ENGLEWOOD, Colo., March 3, 2022 /PRNewswire/ — CIRCA Scientific, Inc. today announced that its S-CATH™ M Esophageal Temperature Probe is now cleared for sale in United States. The new S-CATH M probe can be visualized on 3D cardiac mapping systems, which can help physicians reduce their reliance on fluoroscopy. It is the only commercially available multi-sensor esophageal temperature probe that provides high-density edge-to-edge coverage of the esophagus and is visible on 3D cardiac mapping systems.

Esophageal temperature probes can be used to alert physicians to critical changes in esophageal temperature that may occur during cardiac ablation procedures performed in the operating room (OR) or electrophysiology (EP) laboratory. However, many physicians currently rely on fluoroscopy to place, position, and reposition their esophageal temperature probe during a procedure. The use of fluoroscopy requires physicians and laboratory personnel to wear protective lead aprons to protect against radiation exposure.

The new S-CATH M has four electrodes that are placed on the centerline of the probe, allowing it to be placed, positioned and viewed on 3D mapping without relying solely on fluoroscopy.1 Additionally, S-CATH M features a proprietary micro-electrode design that limits the amount of exposed metal to what is absolutely necessary to be detected on 3D cardiac mapping systems, minimizing the possibilities for radio frequency (RF) interaction. . Research has shown that esophageal temperature probes with fully exposed metal electrodes can be inadvertently heated when used near the RF field.2-4

“We designed S-CATH M to support physicians’ efforts to minimize the amount of radiation their patients and staff are exposed to during their procedures without compromising the features that set our product portfolio apart,” said Lee Geist, President and CEO of CIRCA Scientific. “CIRCA Scientific is proud to join a growing community of medical device manufacturers responding to the demand for technology to reduce the use of fluoroscopy in OR and EP laboratories.”
