1. A method of ablation of an atrium of a heart of a patient, comprising:
- selecting a first elongated ablation component carrying a longitudinally extending first means for delivery of ablation energy and a second elongated ablation component and movable relative to the first ablation component, wherein the first and second components are provided with means mounted to and extending along the first and second components for magnetically attracting the first and second ablation components toward one another along the length of the first means for delivery of ablation energy;
placing selected one of the first and second components along a first portion of tissue of the atrium on an external portion of the heart adjacent one or more pulmonary veins;
placing the other of the first and second components along a second portion of tissue of the atrium on an external portion of the heart adjacent the one or more pulmonary veins to allow the magnetically attracting means to draw the first and second components toward one another to compress the first and second portions of tissue therebetween, along the length of the first and second components; and
applying ablation energy.

Abstract
A method for ablation in which a portion of atrial tissue around the pulmonary veins of the heart is ablated by a first elongated ablation component and a second elongated ablation component movable relative to the first ablation component and having means for magnetically attracting the first and second components toward one another. The magnetic means draw the first and second components toward one another to compress the atrial tissue therebetween, along the length of the first and second components and thereby position the device for ablation of the tissue.
