MATRIX12 M Esophageal Temperature Probe

Comprehensive coverage. Unprecedented speed. Expanded visualization on 3D cardiac mapping systems.

New GaplessGridTM 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.

Comprehensive coverage. Unprecedented speed.

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.

Indications for Use

The CIRCA Temperature Monitoring System is composed of CIRCA Temperature Monitor and the CIRCA MATRIX12™ M
Probe and is intended for the continuous detection, measurement and visualization (in °C) of esophageal temperature.
The intended environments of use are operating rooms and interventional electrophysiology rooms. The CIRCA
Monitor must be used in conjunction with the CIRCA MATRIX12™ Probe.


The role of esophageal temperature monitoring using this device in reducing the risk of cardiac ablation-related
esophageal injury has not been established. The performance of the CIRCA MATRIX12™ M temperature probe in
detecting esophageal temperature changes as a result of energy delivery during cardiac ablation procedures has not been
evaluated.
