Pulse Signal Patents (Class 607/72)
  • Patent number: 10232178
    Abstract: Devices, systems and methods are disclosed for treating or preventing dementia, such as Alzheimer's disease. The methods comprise transmitting impulses of energy non-invasively to selected nerve fibers, particularly those in a vagus nerve, that modulate the activity of a patient's locus ceruleus. The transmitted energy impulses, comprising magnetic and/or electrical energy, stimulate the selected nerve fibers to cause the locus ceruleus to release norepinephrine into regions of the brain that contain beta-amyloids. The norepinephrine counteracts neuroinflammation that would damage neurons in those regions and the locus ceruleus, thereby arresting or slowing the progression of the disease in the patient.

    Abstract: The present invention is an implantable electrode array having electrodes with variable pitch and variable size. Electrode arrays of the prior art provide electrodes with a common spacing and size. However, this is not how the human body is arranged. As an example, the retina has closely spaced retinal receptors near the fovea. Those receptors are spaced farther apart, farther away from the fovea. Further, the amount of electrical current required to stimulate the perception of light increases with distance from the fovea. Hence, larger electrodes are required to transfer the necessary current farther away from the fovea.

  • Patent number: 8996137
    Abstract: Described here are devices, systems, and methods for treating one or more conditions (such as dry eye) or improving ocular health by providing stimulation to nasal or sinus tissue. Generally, the devices may be handheld or implantable. In some variations, the handheld devices may have a stimulator body and a stimulator probe having one or more nasal insertion prongs. When the devices and systems are used to treat dry eye, nasal or sinus tissue may be stimulated to increase tear production, reduce the symptoms of dry eye, and/or improve ocular surface health.

  • Publication number: 20150073495
    Abstract: Systems and methods for stimulation of neurological tissue generate stimulation trains with temporal patterns of stimulation, in which the interval between electrical pulses (the inter-pulse intervals) changes or varies over time. Compared to conventional continuous, high rate pulse trains having regular (i.e., constant) inter-pulse intervals, the non-regular (i.e., not constant) pulse patterns or trains that embody features of the invention provide a lower average frequency.

  • Publication number: 20150073512
    Abstract: An implantable device (11) for evaluating autonomic cardiovascular drive in a patient (10) suffering from chronic cardiac dysfunction is provided. A stimulation therapy lead (13) includes helical electrodes (14) configured to conform to an outer diameter of a cervical vagus nerve sheath, and a set of connector pins (28) electrically connected to the helical electrodes (14). A neurostimulator (12) includes an electrical receptacle (25) into which the connector pins (28) are securely and electrically coupled. The neurostimulator (12) also includes a pulse generator configured to therapeutically stimulate the vagus nerve through the helical electrodes (14) in alternating cycles of stimuli application and stimuli inhibition (90) that are tuned to both efferently activate the heart's intrinsic nervous system and afferently activate the patient's central reflexes by triggering bi-directional action potentials. The neurostimulator (12) includes a recordable memory (29) storing a baseline heart rate.

  • Publication number: 20150066109
    Abstract: Methods for electrically stimulating body tissues to improve function or reduce symptoms provide an electrical stimulation system having two or more electrodes that are capable of being switched independently from a hyperpolarizing (depolarizing) state to a hypopolarizing state. Multiple combinations of hyperpolarizing electrodes and hypopolarizing electrodes are created by polarity switching to determine a polarity configuration having the best performance as determined by symptom reporting and clinical diagnostic tests. Polarity switching is triggered manually or is programmed to be switched automatically. Determining the configuration providing electrical stimulation resulting in the greatest benefit allows the system to be operated with one or more electrodes in a hypopolarizing state, thereby reducing energy requirements, tissue tolerance, and tissue fatigue.

    Abstract: Selective high-frequency spinal chord modulation for inhibiting pain with reduced side affects and associated systems and methods are disclosed. In particular embodiments, high-frequency modulation in the range of from about 1.5 KHz to about 50 KHz may be applied to the patient's spinal chord region to address low back pain without creating unwanted sensory and/or motor side affects. In other embodiments, modulation in accordance with similar parameters can be applied to other spinal or peripheral locations to address other indications.

  • Patent number: 8958871
    Abstract: Methods and apparatus are provided for pulsed electric field neuromodulation via an intra-to-extravascular approach, e.g., to effectuate irreversible electroporation or electrofusion, necrosis and/or inducement of apoptosis, alteration of gene expression, changes in cytokine upregulation and other conditions in target neural fibers. In some embodiments, the ITEV PEF system comprises an intravascular catheter having one or more electrodes configured for intra-to-extravascular placement across a wall of patient's vessel into proximity with target neural fibers. With the electrode(s) passing from an intravascular position to an extravascular position prior to delivery of the PEF, a magnitude of applied voltage or energy delivered via the electrode(s) and necessary to achieve desired neuromodulation may be reduced relative to an intravascular PEF system having one or more electrodes positioned solely intravascularly.

  • Patent number: 8948878
    Abstract: A method and device for treating a condition aggravated by the presence of amyloid fibrils is disclosed. The method includes applying a plurality of ultra-short pulses to target tissue comprising amyloid fibrils. The plurality of ultra-short pulses produce an electric field in the target tissue sufficient to change a molecular structure of the amyloid fibrils without causing the death, destruction, or serious injury of healthy cells surrounding the target tissue. For example, the plurality of ultra-short pulses can be sufficient to change the molecular structure of amyloid fibrils without causing apoptosis or necrosis of surrounding cells. The ultra-short pulses can be applied using an electrode device or a wideband antenna. The ultra-short pulses can have a duration ranging from 1 ps to 10 ns, an amplitude ranging from 100 V to 1 MV, and can apply an electrical field to the target tissue ranging from 1 kV/cm to 1 MV/cm.
