Abstract:
A tissue ablation system for ablating a region of tissue, comprising:an anchor device having an elongate body with a proximal end portion and a distal end portion that is adapted to be positioned within the pulmonary vein, and also having an expandable member along the distal end portion adjustable between a radially collapsed condition and a radially expanded condition that is adapted to engage the pulmonary vein; and an ablation device comprising an elongate catheter having a proximal region and a distal region, and an ablation element located along the distal region, the ablation element being adapted to form a substantially linear lesion along the region of tissue, wherein the ablation device is adapted to slideably engage and track over the anchor device, such that the ablation element can be ablatively coupled to the region of tissue by advancing the ablation device distally over the anchor device.
