ABSTRACT:
A method is disclosed for the fabrication of feedthrough devices that can transmit a single or plurality of electrical signal(s) to or from within a leak-tight (hermetic) chamber from or to the outside of said leak-tight (hermetic) chamber. The invention allows materials known to be well-tolerated within the human body such as alumina-oxide ceramic and platinum to be used as raw materials in the fabrication of body-compatible, single or multi-channel leak-tight (hermetic) feedthroughs.
