Abstract
An implantable medical lead for coupling to an implantable pulse generator may be configured for improved safety. The lead may include: a first electrode; a second electrode in electrical communication with the first electrode; and an active circuit element in electrical communication with the first electrode and the second electrode. The active circuit element may be configured to change an impedance of the lead. The active circuit element may be configured to change the impedance of the lead in response to a pacing signal or a signal having opposite polarity to a pacing signal. A method of using an implantable medical lead for improved safety may include changing an impedance of an implantable medical lead from a relatively high impedance to a relatively low impedance and/or changing an impedance of an implantable medical lead from a relatively low impedance to a relatively high impedance.
