Abstract

Disclosed embodiments enable apparatus and methodologies that are provided for three-dimensional construction of tissues in the body at locations internal to the body.

First claim

What is claimed:

1. An apparatus for assembling biomaterials in a body into or onto functional body parts, the apparatus comprising:
at least one coil structure external to the body that applies an electromagnetic field to the biomaterials in the body under imaging guidance, and
biomaterials,
wherein the biomaterials contain, or are near, magnetic materials in the body,
wherein the biomaterials are in the vicinity of the magnetic materials wherein the biomaterials are assembled, in part, using temporary diamagnetic propulsive focusing effect with transient applied magnetic field pulses.

2. The apparatus of claim 1 , further comprising a controller that is coupled to and controls the at least one coil structure to control the electromagnetic field created by the at least one coil structure to change in time.

3. The apparatus of claim 1 , wherein the electromagnetic field created is controlled by control unit to vary in space by controlling the magnetic field gradient.

4. The apparatus of claim 1 , wherein the biomaterials are assembled successively within the body under imaging guidance into a functional structure.

5. The apparatus of claim 1 , wherein the biomaterials are assembled, in part, using heating of magnetic materials with alternating magnetic fields.

6. The apparatus of claim 1 , wherein the biomaterials are assembled, in part, using magnetic attraction between magnetic materials in the body.

7. The apparatus of claim 1 , wherein the biomaterials are assembled, in part, using materials released by the biomaterials under the influence of an electromagnetic field emitted by at least one coil structure external to the body.

8. The apparatus of claim 1 , wherein the apparatus assembles the biomaterials into an assembled functional body part and the assembled functional body part delivers a substance in the body.

9. The apparatus of claim 1 , wherein the apparatus assembles the biomaterials into an assembled functional body part and the assembled functional body part provides structural support in the body.

10. The apparatus of claim 1 , wherein the apparatus assembles the biomaterials into an assembled functional body part and the assembled functional body part provides mechanical support in the body.

11. The apparatus of claim 1 , wherein the apparatus assembles the biomaterials into an assembled functional body part and the assembled functional body part provides sensorimotor function in the body.

12. A method for assembling biomaterials in a body into or onto functional body parts, the method comprising:
applying, via at least one coil structure external to the body, an electromagnetic field to the biomaterials in the body under imaging guidance,
wherein said biomaterials contain, or are near, magnetic materials in the body,
wherein the biomaterials are in the vicinity of the magnetic materials, and assembling the biomaterials, in part, using temporary diamagnetic propulsive focusing effect with transient applied magnetic field pulses.

13. The method of claim 12 , further comprising controlling the electromagnetic field created by the at least one coil structure to change over time.

14. The method of in claim 12 , further comprising assembling the biomaterials successively within the body under imaging guidance into a functional structure.

15. The method of claim 12 , further comprising assembling the biomaterials, in part, using heating of magnetic materials with alternating magnetic fields.

16. The method of claim 12 , further comprising assembling the biomaterials, in part, using magnetic attraction between magnetic materials in the body.

17. The method of claim 12 , wherein the biomaterials are assembled, in part, using materials released by the biomaterials under the influence of an electromagnetic field emitted by at least one coil structure external to the body.

18. The method of claim 12 , further comprising assembling the biomaterials into an assembled functional body part, wherein the assembled functional body part delivers a substance in the body.

19. The method of claim 12 , further comprising assembling the biomaterials into an assembled functional body part, wherein the assembled functional body part provides structural support in the body.

20. The method of claim 12 , further comprising assembling the biomaterials into an assembled functional body part, wherein the assembled functional body part provides mechanical support in the body.

21. The method of claim 12 , further comprising assembling the biomaterials into an assembled functional body part, wherein the assembled functional body part provides sensorimotor function in the body.
