Your Pressure Guidewire to DIAGNOSE and TREAT with Confidence

2nd Generation Fiber Optic Sensor

OpSens OptoWire is a modern pressure guidewire designed to assess stenoses in vessels such as coronary arteries.

OptoWire is powered by Fidela™, a patented 2nd generation fiber optic sensor to measure physiologic indices including Fractional Flow Reserve (FFR and diastolic Pressure Ratio (dPR).

The large nitinol core from the OptoWire provides unique workhorse
performance by allowing unique control, torque and support while achieving great performance with consistent and repeatable measurements.

OpSens revolutionary technology makes disconnecting/reconnecting
the guidewire several times possible. It translates into the opportunity to
provide Percutaneous Coronary Intervention over the same guidewire without device exchange. It also allows making measurements pre-and post procedures.

The OptoWire provides the lowest drift in the industry1
and allows physicians to have confidence in their diagnosis and treat the most
complex anatomies with peace of mind. It brings efficiency by saving time,
adjunct devices, and costs.
