FISO Technologies Launches the Smallest Commercially-Available Fiber Optic Pressure Sensor for the Medical Market


QUEBEC, Quebec - October 24, 2008 - FISO Technologies Inc., a subsidiary of Roctest Ltd (TSX: RTT) and a leading manufacturer of high-quality fiber optic sensors and measurement systems for challenging and demanding applications, announces the production release of the FOP-M260, the smallest commercially-available fiber optic pressure sensor and the first one below the size of a 1 French catheter. This new sensor, based on MOMS technology, has a diameter of 260 microns (0.010 inches) and accounts for a 50% size reduction over the current FOP-MIV pressure sensor. The development of this sensor is a significant step and provides an immediate solution to situations where the FOP-MIV size was a limitation. The sensor was officially launched at the Medical Design & Manufacturing "MD&M" exposition, which was held last October 22-23 at the Minneapolis Convention Center, Minneapolis, MN.

The FOP-M260 sensor shows better thermal performance and better stability than previous generations. Similarly to the previous fiber optic pressure sensors designed for the medical market, the FOP-M260 is compatible with FISO's EVOLUTION product line. By using the White-Light Fabry-Perot Interferometry technology, which has been deployed for more than a decade in challenging applications such as aerospace & defense, medical and process control, FISO customers are assured of accurate and reliable measurements in all field conditions.

"FISO is a unique reference for the medical market, where its sensors are integrated into medical devices. Combined with the FOP-MIV and the soon commercially-available FOP-F125, the FOP-M260 fiber optic miniature pressure sensor is part of the most extensive offer in the market", said Maxim Vachon-Savary, Product Line Manager at FISO Technologies. "The design of the FOP-M260 is similar to the FOP-MIV and will be easily integrated into FISO automatic assembly line, allowing FISO to reach the same high volume than the FOP-MIV, representing tens of thousands of units per year."
