Exergen Global's Temperature Sensor Ensures Safety, Efficiency for Ablation System

Exergen Non-Contact Sensor Plays Key Role in NeuWave Medical's Certus® 140 Cooling System

WATERTOWN, Mass., and ZIJTAART, the Netherlands, February 18, 2015 - Exergen Global today announced that its micro IRt/c.SV infrared, non-contact sensor plays a crucial role in maintaining consistent probe temperature for the NeuWave Certus® 140 2.45 GHz Ablation System. The Certus® 140, a soft-tissue ablation system, employs CO2 cylinders to ensure the probe shaft remains cool when delivering microwave energy to the target lesion. A temperature sensor plays a critical part in the Cooling System by measuring the CO2 tank’s temperature to gauge its capacity and ensure sufficient pressure during procedures. The CO2 in the Certus® 140 Cooling System also enables Tissu-LocTM, a process when engaged produces an ice ball that serves to secure the probe to the tissue during placement, reducing the risk of probe migration.

The Certus® 140 Cooling System, along with other customizable Certus® 140 platform components, sits on a compact, portable cart necessitating the development of a small-sized, non-contact temperature sensor to fit within the space limitations. With a size of just ¼” diameter and 1.47” long, the Exergen side view non-contact micro IRt/c.SV can be mounted vertically and integrated securely and unobtrusively, making it ideally suited for the cart. Since it is a non-contact sensor, its location on the cart remains constant, eliminating the risk of misaligning cylinders during replacement and ensuring an accurate and consistent temperature read. The sensor’s < 50 millisecond response time ensures no downtime in temperature detection following cylinder replacement.

“Exergen’s unparalleled experience developing unique sensor solutions made them the ideal partner to help us create a temperature sensor for the Certus 140 Cooling System,” said Rick Schefelker, Vice President of Engineering, NeuWave Medical. “We’ve been very pleased with its performance and results.”


“Through our medical market experience, we knew that the Certus 140 System temperature sensor needed to be both physician-friendly and cost-effective for healthcare organizations,” said Dr. Francesco Pompei, Founder and CEO of Exergen Corp. “We combined that experience with our deep knowledge of
thermal science and, working closely with the engineering team at NeuWave Medical, created an industry leading solution for the Certus 140 System.”

“The Certus 140 Cooling System demands a very small, rapid-response, non-contact sensor,” said Bram Stelt, Large Account Manager at Exergen Global. “Working with NeuWave Medical we were able to meet the company’s needs and integrate our sensor into the Certus 140 platform to ensure that their customers can easily replace cylinders without error.”
