IMPLANTABLE DEFIBRILLATION OUTPUT CIRCUIT
First Claim
1. An implantable defibrillation circuit, comprising:
- an implantable output circuit including;
a first switch configured to controllably connect a first supply node to a first output node;
a second switch configured to controllably connect a second supply node to the first output node through a first rectifier;
wherein the second switch is configured to inhibit the first switch from connecting the first supply node to the first output node when the second supply node is connected to the first output node through the second switch; and
wherein the first output node is configured to be coupled to a first implantable electrode.

Abstract
An implantable defibrillation circuit can include an output circuit. The output circuit can include a first switch configured to controllably connect a first supply node to a first output node, a second switch configured to controllably connect a second supply node to the first output node through a first rectifier, and the second switch can be configured to inhibit the first switch from connecting the first supply node to the first output node when the second supply node is connected to the first output node through the second switch. In an example, the first and second switches can include insulated gate bipolar transistors.
