Vascular disease is a major cause of death, therefore it is desirable to develop robots and simulation tools for catheter trajectory evaluation. Until now trajectory completion duration, catheter tip location, wall deformation, morphology and stress applied to blood vessel phantom wall were identified as evaluation parameters during endovascular surgery simulation. For that purpose image processing...
Silicone vasculature phantoms built relying on medical imaging data and computer assisted designed were presented in 2005 as an in-vitro simulation environment for endovascular surgery simulation. Due to the realistic recreation of human vasculature morphology and mechanical characteristics, several simulation techniques were created relying on that modeling technology to satisfy different simulation...
It is desirable for endovascular surgery simulation to describe with quantitative data the interaction between the catheter and the blood vessel model wall to make an objective evaluation of the procedure. Photoelastic stress analysis in straight segments of multi-layered models was used for that purpose. In this research we study the error introduced by stress direction on the magnitude measurements,...
The development of a numerical criterion to evaluate the stress on models of vasculature has applications in evaluation of human skills, robots and medical tools. This criterion will enable better medical training for endovascular surgery and the development of better medical techniques and tools. We propose to use the stress produced by human blood pressure simulation in the wall of the model of...
In order to reduce fluoroscope usage in endovascular surgery there is a need to develop autonomous catheter insertion systems. We propose a system for tracking the position of the catheter using a magnetic motion capture sensor to provide feedback to a catheter driving mechanism to perform autonomous catheter insertion in major vasculature. Catheter insertion path reconstruction experiments were performed...
Autonomous catheter insertion systems are desirables in fields of cardiology and neurology to reduce the use of X-rays during catheter insertion surgeries. A key point to reach an autonomous catheter insertion system is to provide to a catheter insertion mechanism enough information about the catheter tip position and speed to change its motion according to a predefined point in space to choose a...
