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 externally to a skin portion of a subject; and

an output port operably connected to the reservoir for transferring a material through, and in direct contact with, the skin portion of the subject to a second device placed on a second side of the skin portion of the subject.

2. The device of claim 1, wherein the output port is configured for transferring the material via at least one of iontophoresis, microjets, sonophoresis, or an ultra fine stream.

3. The device of claim 1, further comprising:

a second port for transferring material through the skin portion of the subject to the second device.

4. The device of claim 3, wherein the second port is operably connected to the reservoir for transferring the material through the skin portion of the subject to the second device.

5. The device of claim 3, wherein the second port is operably connected to a second reservoir for transferring a second material through the skin portion of the subject.

6. The device of claim 1, further comprising:

a receiver for receiving a signal from the second device.

7. The device of claim 6, 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.

8. The device of claim 6, wherein the signal comprises:

a signal regarding at least one of a need for the material, a need for a quantity of the material, a need for a type of the material, a location, cessation of a need for the material, a quantity of the material collected, or a ready condition for receiving the material.

9. The device of claim 1, further comprising:

a transmitter for transmitting a signal to the second device

10. The device of claim 9, wherein the signal comprises:

a signal regarding at least one of a location, a desire to transfer material, a readiness to transfer material, a characteristic of the 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.

11. The device of claim 1, further comprising:

a sensor for detecting an indicator of the location of the second device.

12. The device of claim 11, wherein the indicator of the location of the second device comprises:

a fiducial on the subject.

13. The device of claim 11, wherein the indicator of the location of the second device comprises:

a fiducial on the second device.
