Abstract:
1. An implantable pulse generator comprising: a header including a lead connector block electrically coupled to a first conductor; a can coupled to the header and including a wall and an electronic component electrically coupled to a second conductor and housed within the wall; and a feedthru mounted in the wall and including a header side, a can side, an electrical insulating core, a printed circuit board (PCB), a chip capacitor, a ground circuit, and a power circuit; wherein the core includes a first surface and a second surface, the first surface of the core forming at least part of the header side; wherein the PCB includes a first surface and a second surface, the first surface of the PCB abutting against the second surface of the core, the second surface of the PCB forming at least part of the can side and including a first electrically conductive region, a second electrically conductive region, and a first electrically non-conductive region separating the first electrically conductive region from the second electrically conductive region; wherein the power circuit extends through the PCB and core from the second conductor to the first conductor and is electrically connected to the second electrically conductive region; wherein the chip capacitor includes a first electrical contact electrically connected to the first electrically conductive region and a second electrical contact electrically connected to the second electrically conductive region, the chip capacitor spanning across the first electrically non-conductive region; wherein at least a portion of the ground circuit extends along the first electrically conductive region and is electrically coupled to the wall; wherein the second surface of the PCB further includes a second electrically non-conductive region surrounded by portions of the first electrically conductive region; wherein the feedthru further includes a radio frequency (RF) circuit extending through the second electrically non-conductive region as the RF circuit extends through the PCB and core; wherein the feedthru further includes a shield abutting against the second surface of the PCB and enclosing the chip capacitor; and wherein the shield includes a member having a metalized surface, the RF circuit extending through the member.
