Assignee:

Cyberonics, Inc. - Houston TX

International Classification:

A61N 1/365

US Classification:

607 9

Abstract:

A vagus nerve neurostimulator system with multiple patient-selectable modes for treating chronic cardiac dysfunction is provided. An implantable neurostimulator includes a pulse generator coupled to a therapy lead terminated by a pair of helical electrodes positioned over a cervical vagus nerve. The pulse generator is configured to deliver through the helical electrodes continuously-cycling, intermittent and periodic electrical stimulation that is parametrically defined to bi-directionally propagate through nerve fibers in the cervical vagus nerve. The implantable neurostimulator includes a magnetic switch configured to switch the pulse generator between a plurality of operating modes that are each separately selectable in response to a unique and remotely-applied magnetic signal. An external controller includes patient-actuatable controls configured to enable selection of one of the operating modes of the pulse generator. The external controller includes an electromagnetic transmitter configured to output the magnetic signal uniquely associated with the operating mode as selected with the controls.

US Classification:

607 27, 607118, 607 9

Abstract:

An implantable device for providing electrical stimulation of cervical vagus nerves for treatment of chronic cardiac dysfunction with leadless heart rate monitoring 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. Finally, the neurostimulator includes an integrated leadless heart rate sensor configured to sense heart rate and to record the sensed heart rate as data into a memory.

An implantable device for facilitating control of 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. Finally, the neurostimulator includes a programmable switch configured to alter the triggering of the bi-directional action potentials in response to a magnetic signal received from outside the housing.

Abstract:

A computer-implemented system and method for selecting therapy profiles of electrical stimulation of cervical vagus nerves for treatment of chronic cardiac dysfunction is provided. An external programmer includes a plurality of therapy profiles stored in memory. The therapy profiles include different sets of stimulation parameters that cooperatively define alternating cycles of stimuli application and stimuli inhibition for a neurostimulator that are tuned to both efferently activate the heart's intrinsic nervous system and afferently activate the patient's central reflexes. A programming wand is configured to provide the set of stimulation parameters chosen by the user to the neurostimulator through wireless telemetry. Finally, an implantable neurostimulator device includes a stimulation therapy lead terminated by helical electrodes and electrically coupled to the neurostimulator. The implantable neurostimulator is configured to therapeutically stimulate the cervical vagus nerve through the helical electrodes by triggering bi-directional action potentials as specified by the selected set of stimulation parameters.
