Abstract
A cardiac lead has an electrode and fixation assembly including a plurality of fixation members movable to extended positions into heart tissue to retain the electrode in intimate engagement with heart tissue. An elongated stylet is used to move the fixation members to their extended positions into the heart tissue and retract the fixation members into the fixation assembly to allow the lead to be removed from the heart and body of a person.
