Abstract:
1. A method, comprising: delivering defibrillation shock energy from an implantable shock therapy energy storage capacitor to a subject through an electrical circuit disposed on at least one of printed wiring board, a hybrid circuit board, or an integrated circuit device; in response to the delivered defibrillation shock energy exceeding a threshold, triggering a plasma switch to switch into shunting the defibrillation shock energy being delivered from the capacitor away from the electrical circuit and to at least one of a circuit power or ground node, including vaporizing material to form a cloud of vaporized material to form an electrical conduction path from the electrical circuit to the node, wherein the cloud is to bridge a nonconductive gap between the electrical circuit and the node, the gap having a dimension selected to be within the cloud of vaporized material.
