摘要： Ablation instruments and methods are disclosed for ablating diseased tissue such as cardiac tissue. The ablation device can remotely apply ablative energy to biological tissue and comprises a flexible elongate member having a proximal end, a distal end and a longitudinal lumen extending therebetween. An energy emitting element is disposed within the longitudinal lumen of the flexible elongate member. The energy emitting element has a proximal end and a distal end for emitting energy along at least a portion of its length. The device is configured to emit a variable amount of energy along a length of the flexible elongate member. The method includes introducing the flexible elongate member into a predetermined tissue site to ablate a target tissue. The target tissue is ablated, coagulated or photochemically modulated without damaging surrounding tissue.

摘要： 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.
