Area of Science:

  • Vascular Surgery
  • Medical Simulation
  • Anatomical Modeling

Background:

  • Current endovascular simulation models lack realistic haptic feedback.
  • This limits training for complex procedures like those involving arterial calcification or stenosis.

Purpose of the Study:

  • To develop a realistic and reproducible perfused cadaver model for endovascular training.
  • To enhance device development and research under clinically relevant conditions.

Main Methods:

  • Utilized fresh frozen elderly male cadavers (age 50-80).
  • Dissected the entire arterial tree and established inflow/outflow systems.
  • Created aortic aneurysms and performed endovascular interventions, including stent grafts and EndoAnchors deployment.

Main Results:

  • Achieved continuous arterial flow with realistic back-bleeding and tactile feedback.
  • Successfully simulated endovascular procedures, including stent graft deployment and device testing.
  • Demonstrated realistic haptic feedback for guidewires and devices.

Conclusions:

  • The pressurized cadaver flow model realistically replicates advanced endovascular procedures with haptic feedback.
  • This novel human cadaver model is suitable for training and device development in clinical settings.
