Verification Testing

Flow Loop

A flow loop test was performed using a 3D printed version of the final venous stent design and porcine blood. As hoped, the stent did not migrate during the test.


Spectrophotometry Testing

In addition, stainless steel was found to be a hemocompatible material when compared to positive and negative controls.


Over the past couple of months, the team has been working to optimize the venous stent design. To accomplish this, ANSYS was used to perform flow and mechanical tests that were used to optimize every aspect of the stent.


ANSYS Fluent Flow Testing

ANSYS Static Structural Compression Testing

Results from these tests were analyzed using a scoring method the team developed. Parameters that were optimized include:

  • Ring Shape
  • Ring Height
  • Connection Shape
  • Connection Length
  • Number of Connections
  • Strut Thickness
  • Strut Width

Finally, the team was able to determine the following design is optimized for use in treating May-Thurner Syndrome.
