Patent ID: 8083524

Claim:
A simulation system for training and assessing the performance of an endovascular procedure, the system comprising: a control unit and an interface unit, said control unit being configured to communicate with said interface unit to simulate simultaneous handling of at least two different instruments interfaced by said interface unit, wherein interface unit is configured to receive the at least two different instruments along two different axes arranged in a parallel manner, wherein the control unit includes a database of vessels interconnected in a hierarchical structure, each vessel having a diameter and a stiffness, said instruments being tools expandable in simulated vessels, whereby when said tools are expanded, a simulated geometry of said vessels changes resulting in a simulated fluid flow change in the simulated vessels, said simulated fluid flow change affecting fluid flow changes in adjacent simulated vessels, the system being configured to recursively calculate said simulated fluid flow in the simulated vessels and the fluid flow changes in said adjacent simulated vessels, the recursive calculation being a function of at least one parameter, wherein at least one parameter is a result of a real time simulation of a heart function, and the system being further configured to provide the simulated fluid flow change in real time, and insertion of said instruments in the simulated vessels affects the recursive calculation of said simulated fluid flow through the simulated vessels.
