Abstract

A sterilizable containment that includes an inner packaging and an outer packaging. The outer packaging encloses the inner packaging and includes at least two electric feedthroughs. The inner packaging includes at least two electric contacts, wherein each of the at least two electric contacts of the inner packaging matches one of the at least two electric feedthroughs of the outer packaging to provide an electric connection between a respective feedthrough and the corresponding contact when the inner and the outer packaging are closed. Each of the contacts of the inner packaging feed electrical charge from outside of the inner packaging to the inside of the inner packaging and vice versa. The inner packaging includes electrically conducting media that allows propagation of electrical charge between the contacts of the inner packaging and an implantable medical device included inside in a packaging when the containment is filled.

First claim

What is claimed is:

1. A sterilizable containment for an implantable medical device comprising:
an inner packaging; and,
an outer packaging that encloses said inner packaging;
wherein said outer packaging comprises at least two electric feedthroughs and,
wherein said inner packaging comprises
at least two electric contacts,
wherein each of the contact at least two electric contacts of the inner packaging match one of the feedthroughs of the outer packaging to provide an electric connection between a respective feedthrough and the corresponding contact when the inner packaging and the outer packaging are closed,
wherein each of the at least two electric contacts feed one or more of electrical charge and voltage drops from outside the inner packaging to inside of the inner package and vice versa; and,

an electrically conducting medium that allows one or more of propagation of electrical charge and application of a voltage delta between said at least two electric contacts of the inner packaging and an implantable medical device contained in said inner packaging.

2. The sterilizable containment according to claim 1 , wherein the electrically conducting medium is a fluid.

3. The sterilizable containment according to claim 1 , wherein the outer packaging further comprises four feedthroughs and the inner packaging further comprises four contacts.

4. The sterilizable containment according to claim 1 , wherein the four contacts of the inner packaging part of four inner feedthroughs that feed one or more of electrical charge and voltage differences from the outside of said inner packaging to the electrically conducting medium inside the inner packaging.

5. The sterilizable containment according to claim 1 , wherein said at least two electric feedthroughs are capacitors.

6. The sterilizable containment according to claim 1 , wherein the inner packaging further comprises a coupling device that capacitive coupes to a communication electrode of said implantable medical device inside the inner packaging.

7. The sterilizable containment according to claim 1 , wherein the inner packaging further comprises a tube or vial with at least one sealing cap.

8. The sterilizable containment according to claim 1 , wherein the inner packaging further comprises at least one protrusion to assist centering said implantable medical device within the inner packaging or to hold said implantable medical device within the inner packaging.

9. The sterilizable containment according to claim 1 , wherein alone or more of the at least two electric contacts or one or more of the at least two electric feedthroughs or both one or more of the at least two electric contacts and one or more of the at least two electric feedthroughs include spring contacts.

10. The sterilizable containment according to claim 1 , further comprising an implantable medical device within the inner packaging.

11. The sterilizable containment according to claim 10 , wherein the implantable medical device is an implantable leadless pacemaker.

12. The sterilizable containment according to claim 10 , wherein the implantable medical device communicates with an external device using galvanic or electric field based data communication.

13. The sterilizable containment according to claim 10 , wherein the implantable medical device is stored in shelf mode and is activated to an active mode prior to implantation.

14. The sterilizable containment according to claim 1 , wherein said containment with said implantable medical device is configured to be closed and sterilized, and wherein the implantable medical device within the containment that is closed is configured to be one or more of programmed and tested.

15. A method of communicating with an implantable medical device, said method comprising:
placing the implantable medical device into a containment,
wherein said containment comprises
an inner packaging; and,
an outer packaging that encloses said inner packaging;
wherein said outer packaging comprises at least two electric feedthroughs and,
wherein said inner packaging comprises
at least two electric contacts,
 wherein each of the at least two electric contacts of the inner packaging match one of the at least two electric feedthroughs of the outer packaging to provide an electric connection between a respective feedthrough and the corresponding contact when the inner packaging and the outer packaging are closed,
 wherein each of the at least two electric contacts feed one or more of electrical charge and voltage drops from outside the inner packaging to inside of the inner package and vice versa; and,
 an electrically conducting medium that allows one or more of propagation of electrical charge and application of a voltage delta between said at least two electric contacts of the inner package and an implantable medical device in said inner packaging;

closing the containment that includes the implantable medical device,
sterilizing the containment that includes the implantable medical device; and,
one or more of programming and testing the implantable medical device within the containment that is closed.
