REBOA (Resuscitative Endovascular Balloon Occlusion of the Aorta) is a potentially life saving procedure to stem bleeding into the abdomen and lower body. A balloon catheter is inserted through into the common femoral artery in the groin specific zones in the aorta and inflated, temporarily blocking blood flow while repairs are effected. It is typically performed without live imaging assistance, and animal-based training is not suitable. A simulation-based training system is needed to allow military and civilian trauma and emergency physicians to learn standard technique and use of new REBOA catheters.

Expanding our previous works on interventional radiology simulation, we are developing the physics-based models for catheter and guidewire motion, blood flow and graphical rendering towards a novel simulator for REBOA that will include physical vascular access, simulated passage of the IR instruments into the aorta with accompanying training/educational content, device withdrawal and closure.

The system is designed to be compatible with CODA balloon catheters, the newer ER-REBOA catheter and other similar systems. Motion of and reaction forces on the devices passing through the vasculature, and blood flow within virtual vessels is computed in real-time, and synthetic views of virtual instrument motion can be displayed to the trainee to provide understanding of the procedure and illustrate when errors are committed.

Errors such as venous access and incorrect location of balloon inflation can be detected. The underlying software architecture links the wireless, battery powered trackers to a portable tablet or similar interface, which can record performance for later review and evaluation.
