Implant sleep apnea treatment device including an antenna

摘要

A sleep apnea treatment device may include a flexible carrier configured to be implanted in a body of a subject. The device may also include at least one electrode disposed on the flexible carrier, the at least one electrode being configured to modulate nerve fibers of the subject. A flexible antenna may be disposed on the flexible carrier, the flexible antenna electrically connected to the at least one electrode in a manner permitting at least some energy received by the flexible antenna to be transferred to the at least one electrode. The flexible antenna may include: at least a first conductive trace arranged on a first side of the flexible carrier, the at least a first conductive trace defining at least a first elongated space between portions thereof; and at least a second conductive trace arranged on a second side of the flexible carrier, the at least a second conductive trace defining at least a second elongated space between portions thereof, wherein the at least a first conductive trace is at least partially offset from the at least a second conductive trace such that portions of the first conductive trace overly the at least a second elongated space and wherein portions of the second conductive trace underlay the at least a first elongated space.

1. An implantable sleep apnea device, comprising:
a flexible carrier configured to be implanted in a body of a subject; at least one electrode disposed on the flexible carrier, the at least one electrode being configured for location on genioglossus muscle tissue proximate to a hypoglossal nerve of the subject and further configured to modulate hypoglossal nerve fibers of the subject; a flexible antenna disposed on the flexible carrier, the flexible antenna being sized for location beneath skin proximate a tongue of the subject, the flexible antenna being electrically connected to the at least one electrode in a manner permitting at least some energy received by the flexible antenna to be transferred to the at least one electrode, the flexible antenna including: at least a first conductive trace arranged on a first side of the flexible carrier, the at least a first conductive trace defining at least a first elongated space between portions thereof; and at least a second conductive trace arranged on a second side of the flexible carrier, the at least a second conductive trace defining at least a second elongated space between portions thereof, wherein the at least a first conductive trace is at least partially offset from the at least a second conductive trace such that portions of the first conductive trace overly the at least a second elongated space and wherein portions of the second conductive trace underlay the at least a first elongated space.
