CIRCA Scientific

CIRCA Scientific, Inc. is a company specializing in advanced esophageal temperature monitoring solutions for cardiac procedures. The company's primary product offerings include esophageal temperature probes designed to alert physicians to critical temperature changes during cardiac ablation procedures in operating rooms and electrophysiology labs. CIRCA Scientific's flagship product, the S-CATH M Esophageal Temperature Probe, received FDA clearance in March 2022. This multi-sensor probe provides high-density, edge-to-edge coverage of the esophagus and is visible on 3D cardiac mapping systems, potentially reducing the need for fluoroscopy during procedures.

In addition to the S-CATH M, CIRCA Scientific has developed the MATRIX12M Esophageal Temperature Probe, which offers improved temperature response compared to other probes on the market. The MATRIX12M provides 3x faster response than the S-CATH-M multi-sensor probe and 25 times faster response than common single sensor probes. CIRCA Scientific has also expanded its product line to include the CardioCurve Steerable Transseptal Sheath, which features a unique dual actuator system and improved sheath to dilator transition for cardiac access procedures.

The company's technology aims to help physicians avoid excessive heating or cooling of the esophagus during therapeutic procedures. CIRCA Scientific's esophageal temperature probes are designed with safety features, such as proprietary micro-electrode designs that minimize the risk of radiofrequency interaction. As of April 2024, the company reported supporting over 400,000 atrial fibrillation procedures in the previous decade, demonstrating its significant presence in the cardiac electrophysiology market.
