Abstract:
An ablation device for cardiac tissue, especially for forming a circular lesion in a vessel orifice (5) in the heart, comprisinga catheter (2) that is provided in the region of its distal end (3) with an abutment device (4) for holding the distal end (3) of the catheter (2) on a cardiac vessel orifice (5), and a linear ablation applicator (12) that is disposed distally in front of the abutment device (4) of the catheter (2) and can be brought from a straight passive position into a radially expanded, approximately circular-arc-type encircling ablation position, wherein the linear ablation applicator (12) is disposed distally in front of the abutment device (4) of the catheter (2) and is movably guided, at least in its distal end region, by means of a guiding sheath (10) adapted to slide from the distal end section (3) of the catheter (2) toward the abutment device (4) in such a way that through axial movement of the guiding sheath (10) in the proximal direction, the ablation applicator (12) can be brought into the ablation position.
