Abstract:
1. An implantable medical device, comprising: a hermetic housing comprising a case and a cover, the case and the cover each having an interior surface; a piezoelectric transducer incorporated into a first flexible circuit mounted to the interior surface of the cover, the piezoelectric transducer having a first electrical contact; a hybrid circuit assembled in the case; means for electrically coupling the piezoelectric transducer to the hybrid circuit assembled in the case, the electrical coupling means comprising-an elongated flexible circuit having a normally planar geometry and comprising an extender portion extending between a proximal end attached to the first flexible circuit and a free distal end, a second electrical contact positioned along the extender free distal end and electrically coupled to the hybrid circuit, and a conductive trace extending along the extender portion from the second electrical contact and electrically coupled to the first electrical contact, the elongated flexible circuit expanding from its normally planar geometry to flexibly extend the second electrical contact away from the first flexible circuit when the cover is removed from the case while maintaining electrical coupling between the first electrical contact and the hybrid circuit, the elongated flexible circuit resuming the planar geometry upon closure of the case and the cover; and a second flexible circuit comprising an antenna, the second flexible circuit overlaying the hybrid circuit assembled in the case and having a third electrical contact formed on a top surface of the second flexible circuit, a conductive trace extending from the third electrical contact and electrically coupled to the hybrid circuit, the second electrical contact being electrically coupled directly to the third electrical contact, the piezoelectric transducer nesting within the antenna upon closure of the case and the cover.
