03 / Distal structure
Guidewire control. Distal pressure sensing.
From distal to proximal: a spring segment, opposing sensor windows, then a laser-cut hypotube. The section beyond the sensor is a slotted tube, distinct from the wound distal spring.

01
Distal spring segment
The radiopaque distal spring, internal core wire and stranded wire support shaping, visibility and torque transmission.
02
Opposing sensor windows
The sensor region follows the spring, with windows on opposite sides of the tube for pressure acquisition.
03
Laser-cut hypotube
A laser-cut hypotube follows the sensor region. Its surface slots are machined into the tube wall, not formed by a continuously wound spring.
04
Hydrophilic coating
A 35 cm distal hydrophilic coating supports intravascular passage and delivery.
04 / Optical sensing
Sensing principle & EMC advantages
Pressure-induced membrane movement changes the Fabry–Pérot cavity length. The system demodulates reflected light into pressure readings, while the optical signal path is less susceptible to electromagnetic interference.
How the sensor works

- 01
Pressure acts
Intravascular pressure causes a small deformation of the sensor membrane.
- 02
Light changes
Membrane displacement changes the FP cavity length and reflected spectrum.
- 03
The system reads
The pressure receiver and console demodulate the optical signal and display a pressure reading.
Working advantages in an EMC environment
The wire transmits pressure changes through optical fiber, without conductive signal cables, electrodes or electronic components inside the wire.
- 01FP sensor
- 02Fiber-optic cable
- 03Pressure receiver / console
- Electromagnetic interference resistance
- The optical signal path is insensitive to electromagnetic sources such as electrosurgical and fluoroscopy equipment.
- No electrical signal into the body
- The wire contains no conductive signal cables, electrodes or electronic components; no electrical energy is transmitted on the patient side.
- Defibrillation tolerance
- The fiber-optic cable has completed 360 J defibrillation-discharge tolerance verification.
05 / Before use
Key information before use
Confirm intended use, system compatibility, package integrity, shelf life, sterile single-use requirements and key restrictions.
Use & compatibility
- Intended use
- For intravascular pressure measurement in coronary and peripheral vessels.
- System compatibility
- For use only with the Enlightening FFR measurement system and pressure receiver.
- Measurement display
- The paired system displays Pa / Pd, pressure waveforms and FFR results.
Pre-use checks
- Package & shelf life
- Confirm that the package is intact and the product is within its 3-year shelf life.
- Sterile, single use
- Supplied sterile. Do not reuse, reprocess or resterilize.
- Key restrictions
- Not for neurovascular use. Protect the sensor region and fiber cable during handling.
Important
This is a sterile, single-use fiber-optic pressure guidewire. Check package integrity and expiry before use, connect the designated system and complete pressure equalization.
