Feedthrough for electrical connectors
First Claim
1. A method of forming an electrically conducting feedthrough for implantable medical device comprising:
- forming an electrically conductive structure comprising a sacrificial component and a non-sacrificial component comprising at least one electrically conductive elongate member;
coating at least a portion of the non-sacrificial component with an electrically insulating material such that each said at least one electrically conductive elongate member is contiguous and circumferentially covered by said electrically insulating material hermetically sealing said at least one electrically conductive elongate member; and
removing at least a portion of the sacrificial component from the electrically conductive structure to expose opposing ends of said at least one electrically conductive elongate member; and
electrically coupling at least one opposing end of said at least one hermetically sealed and electrically conductive elongate member to the implantable medical device.

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.
