CIRCA Scientific’s CrossWise™ RF Transseptal Access System introduces a transformative approach to achieving left atrial access during electrophysiology procedures. Unlike conventional systems that often require multiple exchanges of wires and sheaths, CrossWise employs a zero-exchange, RF-enabled cannula designed for precise, stable navigation through the septal wall. This proprietary cannula-guided technology delivers controlled RF energy while preserving the cannula’s shape and position, even in challenging anatomies such as thickened or fibrotic septal tissue. The result is a cleaner, faster, and more controlled puncture, reducing the complexity of transseptal access procedures.

In clinical and bench-top settings, CrossWise has demonstrated exceptional performance, successfully achieving septal crossing in as little as 290 milliseconds. Its design eliminates unnecessary instrument exchanges, improving procedural efficiency and reducing the risk of septal misplacement or unintended vessel trauma. With expanded compatibility to FARADRIVE‡ and VIZIGO‡ sheaths, the system now supports a wide range of electrophysiology workflows, making it highly adaptable across hospital settings and use cases. Physicians have reported a greater sense of procedural confidence and control, highlighting the intuitive nature of the system.

The successful completion of the Limited Market Release validates CrossWise as a significant innovation in cardiac access technologies. As CIRCA Scientific prepares to scale commercial availability across the U.S., the system is well-positioned to elevate standards in safety, efficiency, and precision for left-heart interventions. By delivering a streamlined, physician-centric solution with broad compatibility, CrossWise represents a key advancement in supporting growing demands for reproducibility and excellence in electrophysiology care.
