Abstract
A tissue ablation assembly (10) comprises an elongate probe device (14) , at least one ablation electrode element (16,18) carried by the probe device for conveying ablation energy, and at least one magnetic element (20) for substantially altering the path of the ablation energy conveyed by the electrode element (s) . In one embodiment, the magnetic element substantially urges the ablation energy radially outward. In another embodiment, magnetic element takes the form of a ring magnet that exhibits at least four alternating magnetic poles circumferentially disposed around the probe device axis .
