an external neurostimulator worn by a patient using a bracing element that braces a portion of the patient's body. The external neurostimulator delivers neurostimulation to modulate a cardiovascular function of the patient. In one embodiment, the external stimulator delivers the neurostimulation transcutaneously to a stimulation target in the patient's body using surface stimulation electrodes placed on the body approximately over the stimulation target.
摘要:
A neural stimulation system delivers neural stimulation to the vagus nerve and senses a signal indicative of laryngeal activity resulting from the neural stimulation. The signal indicative of laryngeal activity is used, for example, to guide electrode placement, determine stimulation threshold, detect lead/electrode problems, detect neural injury, and monitor healing processing following the electrode placement inside the body of a patient.
