Temperature Monitoring
CIRCA Scientific’s portfolio of Esophageal Temperature Monitoring Products quickly and accurately alert you to critical esophageal temperature changes in time to respond. Featuring proprietary designs that deploy twelve rapid-response temperature sensors throughout the length and width of the esophagus, every CIRCA Scientific Esophageal Temperature Probe is built to provide best-in-class speed and coverage so temperature changes that matter don't go missed.

Matrix12™ M Esophageal Temperature Probe
Comprehensive coverage. Unprecedented speed. Expanded visualization on 3D cardiac mapping systems.
The GaplessGrid™ flex-circuit provides unique visibility on 3D cardiac mapping systems displaying up to 18mm in width with the fastest temperature response time and broadest coverage in the industry.

Unprecedented Speed
Thermally-responsive, super thin copper GaplessGrid flex-circuit contains 12 surface mounted thermistors providing near-real-time detection of temperature changes.
Expanded 3D Visualization
With four electrodes positioned on the outer legs of its GaplessGrid flex-circuit, MATRIX12 M displays up to 18mm in width.
Comprehensive Esophageal Coverage
Patented GaplessGrid flex-circuit provides the broadest esophageal coverage for procedural confidence over the entire target area.
S-CATH™ Esophageal Temperature Probe
During therapeutic procedures, esophageal temperatures can change quickly. S-CATH provides faster, more accurate temperature detection to both HOT and COLD temperature changes.

12 Sensors. Intelligently Positioned
12 electrically insulated, coated, fast response temperature sensors on a uniquely designed soft, flexible, “S” shape.
Edge-to-Edge Coverage
An independent study of 198 applications in 10 patients, a temperature rise of >2.0°C was recorded 40 times by the S-CATH. Single sensor probes missed 90% of those temperature rises.¹
Rapid Temperature Detection
In the same study, the S-CATH recognized an initial temperature rise of 0.2ºC 17 seconds faster than a single sensor probe.¹
S-CATH™ M Esophageal Temperature Probe
Accuracy you can trust. Now visible on 3D cardiac mapping systems. S-CATH M is a rapid-response, multi-sensor esophageal temperature probe visible on 3D mapping systems and is designed to provide high-density, edge-to-edge coverage of the esophagus during therapeutic procedures performed in the OR and EP Lab.

Minimal Metal Exposure
Pebax insulation covers 75% of the electrode’s surface area, limiting the amount of exposed metal to only what is absolutely necessary to be detected on 3D cardiac mapping systems.
Visibility in Context
Visibility on impedance-based 3D cardiac mapping systems allows physicians to view the location of the esophageal probe in the context of nearby anatomical structures.
CIRCA Esophageal Temperature Monitoring System
The CIRCA Temperature Monitoring System is designed to provide fast response to HOT and COLD temperature changes. The monitor continuously displays the temperature data from CIRCA Esophageal Temperature Probes in both numerical and an easy-to-interpret graphical fashion. The monitor is designed with user-programmable warnings and alarms at both high and low temperatures. These alarms signal the user both audibly and visually.
