Abstract
(EN)
Apparatus for localising an electrical field for electroporation of tissue includes a pulsed DC electrical power supply and at least one catheter tip and electrode assembly configured for endocardial placement such that electrodes positionable at separate endocardial locations allow development of an electrical field between the electrodes to effect electroporation of tissue in the electrical field.
