Opsens Inc.
Opsens Inc. of Quebec City has filed a patent application for
the OptoWire, a second diagnostic tool to assess coronary lesions by performing
fractional flow reserve measurement. The company’s in-house team has been
developing OptoWire in parallel with EasyWire, also used in fractional flow reserve.
The latter was unveiled in December 2010. The OptoWire is a guide wire with a fiber
optic pressure sensor that is drift-free and that provides high-fidelity measurement
of blood pressure in coronary arteries. It offers better mechanical performance
in terms of trackability, torquability and support over existing pressure guide
wires, according to the company.
