Device specific finite element models for simulating endovascular treatment

A method for simulating medical device dynamics, the method comprising:

• storing a computer readable database comprising medical device models of different sized flow diverters, each model comprising a plurality of braided strands, each strand being represented by a plurality of serially linked beam elements with a virtual diameter that is equal to a diameter of the strand;
• receiving clinical data of a patient;
• selecting a plurality of the medical device models from the database;
• virtually constructing, by the one or more processors, each of the medical device models by modeling the plurality of braided strands to have a pitch and a number of clockwise and anti-clockwise strands;
• virtually constraining, by one or more processors, each of the medical device models by imposing one or more radial displacement boundary conditions applied in time using a smooth step function;
• virtually constructing, by the one or more processors, an anatomical structure model based on the patient clinical data;
• simulating a deployment of the plurality of the medical device models in the anatomical structure model;
• simulating hemodynamic outcomes after simulating the deployment of the plurality of the medical device models in the anatomical structure model;
• generating a report comprising one or more of hemodynamic outcome data and medical device model performance data;
• and
• selecting a medical device for use in an endovascular medical device placement procedure based at least in part on one or more of the hemodynamic outcome data and the medical device model performance data.
