Abstract

A method may include placing a first device on a first side of a skin portion of a subject and transferring a material through the skin portion of the subject from the first device to a subdermal second device disposed on a second side of the skin portion of the subject.

Claims

1. A device, comprising:

a reservoir configured for placement subdermally to a skin portion of a subject;

an input port operably connected to the reservoir and configured to receive a liquid material transferred through, and in direct contact with, the skin portion of the subject from a first device placed on an external side of the skin portion of the subject;

a fiducial, the fiducial positioned to align an output port of the first device with the input port for transfer of the liquid material from the first device to the reservoir; and

a transmitter configured to transmit a signal from a subdermal location to the first device.

2. The device of claim 1, wherein the input port comprises:

at least one of a self-healing material, a self-sealing material, a viscous material, a porous material, a second liquid material, a wickable material, or a closable window.

3. The device of claim 1, wherein the input port comprises:

a first window for providing access to an antechamber of the second reservoir.

4. The device of claim 3, further comprising:

one or more second windows configured to provide access to one or more inner chambers of the second reservoir.

5. The device of claim 4, further comprising:

a motor configured to control an amount of opening of at least one of the first window or the one or more second windows.

6. The device of claim 1, further comprising:

a second port for receiving material transferred through the skin portion of the subject.

7. The device of claim 6, wherein the second port is operably connected to the reservoir and configured to receive the liquid material transferred through, and in direct contact with, the skin portion of the subject from the first device.

8. The device of claim 6, wherein the second port is operably connected to a second reservoir configured for placement subdermally to the skin portion of the subject, the second port configured to receive a second liquid material transferred through the skin portion of the subject.

9. The device of claim 1, wherein at least a portion of the reservoir is configured to rotate to assist in retaining the liquid material.

10. The device of claim 1, wherein the reservoir comprises:

at least a portion of one wall constructed to have an attraction to the liquid material.

11. The device of claim 1, wherein the reservoir comprises:

at least a portion of one wall constructed to have a disattraction to the liquid material.

12. The device of claim 1, wherein the fiducial comprises:

at least one of a fluorescent marker, a marker having an enhanced radio signature, a radio frequency identification tag, a radio opaque marker, a retroreflector, or an ultrasonic marker.

13. The device of claim 1, wherein the signal comprises:

at least one of an electrical current, an electrical field, a magnetic flux, an optical signal, a radio frequency identification, or an ultrasonic signal.

14. The device of claim 1, wherein the signal comprises:

a signal regarding a need for the liquid material.

15. The device of claim 1, wherein the signal comprises:

a signal regarding a need for a quantity of the liquid material.

16. The device of claim 1, wherein the signal comprises:

a signal regarding a need for a type of the liquid material.

17. The device of claim 1, wherein the signal comprises:

a signal regarding a quantity of the liquid material collected.

18. The device of claim 1, wherein the signal comprises:

a signal regarding a location of the input port.

19. The device of claim 1, wherein the signal comprises:

a signal regarding cessation of a need for the liquid material.

20. The device of claim 1, wherein the signal comprises:

a signal regarding a ready condition for receiving the liquid material.

21. The device of claim 1, further comprising:

a receiver configured to receive a signal from the first device.

22. The device of claim 1, wherein the signal from the first device comprises:

a signal regarding at least one of a desire to transfer material, a readiness to transfer material, a characteristic of the liquid material to be transferred, an amount of material available to be transferred, a time for transfer to commence, an amount of material to be transferred, a desire to stop transfer, or an acknowledgement that transfer is complete.
