Resonetics Announces Acquisition of FISO Technologies

Adds world-class fiber optic sensor solutions

Nashua, NH – November 9, 2021 – Resonetics announced today that it has acquired FISO Technologies Inc. (FISO), a leading developer and manufacturer of fiber optic sensors and signal conditioners, from Nova Metrix LLC. Founded in 1994, Quebec City-based FISO provides leading-edge fiber optic development capabilities and advanced manufacturing experience to support high-volume production of complex fiber optic products for the medical device and energy markets. FISO’s sensors provide reliable solutions for measuring parameters such as pressure, temperature, force, displacement, and position.

“We are excited to add FISO’s innovative fiber optic capabilities to provide our customers with improved access to another novel technology that’s already proven useful in several clinical applications” said Tom Burns, President and CEO of Resonetics. “FISO serves market leaders in interventional cardiology, critical care and women’s health and we believe the technology has broad application in other clinical areas”.

FISO sensors offer significant advantages over traditional solid-state technology:

  • Extremely small size, flexible and kink resistant; highly suitable for minimally invasive disposable devices
  • No electrical components (no interference with electrosurgical instruments and compatibility with MRI systems and RF-MW ablation devices)
  • High frequency response and instantaneous readout to avoid signal attenuation and improve detection of transients
  • Extremely accurate in situ measurements of any physiological event
  • Robotic manufacturing for superior quality and high production volumes

FISO is Resonetics’ ninth acquisition in the past five years and continues to build upon the company’s leading position in advanced engineering and manufacturing solutions for the life sciences.
