Abstract

A device for conveying power from a location external to a subject to a location within the subject may include a flexible carrier and an adhesive on a first side of the carrier. A coil of electrically conductive material may be associated with the flexible carrier. A mechanical connector may be associated with the carrier opposite the adhesive, wherein the mechanical connector is configured to retain a housing and permit the housing to rotate relative to the flexible carrier. At least one electrical portion may be associated with the carrier in a manner permitting electrical connection to be maintained between the flexible carrier and the housing as the housing is rotated.

Claims

1. A device for treating sleep apnea by conveying power from a location external to a subject to a location within the subject, the device comprising:

a flexible carrier shaped to facilitate placement between a chin and a neck of the subject adjacent to an internal location of terminal fibers of a hypoglossal nerve;

an adhesive on a first side of the carrier;

at least one flexible coil of electrically conductive material located on the flexible carrier, the at least one flexible coil configured to facilitate power transfer to an implant located to modulate the terminal fibers of the hypoglossal nerve, the at least one coil having a plurality of windings;

a mechanical connector associated with the flexible carrier opposite the adhesive, wherein the mechanical connector is configured to detachably retain a housing including a power source and to permit the housing to rotate relative to the flexible carrier; and

at least one electrical portion associated with the flexible carrier in a manner permitting electrical connection to be maintained between the at least one flexible coil and the power source, as the housing is rotated, to enable powering the implant.

2. The device of claim 1, wherein the mechanical connector is configured to permit more than about 360-degree rotation of the housing relative to the flexible carrier.

3. The device of claim 1, wherein the mechanical connector is configured to permit rotation of less than about 360-degree rotation of the housing relative to the flexible carrier.

4. The device of claim 1, wherein the at least one electrical portion includes conductive material arranged in concentric rings.

5. The device of claim 1, wherein the at least one electrical portion includes a pattern of discontinuous conductive material arranged on the flexible carrier.

6. The device of claim 1, wherein the at least one electrical portion includes conductive material arranged in a plurality of arcs.

7. The device of claim 1, wherein the at least one flexible coil includes a first coil of electrically conductive material having a plurality of windings and a second coil of electrically conductive material having a plurality of windings, and wherein the first coil is arranged on the first side of the carrier between the adhesive and the flexible carrier and the second coil is arranged on the second side of the flexible carrier.

8. The device of claim 1, wherein the at least one flexible coil of electrically conductive material is elliptically shaped.

9. The device of claim 1, wherein the at least one flexible coil is further configured for use in transmitting power to an implant configured to modulate terminal fibers of the hypoglossal nerve.

11. The device of claim 1, wherein the at least one electrical portion includes a first electrical portion and a second electrical portion configured to enable electrical connection to be maintained between the flexible carrier and the housing as the housing is rotated.

10. A device for treating sleep apnea by conveying power from a location external to a subject to a location within the subject, the device comprising:

a flexible carrier shaped to facilitate placement between a chin and a neck of the subject adjacent to an internal location of terminal fibers of a hypoglossal nerve;

an adhesive on a first side of the carrier;

at least one flexible coil of electrically conductive material arranged on the flexible carrier, the at least one flexible coil configured to facilitate power transfer to an implant located to modulate the terminal fibers of the hypoglossal nerve, the at least one coil having a plurality of windings,

a mechanical connector associated with the carrier opposite the adhesive, wherein the mechanical connector is configured to retain a housing and permit the housing to rotate relative to the flexible carrier; and

at least one electrical portion associated with the carrier in a manner permitting electrical connection to be maintained between flexible carrier and the housing as the housing is rotated.
