Abstract
A device for explanting an electrode device, particularly an intravascular or intracardiac electrode device having an electrode cable and an electrode head arranged on the cable's distal end, is capable of simply and safely detaching fibrotic matter from the entire surface of the electrode cable and electrode head. The explanting device has a stiff first sleeve, relatively short in relation to the length of the electrode cable, and whose diameter is slightly larger than the external diameter of the electrode cable. One end of the sleeve forms a cutting edge. The first sleeve is connected at its end opposite the cutting edge to a first control body in the form of a stylet with which the first sleeve can be moved along the implanted electrode device. A second sleeve, operable with another stylet, amy additionally be employed, having resilient cutting elements. The second sleeve can be slid over and past the first sleeve, causing its cutting elements to move toward each other for cutting fibrotic tissue around the top of the electrode head.
