Implantable electronic device employing fused thermoplastic-conductor subassembly and method of manufacturing the subassembly and the device
Disclosed herein is an implantable electronic device. The device has a housing and a header connector assembly coupled to the housing. The header connector assembly has a connector assembly and a header enclosing the connector assembly. The connector assembly has a subassembly including an electrically conductive component at least partially residing within a first material that is provided about the electrically conductive component. The header has a second material that is provided about the connector assembly and the subassembly subsequent to the first material setting up about the electrically conductive component.
1. A method of manufacturing an implantable electronic device, the method comprising:
forming a fused thermoplastic-conductor subassembly by causing an electrically conductive component of a connector assembly of a header connector assembly to fuse to a thermoplastic; and
forming a header of the header connector assembly about the fused thermoplastic-conductor subassembly;
wherein the thermoplastic comprises at least two opposed portions and the electrically conductive component is sandwiched between the two opposed portions prior to the electrically conductive component being fused to the thermoplastic.
2. The method of claim 1 , wherein the fusing is brought about by melting the thermoplastic via at least one of inductive heating, Ohmic heating or laser heating of the electrically conductive component.
3. The method of claim 1 , wherein the thermoplastic comprises at least one of Tecothane, Pellethane, Bionate or Elasthane.
4. The method of claim 1 , wherein the electrically conductive component comprises at least one of a wire, ribbon, antenna, block, or ring.
5. The method of claim 1 , wherein the header is formed about the thermoplastic-conductor subassembly via at least one of a backfilling process, an overmolding process, an injection molding process, or a casting process.
6. The method of claim 1 , wherein the sandwiched opposed portions and electrically conductive component are compressed between pressure platens when the electrically conductive component is being fused to the thermoplastic.
7. The method of claim 1 , wherein the resulting implantable electronic device comprises an implantable pulse generator for administering electrotherapy via an implantable medical lead configured to couple with the implantable pulse generator.
8. The method of claim 1 , wherein the resulting implantable electronic device comprises an implantable cardiac monitor.
