Catheter Guidewire Friction Tester

Application

This tester is suitable for a wide range of medical devices and scenarios, including:

(1) Vascular catheters – assessing friction during navigation through blood vessels.

(2) Guidewires – evaluating smoothness and performance in different sizes and coatings.

(3) Interventional cardiology devices – testing guidewire-catheter interaction for stent delivery or balloon angioplasty.

(4) Neurovascular procedures – verifying low-friction performance for delicate cerebral interventions.

(5) Peripheral vascular interventions – assessing devices for minimally invasive surgery.

(6) R&D and quality control – optimizing material, coating, and design for improved surgical outcomes.

Standards

The instrument is designed to comply with the following standards:

(1) YY/T 1536-2017: Cardiovascular guidewire test method (China)

(2) ISO 11070: Sterile single-use intravascular catheters – Performance testing

Optional international standards for extended compliance:

(3) ISO 10555-1: Sterile single-use intravascular catheters – General requirements

(4) ASTM F2084: Guidewire mechanical performance testing

Features

(1) Measures friction force accurately between catheters and guidewires.

(2) High-precision force and displacement sensors capture real-time data.

(3) Stepless adjustable test speed to simulate different clinical scenarios.

(4) Adjustable chuck size accommodates a variety of catheter and guidewire diameters.

(5) Compact design suitable for laboratory and R&D use.

(6) Data acquisition system records force-displacement curves for analysis.
