## 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

### Claim 1

An integrated port assembly comprising:
a chamber configured to receive a fluid;
wherein an inner surface of the chamber is formed from a material having a density, hardness, or thickness configured to prevent or resist puncturing by a fluid deposition device;
an electromagnetic wire coil having two ends, each end coupled to an application specific integrated circuit;
wherein the electromagnetic wire coil shares a central axis with the chamber; and
a port dome covering an opening of the chamber, the port dome configured to seal the chamber;
wherein the port dome is configured to be penetrable by the fluid deposition device and self-sealing upon removal of the fluid deposition device.

### Claim 2 (depends on 1)

The integrated port assembly of claim 1, wherein the application specific integrated circuit is configured to communicate with radio frequency signals.

### Claim 3 (depends on 1)

The integrated port assembly of claim 1, wherein a side of the chamber comprises at least one fluid exit hole.

### Claim 4 (depends on 1)

The integrated port assembly of claim 1, wherein the chamber includes at least one fluid entry hole and at least one fluid exit hole; and
wherein the electromagnetic wire coil and application specific integrated circuit are separated from the chamber by a fluid deposition device stopping surface.

### Claim 5 (depends on 1)

The integrated port assembly of claim 1, further comprising a valve assembly, the valve assembly formed from a non-ferromagnetic material.

### Claim 6 (depends on 1)

The integrated port assembly of claim 1, further including a transponder, the transponder including:
a capsule enclosing the electromagnetic wire coil and the application specific integrated circuit.

### Claim 7 (depends on 6)

The integrated port assembly of claim 6, wherein the transponder is configured to be located by an external reader.

### Claim 8 (depends on 1)

The integrated port assembly of claim 1, wherein the chamber is formed from at least one of poly-ether-ether-ketone, ceramic, silica glass, biocompatible plastic, or silicone.
