This course is part of Self-Expanding Stents Simulation Certification. Finish all the courses associated with the Simulation Certification to earn the digital credential.

Stents are commonly used in the treatment of various vessel disorders and vascular diseases, most notably coronary artery disease. While designing stents it is necessary to ensure their proper function and confirm that the stent opens the occluded vessel and withstands repetitive movements, all while preventing breakage and failure due to these various loading conditions.

In this course we will cover the detailed modeling of stents from geometric flat patterns to simulating the stent and making some preliminary design assessments regarding its performance. Our lessons will cover these eight main topics:

  • Introduction to Self Expanding Stents 
  • Geometric Representation 
  • Material Modeling 
  • Nitinol Characteristics 
  • Stent Expansion  
  • Stent Shape Setting 
  • Stent Crimping 
  • Preliminary Design Assessments 

Each video-based lecture is accompanied by a printable handout. Most lessons have a step-by-step video-based workshop to follow along in Ansys Mechanical.

There are three homework simulations examples:

  • Creating repeating patterns in a stent 
  • Expansion, shape setting, and crimp of a generic stent design 
  • Crimping of a stent using arc-shaped crimpers 

Finally, the course wraps up with a quiz. Let's get started.
