CIRCA Scientific

CIRCA Scientific was funded in 2010 to innovate safe, accurate, and fast technologies for improved patient care. CIRCA’s S-CATH* and the CIRCA Temperature Monitoring System* address the problems associated with slow, single sensor, small surface area standard esophageal temperature probes and monitors, which are constructed with a single thermistor or thermocouple embedded inside a 3-5mm wide probe tip. These standard probes are used during a variety of procedures but are slow to respond to temperature changes and difficult to see under x-ray guidance.

For example, some temperature probes and monitors only display new temperatures 1 or 2 times every 2 seconds, and only cover a small 3-5mm wide area of the esophagus’s 10-20mm potential width.

CIRCA’s single-use radiopaque S-CATH includes 12 temperature sensors that continuously sense for new temperatures. In addition, the S-CATH deploys in a two-plane modified “S” configuration to cover up to an 18mm+ wide area of the esophagus and improves visualization under x-ray.

The re-usable CIRCA Temperature Monitoring System is a compact touch screen monitor that displays the individual temperature of each sensor 20-times-per-second. The monitor also simultaneously displays the warmest sensor on the probe. Temperatures are displayed in numerical and graphical formats and the clinician can set audible/visual warnings and alarms.
