The Estech COBRA Fusion™ 50 Surgical Ablation System combines intuitive, real-time TCRF (Temperature Controlled Radiofrequency) energy control with proprietary Versapolar technology. Versapolar™ energy delivery is the first of its kind—an adaptable and effective platform that can deliver both bipolar and monopolar energy so that surgeons can easily and efficiently create reproducible transmural lesions with more flexibility, confidence and control. Built on over 10 years of engineering experience, the COBRA Fusion incorporates a unique suction design that gently pulls tissue out of the path of circulating blood to eliminate the heat sink effect, during both bipolar and monopolar modalities. The COBRA Fusion 50 incorporates integrated pacing and sensing for Immediate conduction block testing upon completion of lesion sets.
