These circular and mesh array shaped catheters are also probably years away from FDA approval. Like balloon catheters they can fit into a pulmonary vein opening and isolate the opening in two or more passes.
These catheters also offer ablation at specific poles to produce pin-point ablation of A-Fib spots in the heart. Currently none of the versions offer internal or external irrigation. (Most RF catheter ablation today uses open irrigation to cool the catheter tip, which allows more energy to be delivered without the limitation of overheating the catheter tip.) (posted 2011)
