Modulator apparatus configured for implantation

摘要

An implant unit according to some embodiments may include a flexible carrier, at least one pair of modulation electrodes on the flexible carrier, and at least one implantable circuit in electrical communication with the at least one pair of modulation electrodes. The at least one pair of modulation electrodes and the at least one circuit may be configured for implantation through derma on an underside of a subject's chin and for location proximate to terminal fibers of the medial branch of the subject's hypoglossal nerve, such that an electric field extending from the at least one pair of modulation electrodes can modulate one or more of the terminal fibers of the medial branch of the hypoglossal nerve.

主权项

1. A head pain management implant unit, comprising:
an elongated flexible carrier having a first end and a second end, the carrier being sized and configured for implantation beneath skin of a subject to extend from a first location of a substantially hairless region on one side of a hairline, across a hairline to a second location of a substantially haired region in a vicinity of an occipital nerve; an antenna located on the first end of the carrier for implantation in the first location; at least one pair of modulation electrodes located on the second end of the carrier for implantation in the second location; and at least one circuit in electrical communication with the at least one pair of modulation electrodes; wherein the implantable circuit and the at least one pair of modulation electrodes are configured to cooperate in order to generate an electric field adapted to cause modulation of at least a portion of the occipital nerve through application of an electric field.
