Abstract:
1. An ablation system for an operator to treat a patient, said system comprising: an ablation catheter including a first carrier arm having ablation elements and a second carrier arm having ablation elements for delivering thermal ablative energy to tissue, said catheter comprising a flexible shaft with a proximal end and a distal end, each ablation element having an electrical, tissue contact portion configured to deliver thermal ablative energy to tissue, a thermal dissipation portion that is electrically isolated from the electrical portion and configured to dissipate heat from the electrical portion into circulating blood, and a fin projecting from the thermal dissipation portion; an interface unit providing energy to the ablation catheter; and the interface unit monitoring at least one parameter of the system and preventing energy delivered from exceeding a cumulative energy threshold value, the cumulative energy being calculated as a sum of energy delivered over time.
