Overview

At a Glance

The product consists of a pressure guidewire, torque handle, and handle fiber-cable assembly. The length marks in the figure clarify the distal flexible section, access reference markers, and connection lengths.

3 cmDistal radiopaque spring tip

35 cmLaser-cut segment after the spring tip

38 cmTotal distal flexible section

90 cmRadial access marker from the distal end

100 cmFemoral access marker from the distal end

The pressure guidewire effective length is 180 ± 9 cm and the handle fiber-cable assembly is 190 ± 9 cm; the 90 cm and 100 cm markers are measured from the distal end.

Distal Structure

The distal structure is organized around access, radiopaque identification, and pressure capture. The tip includes core wire, stranded wire, and spring; the sensor is 3 cm from the distal end and the observation window is located at the spring-tip starting position.

1Core wire

Central element providing distal support and the basis for shaping.

28-strand wire

Stranded structure supporting torque transmission and distal stability.

3Spring

Half-section view showing the relationship between the core, stranded wire, and outer spring.

4Sensor observation window

The through-opening is the sensor observation window; the sensor is positioned 3 cm from the distal end.

Optical Sensing

Sensor Principle and EMC Advantages

External pressure acts on the pressure membrane and changes the Fabry-Perot cavity length. The reflected optical signal is demodulated into a pressure reading.

Working Advantages

EMCOptical signal chain

Optical signal transmission is insensitive to electromagnetic interference and supports signal stability in medical electrical environments.

MicroMiniature integration

Suitable for integration with the distal structure of a 0.014 in guidewire.

SignalDistal pressure capture

Pressure is captured at the distal end, reducing risks associated with long-distance electrical signal transmission.

EMC performance should be interpreted according to product validation, the applicable environment, and official technical documentation.

Pre-use Information

Recommended pre-use checks for external materials, product manuals, and distributor communication.

Intended useCoronary functional assessment

For distal/proximal pressure relationship measurement and FFR functional assessment.
