Abstract
A technique for removing from a body an implanted lead including an active fixation electrode includes the operation of releasably attaching an elongated stylet to the distal end of the implanted lead, specifically, to the electrode at the distal end of the lead. This results in a reasonably unified stylet and implanted lead structure whereby withdrawal of the stylet and of the implanted lead as a unit facilitates the complete removal of the implanted lead from the body. A threaded tip end of the stylet is used for threaded engagement with a tapped bore in the electrode. The threaded tip end of the stylet becomes locked to the electrode by rotating in one direction the threaded portion into the threaded bore and the stylet is removable by counter-rotating the threaded tip end of the stylet relative to the electrode.
