Abstract:
1. A system for ablating internal heart tissue in an ablation pattern on a surface of the tissue within the heart, the system comprising: an ablation catheter including a proximal end and a distal end, the distal end including an ablating tip portion operative to allow selective ablation of tissue, and a guiding device engageable with the ablation catheter, the guiding device including a template wire having a proximal portion extending along a lengthwise axis, a template portion located distal to the proximal portion, and the template wire includes a tissue anchoring portion operable to engage with tissue proximate to the tissue to be ablated so as to temporarily anchor the guiding device relative to the tissue to be ablated, wherein the template portion extends laterally relative to the lengthwise axis and is generally shaped to correspond to at least a portion of the ablation pattern, and the template wire and the ablation catheter are respectively configured to allow the ablating tip portion to be guided and moved along the template portion to apply at least a portion of the ablation pattern.
