ABSTRACT:
The invention relates to a method and apparatus for extracting a pacemaker electrode whose electrode head has become embedded in the heart. An extractor including an elongated hollow shell, a wire which is located therein and which is movable relative to the shell, and an extractor head attached to the end of the wire. The extractor head includes spreadable barbs, the free ends of which can be spread out radially outwardly to hook into the wall of the lead of the embedded electrode. The extractor head is inserted into a lumen of a pacemaker electrode lead. When the wire is pulled the barbs will hook into the lumen wall. A handle is attached to the other end of the wire for exerting a pulling force on the electrode lead and the electrode when it has become firmly engaged with the umbrella head whereby the electrode will be dislodged from the heart.
