Patent ID: 8195308

Claim:
An implantable hermetically sealed structure dimensioned to be placed inside a lead, the structure comprising: an in vivo corrosion resistant holder comprising: a plurality of in vivo corrosion resistant walls (“walls”), each wall in the plurality of walls comprising a top edge, adjoining edges, and a bottom edge, each adjoining edge of each wall in the plurality of walls physically associated with a respective adjoining edge of a respective wall in the plurality of walls to form a first opening at one end and a second opening at an opposite end; a bottom physically associated with the bottom edge of each wall in the plurality of walls to cap the first opening at one end of the in vivo corrosion resistant holder; and at least one conductive feedthrough extending through the bottom; and a metallic sealing layer physically associated with the top edge of each wall in the plurality of walls to substantially cap the second opening at an opposite end and to define a volume capable of accommodating an effector, whereby the metallic sealing layer, the in vivo corrosion resistant holder, and the at least one conductive feedthrough in combination are operable to hermetically seal the effector.
