Abstract:
An ablation lead for treating atrial flutter, comprising:a lead body having proximal and distal ends; a screw tip adapted to be fixed in an apex of a right ventricle of a human heart, the screw tip being disposed at the distal end of the lead body; an array of electrodes for delivering RF energy, the electrodes and the screw tip being spaced apart from one another, and the electrodes being arranged on the lead body in such a manner, that when the screw tip is affixed In the apex of the right ventricle the electrodes can ablate a first area between the tricuspid annulus and the inferior vena cava of a human heart or a second area between the coronary sinus and the tricuspid annulus, the screw tip being configured to not dislodge from the apex of the right ventricle when the electrodes ablate the first or second areas, the screw tip being electrically isolated from the electrodes.
