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.
- fiber optic sensor
- Any device in which variations in the transmitted power or the rate of transmission of light in optical fiber are the means of measurement or control. Fibers can be used to measure temperature, pressure, strain, voltage, current, liquid level, rotation and particle velocity.
