Electrical contacts on a medical device patch
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.
1. A device for conveying power from a location external to a subject to a location within the subject, the device comprising:

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 opposing the location within the subject;
at least one coil of electrically conductive material, wherein the at least one coil includes a first coil of wire arranged on a first side of a dielectric carrier and a second coil of wire arranged on a second side of the dielectric carrier, the first coil of wire and the second coil of wire each having a plurality of windings; and
a housing including a mechanical connector configured to mate with the receiver and permit the housing to rotate relative to the flexible carrier, wherein the at least one coil of electrically conductive material is located within the housing and configured to facilitate power transfer to an implant located at the location within the subject to modulate at least one nerve.
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 adjacent to the location within the subject,
an adhesive on a first side of the carrier;
at least one coil of electrically conductive material located within the housing and configured to facilitate power transfer to an implant located at the location within the subject to modulate at least one nerve, wherein the at least one coil includes a first coil of wire arranged on a first side of a dielectric carrier and a second coil of wire arranged on a second side of the dielectric carrier, the first coil of wire and the second coil of wire each having a plurality of windings; and
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.
