The Catheter Guidewire Friction Tester is designed to accurately measure the frictional forces between catheters and guidewires. It is a critical tool for medical research and surgical practice, helping clinicians and engineers understand the movement behavior of guidewires and catheters within the human body. The device provides reliable data to optimize surgical procedures, improve catheter design, and enhance patient treatment outcomes.
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.
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:
