Abstract

An assembly of preformed curved enamel-coated ablative tipped endocardial electrodes are housed inside an outer sheath in a preformed geometric arrangement for insertion into heart chambers and application onto the endocardial surface of the heart. The position of the electrodes relative to each other is predetermined by their arrangement on a Teflon bushing which serves as a platform anchored on the end of an inner sheath. The inner sheath is moveable relative to the outer sheath thus allowing graded exposure of the electrodes controlling movement toward the apical and lateral walls of the chamber. Ablative energy is delivered through the 8 mm J-tipped electrode to destroy the arrhythmia focus or reentrant circuit.
