Controlled guided ablation treatment

摘要

An apparatus for forming a lesion in tissue along a desired ablation path includes a guide member having a tissue-opposing surface for placement against a heart surface. A guide carriage is sized to be received within the guide member and moveable along a longitudinal axis of the guide member. A tubular member extends from a proximal end of the carriage and out a proximal end of the guide member. An ablation element is carried in the carriage for movement. The ablation member is connected to a source of ablation energy through the tubular member. A sensor is provided for sensing a safety condition. The sensor is connected to a monitor external the guide member.
