S-CATH Esophageal Temperature Probe


Designed for the Unique Needs of the OR and EP Lab

During therapeutic procedures, esophageal temperatures can change quickly.  S-CATH provides faster, more accurate temperature detection to both HOT and COLD temperature changes. The probe deploys an array of 12 fully insulated, fast response temperature sensors on a uniquely designed soft, flexible, “S” shape providing Edge-to-Edge coverage.

Key Benefits

Response Time

An independent study of 198 applications in 10 patients, the S-CATH recognized an initial temperature rise of 0.2ºC 17 seconds faster than a single sensor probe.1

Edge to Edge Coverage

In the same study, 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

RF Antenna Effect

PEBAX coating electrically insulates temperature sensors so there is no bare metal exposure.

Lateral Positioning Problems

Linear and single sensor temperature probes, no matter how fast, are prone to far lateral positioning in the esophagus.
