Abstract

Methods and devices for hypodermic implanting micro-transponders into a body. The method includes preassembling an array of micro-transponders into a cannula which is configured for tissue penetration and injection.

Claims

1. A method for implanting a plurality of micro-transponders into a cellular matter, comprising the actions of:

pre-assembling a plurality of micro-transponders in a cannula to form a loaded-cannula wherein said cannula is configured to hold micro-transponder in a fixed orientation; and

ejecting said microtransponders from said cannula into the cellular matter, to thereby form extended array of microtransponders.

2. The method of claim 1, wherein said micro-transponders are smaller than 1 square millimeter.

3. The method of claim 1, wherein said loaded-cannula is sterilized and disposable after first use.

4. The method of claim 1, wherein said microtransponders are packaged in a biocompatible material made of Matrigel™

.

5. The method of claim 1, wherein the step of pre-assembling is performed during the manufacturing process.

6. The method of claim 1, wherein said micro-transponders form a spatially arranged array with other micro-transponders in said cannula during the step of pre-assembling.

7. The method of claim 1, wherein said micro-transponders forms a spatially arranged array with other micro-transponders in the cellular tissue after the step of ejecting.

8. The method of claim 1, wherein said micro-transponders are wirelessly and electro-magnetically connected to an external device.

9. The method of claim 1, wherein said cannula has a flat extrusion at the free end that guides said micro-transponders disposition in the cellular matter.

10-12. -12. (canceled)

13. A method for implanting micro-transponders into a cellular matter, comprising the actions of:

forming a plurality of micro-transponders to be a spatially arranged array;

embedding said array in a bio-compatible packaging material to form a strip;

loading said strip into a cannula; and

ejecting said strip into a cellular matter.

14. The method of claim 13, wherein said individual micro-transponders are smaller than 1 square millimeter.

15. The method of claim 13, wherein said loaded-cannula are sterilized and disposable after first use.

16. The method of claim 13, wherein said biocompatible material is made of SU8.

17. The method of claim 13, wherein the step of loading is performed during the manufacturing process.

18. The method of claim 13, wherein said micro-transponders are suspended in Matrigel™

before the step of forming an array.

19. The method of claim 13, wherein said micro-transponders are wirelessly and electro-magnetically connected to a device.

20-22. -22. (canceled)

24. A device for hypodermic micro-transponder delivery, comprising:

a) a cannula pre-loaded with a micro-transponder array of plurality of microtransponders; and

b) an ejection mechanism which is configured to push through said cannula;

wherein said cannula is configured for tissue penetration and injection.

25. The device of claim 24, wherein said cannula is configured to accommodate with the shape of said micro-transponder array.

26. The device of claim 24, wherein said cannula is configured such that its free end opening is shaped to guide the orientation of said microtransponder array during a hypodermic delivery.

27. The device of claim 24, wherein at least one said micro-transponder has a width less than 1 mm.
