The LightningWire™ system combines a novel electrosurgical guidewire with a dedicated Activation Cable to simplify procedures using preferred transseptal introducers and existing electrosurgical generators — now FDA‑cleared to create an atrial septal defect in the heart, whereby various cardiovascular catheters are introduced.
