A new radiographic technique precisely measures self-expanding stent forces and dimensions. This method accurately quantifies radial resistive force and chronic outward force during stent deformation.

Area of Science:

  • Biomedical Engineering
  • Materials Science
  • Radiology

Background:

  • Self-expanding stents are crucial in treating vascular diseases.
  • Accurate measurement of stent mechanical properties is vital for device design and clinical application.
  • Existing methods for measuring stent forces and dimensions can be limited.

Purpose of the Study:

  • To develop and validate a novel radiographic technique for measuring the radial resistive force, chronic outward force, and dimensions of self-expanding stents.
  • To assess the precision and accuracy of the developed measurement technique.

Main Methods:

  • A Mylar film and force gauge system was integrated with a micro-computed tomographic (CT) scanner.
  • Self-expanding nitinol stents were deformed within the micro-CT scanner.

  • Radial resistive force, chronic outward force, and stent dimensions were measured simultaneously during deformation.

    • Main Results:

    • The technique achieved high precision for force measurements (+/-3.3%) and dimension measurements (diameter precision <0.3%).
    • Stents exhibited significantly lower outward forces (1.2 N/cm) compared to compression forces (3.6 N/cm).
    • The study demonstrated the capability to obtain detailed stress-strain data for stents.

    Conclusions:

    • A precise radiographic technique for evaluating self-expanding stent mechanical properties has been successfully developed.
    • This method allows for accurate in-situ measurement of stent forces and dimensions during deformation.
    • The findings support improved stent design and performance evaluation.
