  • Patent number: 10188871
    Abstract: A flat optogenetic cuff interface (FOCI) is configured for functional optical stimulation of axons in a single fascicle of a peripheral nerve bundle in which the axons have been genetically modified to express light sensitive proteins for excitation or inhibition of the nerves. The FOCI is configured to gradually reshape the single fascicle to a final height between 0.2 mm and 0.5 mm by reorganizing the individual axons within the fascicle without reshaping (and damaging) the individual axons. The FOCI facilitates stimulation of axons over the entire cross-section of the reshaped fascicle within the power limitations for pulsed laser energy. An electrical interface may be included to sense nerve activity of either the stimulated axons to provide closed-loop feedback to control the optical sources or stimulated axons of a different modality to record the response.

  • Patent number: 10188856
    Abstract: An implantable device for providing electrical stimulation of cervical vagus nerves for treatment of chronic cardiac dysfunction is provided. A stimulation therapy lead includes helical electrodes configured to conform to an outer diameter of a cervical vagus nerve sheath, and a set of connector pins electrically connected to the helical electrodes. A neurostimulator includes an electrical receptacle into which the connector pins are securely and electrically coupled. The neurostimulator also includes a pulse generator configured to therapeutically stimulate the vagus nerve through the helical electrodes in alternating cycles of stimuli application and stimuli inhibition 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.

  • Patent number: 10166395
    Abstract: A method of inhibiting the release of a proinflammatory cytokine in a cell is disclosed. The method comprises treating the cell with a cholinergic agonist. The method is useful in patients at risk for, or suffering from, a condition mediated by an inflammatory cytokine cascade, for example endotoxic shock. The cholinergic agonist treatment can be effected by stimulation of an efferent vagus nerve fiber, or the entire vagus nerve.

  • Patent number: 9993638
    Abstract: Conductors within an implantable medical lead that carry stimulation signal signals are at least partially embedded within a lead body of the medical lead over at least a portion of the length of the conductors while being surrounded by a radio frequency (RF) shield. A space between the shield and the conductors is filled by the presence of the lead body material such that body fluids that infiltrate the lead over time cannot pool in the space between the shield and the conductors. The dielectric properties of the lead body are retained and the capacitive coupling between the shield and the conductors continues to be inhibited such that current induced on the shield is inhibited from being channeled onto the conductors. Heating at the electrodes of the medical lead is prevented from becoming excessive.
