Feedthrough for electrical connectors

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.
