Abstract

Implementations of the present disclosure may take the form of an implantable electronic device such as an implantable pulse generator for administering electrotherapy via an implantable medical lead configured to couple with the implantable pulse generator, or an implantable cardiac monitor. The implantable electronic device includes a housing, a header connector assembly and a sealing member. The header connector assembly includes a connector assembly and a header enclosing the connector assembly. The sealing member is sandwiched between the header connector assembly and the housing.

First claim

What is claimed is:

1. An implantable electronic device comprising:
a housing having a top surface;
a header connector assembly comprising a connector assembly and a header enclosing the connector assembly, the header connector assembly having a bottom surface; and
a sealing member formed into an elongated body having an inner surface, the sealing member insertable between the header connector assembly and the housing, the elongated body of the sealing member extending along a peripheral boundary of an area interfacing between the header connector assembly and the housing, an assembly of the housing, the header connector assembly, and the sealing member creating a backfill volume defined by the top surface of the housing, the bottom surface of the header connector assembly, and the inner surface of the elongated body.

2. The implantable electronic device of claim 1 , wherein the header connector assembly comprises a groove in which the sealing member at least partially resides when inserted between the header connector assembly and the housing.

3. The implantable electronic device of claim 2 , wherein the groove is defined in the header of the header connector assembly.

4. The implantable electronic device of claim 1 , wherein the top surface of the housing comprises a groove in which the sealing member at least partially resides when inserted between the header connector assembly and the housing.

5. The implantable electronic device of claim 1 , wherein the sealing member extends along the entirety of the peripheral boundary continuous and uninterrupted.

6. The implantable electronic device of claim 1 , further comprising a backfill material located in the backfill volume.

7. The implantable electronic device of claim 1 , wherein the header connector assembly comprises a peripheral rim including a groove in which sealing member resides.

8. The implantable electronic device of claim 1 , wherein the housing comprises a peripheral rim including a groove in which sealing member resides.

9. The implantable electronic device of claim 1 , wherein the sealing member comprises at least one of a scone elastomer, a thermoplastic, elastomer, or a solvent based adhesive.

10. The implantable device of claim 1 , wherein the implantable electronic device comprises an implantable pulse generator for administering electrotherapy via an implantable medical lead configured to couple with the implantable pulse generator.

11. The implantable device of claim 1 , wherein the implantable electronic device comprises an implantable cardiac monitor.

12. A method of manufacturing an implantable electronic device, the method comprising:
a) sandwiching a sealing member having an elongated body between a housing and a header connector assembly, the elongated body of the sealing member extending along a peripheral boundary of an area interfacing between the header connector assembly and the housing; and
b) backfilling between a top surface of the housing, a bottom surface of the header connector assembly, and an inner surface of the elongated body of the sealing member with a backfill material, the sealing member preventing leaking of the backfill material.

13. The method of claim 12 , further comprising and subsequent to step a) and prior to step b), welding components of a connector assembly of the header connector assembly to components of a feedthru of the housing.

14. The method of claim 12 , wherein the header connector assembly comprises a groove in which the sealing member at least partially resides when sandwiched between the header connector assembly and the housing.

15. The method of claim 12 , wherein a top surface of the housing comprises a groove in which the sealing member at least partially resides when sandwiched between the header connector assembly and the housing.

16. The method of claim 12 , wherein the header connector assembly is pre-manufactured prior to being used to sandwich the sealing member between the housing and header connector assembly.

17. The method of claim 12 , wherein the sealing member is a pre-manufactured part having the same geometry as a groove in which the sealing member is received prior to being sandwiched between the header connector assembly and the housing.

18. The method of claim 17 , wherein the sealing member comprises at least one of a silicone elastomer, a thermoplastic elastomer, or a solvent based adhesive.

19. The method of claim 12 , wherein the sealing member is deposited into a groove as a silicone rubber based liquid or gel, the groove being part of at least the header connector assembly or the housing, the scone based liquid or gel being fully cured before the sealing member is sandwiched between the header connector assembly and the housing.

20. The method of claim 12 , wherein the sealing member is deposited into a groove as a silicone rubber based liquid or gel, the groove being part of at least the header connector assembly or the housing, the silicone based liquid or gel not yet being fully cured before the sealing member is sandwiched between the header connector assembly and the housing.

21. The method of cam 12 , wherein the sealing member is deposited into a groove as a solvent based adhesive, the groove being part of at least the header connector assembly or the housing, the solvent based adhesive not yet being fully cured before the sealing member is sandwiched between the header connector assembly and the housing.

22. The method of claim 12 , wherein the implantable electronic device comprises an implantable pulse generator for administering electrotherapy via an implantable medical lead configured to couple with the implantable pulse generator.

23. The method of claim 12 , wherein the implantable electronic device comprises an implantable cardiac monitor.
