  • Patent number: 11890047
    Abstract: Methods for treating anxiety disorders and for reducing a risk associated with developing an anxiety disorder in patients via therapeutic renal neuromodulation and associated systems are disclosed herein. Sympathetic nerve activity can contribute to several cellular and physiological conditions associated with anxiety disorders as well as an increased risk of developing an anxiety disorder. One aspect of the present technology is directed to methods for improving a patient's calculated risk score corresponding to an anxiety disorder status in the patient. Other aspects are directed to reducing a likelihood of developing an anxiety disorder in patients presenting one or more anxiety disorder risk factors. Renal sympathetic nerve activity can be attenuated to improve a patient's anxiety disorder status or risk of developing an anxiety disorder. The attenuation can be achieved, for example, using an intravascularly positioned catheter carrying a therapeutic assembly configured to use, e.g.

  • Patent number: 11167141
    Abstract: Described are a system and method that utilize bioelectric signaling to balance electrical potentials in a subject's body via neuro-hormonal circuit loops, to increase elasticity of the subject's arteries to promote protein release to dampen arterial blood pressure, and to change arterial electrical charges to reduce narrowing of the arteries. The described system is designed to localize and stimulate the fibers inside the vagus nerve without inadvertent stimulation of non-baroreceptive fibers causing side effects like bradycardia and bradypnea. The system also controls release of specific proteins known to lower blood pressures including tropoelastin (known to increase elasticity in the aorta and other peripheral blood vessels).

  • Patent number: 10610689
    Abstract: Systems and methods for reducing ventricle filling volume are disclosed. In some embodiments, a stimulation circuit may be used to stimulate a patient's heart to reduce ventricle filling volume or even blood pressure. When the heart is stimulated at a consistent rate to reduce blood pressure, the cardiovascular system may over time adapt to the stimulation and revert back to the higher blood pressure. In some embodiments, the stimulation pattern may be configured to be inconsistent such that the adaptation response of the heart is reduced or even prevented. In some embodiments, a stimulation circuit may be used to stimulate a patient's heart to cause at least a portion of an atrial contraction to occur while the atrioventricular valve is closed. Such an atrial contraction may deposit less blood into the corresponding ventricle than when the atrioventricular valve is opened throughout an atrial contraction.

  • Patent number: 9814395
    Abstract: Implanted electrodes can be used to deliver electrical stimulation signals to areas near blood vessels, nerves, or other internal body locations. In an example, an electrode can be implanted in a cervical location and can be used to measure dimensional changes in an artery using impedance plethysmography. Measured artery dimensional changes can be used to determine one or more physiological parameters associated with a patient's health status, such as pulse transit time, relative pulse pressure, or aterial compliance, among others. These parameters can be used to monitor a patient health status or to modulate a patient's therapy, among other uses. In some examples, an electrode configured to deliver an electrostimulation signal to nerve tissue can be used to provide non-neurostimulating electrical stimulation plethysmography signals near a blood vessel.

    Abstract: A renal denervation feedback method is described that performs a baseline measurement of renal nerve plexus electrical activity at a renal vessel; denervates at least some tissue proximate the renal vessel after performing the baseline measurement; performs a post-denervation measurement of renal nerve plexus electrical activity at the renal vessel, after the denervating; and assesses denervation of the renal vessel based on a comparison of the baseline measurement and the post-denervation measurement of renal nerve plexus electrical activity at the renal vessel.

  • Patent number: 9421366
    Abstract: The present invention generally relates to patterned intensity modulation of neural tissue. Certain embodiments provide a method of treating medical conditions by providing an electrode and modulating stimulation parameters delivered by the electrode. The stimulation parameters that are modulated relate to stimulation intensity and are varied according to a stimulation input parameter or time. The stimulation input parameter can be a choice of an individual waveform (i.e. ? or psi), which may be varied for each pulse.

  • Patent number: 9399136
    Abstract: An implantable medical device is powered by a battery to deliver one or more therapies including at least one non-life-sustaining therapy such as neural stimulation for enhancing quality of life of a patient. When the battery approaches its end of life, the implantable medical device reduces power consumption of the neural stimulation (e.g., intensity of the neural stimulation) for extending the remaining battery life while maintaining a certain amount of therapeutic benefits for the patient. In one embodiment, the intensity of the neural stimulation is reduced in a tiered manner. In one embodiment in which the implantable medical device also delivers at least one life-sustaining cardiac stimulation therapy, the neural stimulation is disabled or adjusted to reduce its power consumption (e.g., intensity) while the intensity of the cardiac stimulation therapy is maintained when the battery is near its end of life.

  • Patent number: 9289255
    Abstract: Methods and apparatus are provided for renal neuromodulation using a pulsed electric field to effectuate electroporation or electrofusion. It is expected that renal neuromodulation (e.g., denervation) may, among other things, reduce expansion of an acute myocardial infarction, reduce or prevent the onset of morphological changes that are affiliated with congestive heart failure, and/or be efficacious in the treatment of end stage renal disease. Embodiments of the present invention are configured for percutaneous intravascular delivery of pulsed electric fields to achieve such neuromodulation.

  • Patent number: 9126044
    Abstract: In various method embodiments for operating an implantable neural stimulator to deliver a neural stimulation therapy to an autonomic neural target, the method comprises using the implantable neural stimulator to deliver the neural stimulation therapy to the autonomic neural target, and evaluating an evoked response to the neural stimulation bursts.

  • Patent number: RE45718
    Abstract: Systems and methods for blocking nerve impulses use an implanted electrode located on or around a nerve. A specific waveform is used that causes the nerve membrane to become incapable of transmitting an action potential. The membrane is only affected underneath the electrode, and the effect is immediately and completely reversible. The waveform has a low amplitude and can be charge balanced, with a high likelihood of being safe to the nerve for chronic conditions. It is possible to selectively block larger (motor) nerve fibers within a mixed nerve, while allowing sensory information to travel through unaffected nerve fibers.
