Abstract

A system includes a first sterile medical device container. The first sterile medical device container is transparent to radiofrequency (RF) signals in a particular frequency range. The system also includes a sterile medical device within the first sterile medical device container. The sterile medical device is capable of radiofrequency communication through the first sterile medical device container using the particular frequency range. The system further includes a second container fully enclosing the first sterile medical device container and the sterile medical device, the second container including RF shielding material that is substantially opaque to the RF signals in the particular frequency range.

First claim

What is claimed is:

1. A system comprising:
a first sterile medical device container having a plurality of compartments, wherein the first sterile medical device container is transparent to radiofrequency signals in a particular frequency range;
a sterile medical device within the first sterile medical device container, wherein the sterile medical device is capable of radiofrequency communication through the first sterile medical device container using the particular frequency range; and
a second container fully enclosing the first sterile medical device container and the sterile medical device, the second container comprising a first nonconductive layer, a second nonconductive layer, and radiofrequency shielding material that is substantially opaque to the radiofrequency signals in the particular frequency range, the radiofrequency shielding material disposed between the first nonconductive layer and the second nonconductive layer;
wherein the sterile medical device is disposed within a first compartment of the plurality of compartments, and wherein a tool associated with a procedure for implanting the sterile medical device is disposed within a second compartment of the plurality of compartments.

2. The system of claim 1 , wherein the sterile medical device is an implantable medical device.

3. The system of claim 1 , wherein the sterile medical device includes a communication device.

4. The system of claim 1 , wherein the sterile medical device is configured to:
power on in response to receiving, from an interrogator, a radiofrequency interrogation signal included in the radiofrequency signals in the particular frequency range.

5. The system of claim 4 , wherein the sterile medical device is further configured to transmit a device identification to the interrogator in response to receiving the radiofrequency interrogation signal.

6. The system of claim 5 , wherein the sterile medical device does not receive the radiofrequency interrogation signal when fully enclosed by the second container, wherein after the second container is opened, the sterile medical device is able to receive the radiofrequency interrogation signal within the first sterile medical device container.

7. The system of claim 6 , wherein the interrogator is located in a sterile environment and the second container is located in a non-sterile environment.

8. The system of claim 1 , wherein the radiofrequency shielding material includes an electrically conductive material.

9. The system of claim 8 , wherein the radiofrequency shielding material includes a metallic foil.

10. The system of claim 1 , wherein at least one of the first nonconductive layer or the second nonconductive layer is made from a plant based material.

11. The system of claim 1 , wherein the radiofrequency shielding material is substantially opaque to a particular radiofrequency signal transmitted at 2.45 gigahertz.

12. The system of claim 1 , wherein each of the first nonconductive layer, the second nonconductive layer, and the radiofrequency shielding material fully enclose the first sterile medical device container and the sterile medical device.

13. A system comprising:
a first sterile medical device container having a plurality of compartments,
wherein the first sterile medical device container is transparent to radiofrequency signals in a particular frequency range;

a sterile medical device within the first sterile medical device container, wherein the sterile medical device is capable of radiofrequency communication through the first sterile medical device container using the particular frequency range; and
a second container fully enclosing the first sterile medical device container and the sterile medical device, the second container comprising a first nonconductive layer, a second nonconductive layer, and radiofrequency shielding material disposed between the first nonconductive layer and the second nonconductive layer, wherein the second container is configured to block radiofrequency signals in the particular frequency range from being received at the sterile medical device via the radiofrequency shielding material;
wherein the sterile medical device is disposed within a first compartment of the plurality of compartments, and wherein a tool associated with a procedure for implanting the sterile medical device is disposed within a second compartment of the plurality of compartments.

14. The system of claim 13 , wherein the sterile medical device includes an implantable vagus nerve stimulation device.

15. The system of claim 13 , wherein the sterile medical device includes a communication device.

16. The system of claim 13 , the radiofrequency shielding material is substantially opaque to a particular RF signal transmitted at 2.45 gigahertz.

17. The system of claim 13 , wherein at least one of the first nonconductive layer or the second nonconductive layer is made from polymer material.
