Abstract

Implantable transponders comprising no ferromagnetic parts for use in medical implants are disclosed herein. Such transponders may assist in preventing interference of transponders with medical imaging technologies. Such transponders may optionally be of a small size, and may assist in collecting and transmitting data and information regarding implanted medical devices. Methods of using such transponders, readers for detecting such transponders, and methods for using such readers are also described.

Claims

1. A transponder, comprising:

a coil comprised of a wire, wherein

a length of the transponder measures between about 5 mm and about 30 mm;

a width of the transponder measures between about 2 mm and about 5 mm and is less than the length of the transponder;

the transponder does not include a ferromagnetic material; and

the wire is wound along the length of the transponder.

2. The transponder of claim 1, further comprising an integrated circuit chip coupled to the coil.

3. The transponder of claim 2, further comprising a capsule enclosing the coil and the integrated circuit chip coupled to the coil.

4. The transponder of claim 1, wherein a diameter of the coil is smaller than the length of the transponder and greater than the width of the transponder.

5. The transponder of claim 1, wherein the transponder is configured to send and/or receive information within a range of from about 1 inch to about 5 feet.

6. The transponder of claim 1, wherein the wire is an enameled copper wire.

7. The transponder of claim 6, wherein the wire is wound around a core comprising biocompatible poly-ether-ether-ketone (PEEK).

8. The transponder of claim 1, wherein the transponder is cylindrical.
