Methods and devices for directionally ablating tissue
First Claim
1. An ablation device for remotely applying ablative energy to biological tissue comprising:
- an elongate member having an inner lumen extending therethrough;
a positioning mechanism for slidably disposing an energy emitting element within the inner lumen of the elongate member and having a shape that is adapted to prevent rotation thereof within the inner lumen of the elongate member.

Abstract
Ablation instruments and methods are disclosed for ablating diseased tissue such as cardiac tissue. The method includes introducing a flexible elongate member into a predetermined tissue site with a flexible elongate member having a proximal end, a distal end and a longitudinal lumen extending therebetween. A slidable conductor is positioned through the lumen proximate to the tissue site and energy is transmitted to the distal end of the elongate member through the conductor. The flexible elongate member is both longitudinally flexible and resists twisting during bending. The target tissue is ablated, coagulated or photochemically modulated without damaging surrounding tissue.
