Abstract

An apparatus and method are provided for spatially-selective administration of actions by at least one device in the body using a transducer that is sensitive to a spatially-variant energy field imposed on the at least one device by a source external to a subject's body; and at least one component in the at least one device, wherein interaction of the transducer with the imposed spatially-variant energy field causes or enables at least one component in the at least one device to affect nearby tissues in the body.

First claim

What is claimed is:

1. A method for spatially-selective administration of actions by at least one device in the body, the method comprising:
imposing a spatially-variant energy field on the at least one device by a source external to a subject's body;
exposing a transducer that is sensitive to the spatially-variant energy field to the spatially-variant energy field to affect nearby tissues in the body; and
affecting the nearby tissues via a spatially-selective administration of action performed as a function of the spatially-variant energy field imposed.

2. The method of claim 1 , wherein the imposed spatially-variant energy field is an electromagnetic field.

3. The method of claim 1 , wherein the nearby tissues include neurons.

4. The method of claim 1 , wherein the nearby tissues are stimulated, inhibited, or heated.

5. The method of claim 1 , wherein the nearby tissues are damaged so that the tissues can no longer reproduce.

6. The method of claim 1 , wherein the nearby tissues are damaged so that the tissues can no longer survive.

7. The method of claim 1 , wherein the nearby tissues are affected so as to potentiate subsequent application of another modality affecting the tissues.

8. The method of claim 1 , wherein the effect on the nearby tissues is implemented through the application of electrical energy, application of magnetic energy, application of light, application of heat, or application of kinetic energy.

9. The method of claim 1 , wherein the effect on the nearby tissues is implemented through contortion of the at least one device or of a cell in proximity to or containing the at least one device.

10. The method of claim 1 , wherein the effect on the nearby tissues is implemented through the release of chemicals or other particulate matters.

11. The method of claim 1 , wherein the transducer harvests energy from an electromagnetic field imposed on the device by the source external to the subject's body.

12. The method of claim 1 , wherein the transducer triggers the release of energy from another component in the device that harvests energy from a source external to the body.

13. The method of claim 1 , wherein activation of the at least one device depends on its local milieu.

14. The method of claim 1 , wherein the at least one device is directed to one or more locations in the subject's body by application of a spatially-variant electromagnetic field imposed on the device by a source external to the body.

15. The method of claim 1 , wherein a location of the at least one device is transmitted to a sensor external to the body.

16. The method of claim 1 , wherein an activation state of the at least one device is transmitted to a sensor external to the body.

17. The method of claim 1 , wherein a location of the at least one device is transmitted to another at least one other device in the body.

18. The method of claim 1 , wherein an activation state of the at least one device is transmitted to another at least one other device in the body.
