Electrical contacts on a medical device patch

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

a housing;

an electronics portion disposed within the housing, the electronics portion including at least one coil of electrically conductive material, the at least one coil configured to facilitate wireless power transfer to an implant located at the location within the subject to modulate the branched fibers of a hypoglossal nerve, the at least one coil having a plurality of windings; and

a mechanical connector associated with the housing configured to retain a flexible carrier and permit the housing to rotate relative to the flexible carrier, the flexible carrier including an adhesive and being configured for attachment to skin of the subject.

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 connector includes a pair of electrical contacts arranged substantially equidistant from a center of the housing.

5. The device of claim 1 , wherein the at least one electrical connector includes a plurality of connectors in electrical communication with the electronics portion.

6. The device of claim 1 further comprising at least one electrical connector associated with the housing in a manner permitting electrical connection to be maintained between the housing and the flexible carrier as the housing is rotated.

7. The device of claim 6 , wherein the electrical connector is configured to maintain a connection between the electronics portion and a battery associated with the flexible carrier.

8. A device for conveying power from a location external to a subject to a location within the subject, the device comprising:

a flexible carrier including a receiver, the flexible carrier being shaped to facilitate placement at the location external to the subject, the location external to the subject being between a chin and a neck of the subject and adjacent to the location within the subject, and wherein the location within the subject includes branched fibers of a hypoglossal nerve;

at least one coil of electrically conductive material located within a housing and configured to facilitate power transfer to an implant located at the location within the subject to modulate the branched fibers of the hypoglossal nerve, the at least one coil having a plurality of windings; and

wherein the housing includes a mechanical connector configured to mate with the receiver and permit the housing to rotate relative to the flexible carrier.

9. The device of claim 8 , wherein the flexible carrier further includes an electrical portion, the electrical portion configured to maintain electrical contact with at least one electrical connector associated with the housing as the housing is rotated.

10. The device of claim 9 , wherein the electrical portion includes conductive material arranged in a discontinuous circle.

11. The device of claim 10 , wherein the electrical connector includes a pair of electrical contacts arranged substantially equidistant from a center of the housing.

12. The device of claim 11 , wherein the distance of the electrical contacts from the center of the housing is substantially equal to a radius of the electrical portion.

13. The device of claim 9 , wherein the electrical portion includes a pattern of discontinuous conductive material arranged on the flexible carrier.

14. The device of claim 9 , wherein the flexible carrier further includes a battery.

15. A device for 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 branched fibers of a hypoglossal nerve, the flexible carrier;

an adhesive on a first side of the carrier;

at least one coil of electrically conductive material located within a housing and configured to facilitate power transfer to an implant located at the location within the subject to modulate the branched fibers of the hypoglossal nerve, the at least one coil having a plurality of windings; and

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