Feedthrough for electrical connectors
First Claim
1. A feedthrough for an implantable medical device comprising:
- an electrically insulating body including a first surface and a second surface; and
one or more electrically conductive structures configured to contiguously extend through and be embedded within said electrically insulating body, such that each of said one or more electrically conductive structures are circumferentially covered by said electrically insulating body, such that opposing ends of said at least one electrically conductive structures are exposed, and such that said at least one electrically conductive structures extend beyond at least the first or second surface,wherein the one or more electrically conductive structures comprise an electrically conductive metal or metal alloy and have a thickness of a film of the same electrically conductive metal or metal alloy.

Abstract
A method (10) of forming an electrically conducting feedthrough. The method (10) comprises a first step (11) of forming an electrically conductive structure (21) comprising a sacrificial component and a non-sacrificial component. At least a portion of the non-sacrificial component can then be coated with a relatively electrically insulating material (35) prior to removal of at least a portion of the sacrificial component from the electrically conductive structure. The structure of the feedthrough provides electrical connection through the wall of a housing of an implantable component while preventing unwanted transfer of materials between the interior of the component and the surrounding environment.
