Title:
DC BLOCKING CIRCUIT AND EMBEDDING APPARATUS USING THE SAME
Document Type and Number:
Japanese Patent JPS60156458
Kind Code:
A
Abstract:
A direct current blocking circuit (18) adapted for use with an electrical load (14). First (12) and second (20) blocking devices are coupled in series with each other and in series with the electrical load (14) for substantially blocking the passage of direct current through the load (14). A shunt device (22) is coupled in parallel with the load (14) and coupled between the first (12) and second (20) blocking devices for shunting a portion of the direct current leaking through the first blocking device (12). In this manner. the load (14) is protected against the passage of direct current not only by the first blocking device (12) and the second blocking device (20) but also by the limited voltage appearing across the shunt device (22). Also provided is an implantable device for stimulating body tissue which utilizes the DC blocking circuit (18) described above.
