title: Comparative analysis for evaluating the traceability of interventional devices using blood vessel phantom models made of PVA-H or silicone.
abstract: OBJECTIVE
  In this paper, we investigated the parameters with effective traceability to assess the mechanical properties of interventional devices.
  
  
  METHODS
  In our evaluation system, a box-shaped poly (vinyl alcohol) hydrogel (PVA-H) and silicone were prepared with realistic geometry, and the measurement and evaluation of traceability were carried out on devices using load hand force. The phantom models had a total of five curve pathways to reach the aneurysm sac.
  
  
  RESULTS
  Traceability depends on the performance of the interventional devices in order to pass through the curved part of the model simulation track. The traceability of the guide wire was found to be much better than that of the balloon and stent loading catheter, as it reached the aneurysm sac in both phantom models.
  
  
  CONCLUSIONS
  Observation using the video record is another advantage of our system, because the high transparency of the materials with silicone and PVA-H can allow visualization of the inside of an artery.
