The system utilizes a proprietary electrosurgical guidewire paired with a dedicated activation cable, allowing surgeons to maintain control of radiofrequency energy directly from the sterile field. Despite a 0.032-inch diameter that ensures broad compatibility with standard transseptal introducers, the wire is engineered to be stiffer than market-leading 0.035-inch alternatives. This mechanical profile supports the delivery of bulky therapy devices for interventions such as atrial fibrillation ablation and mitral valve repair.

ElectroWire Medical Cleared for LightningWire Transseptal System
The U.S. Food and Drug Administration has granted 510(k) clearance to the LightningWire Transseptal Puncture System, a new electrosurgical tool designed to create atrial septal defects. Developed by Lexington-based ElectroWire Medical, the device aims to streamline complex cardiovascular procedures by integrating with existing hospital equipment.
Dr. James Stewart of Piedmont Atlanta’s Marcus Heart Valve Center noted that the device offers precise septal crossing while simplifying the delivery of equipment into the left side of the heart. From an economic perspective, Dr. William Brabham of Lexington Medical Center highlighted the potential for cost efficiency, suggesting the versatile platform could integrate seamlessly across various existing industry infrastructures. ElectroWire Medical, a startup founded by cardiologist Dr. Robert Leonardi, has initiated a limited market release of the technology as it continues its current capital-raising efforts.
