Abstract: Disclosed herein is an implantable pulse generator. The implantable pulse generator includes a header, a can, a feedthru, a feedthru substrate and a conductor. The header includes a lead connector block. The can is coupled to the header and includes a wall and an electronic substrate housed within the wall. The feedthru is mounted in the wall and includes a header side, a can side and a feedthru wire extending through the feedthru and having a first end and a second end opposite the first end. The first end is electrically coupled to the lead connector block. The feedthru substrate is adjacent the can side and includes capacitance layers, an electrically conductive input layer, and an electrically conductive input surface defined on a surface of the feedthru substrate and electrically coupled to the input layer. The input layer is electrically coupled to the second end. The conductor electrically couples the input surface and the electronic substrate. The conductor may be in the form of a wire bond.
