Researchers have developed a new method called Progressive Experience Fusion (PEF) to train controllers for autonomous endovascular navigation. This technique aims to improve the success rate of delivering mechanical thrombectomy, particularly in complex vascular anatomies. In simulations, PEF achieved a 74% success rate, significantly outperforming other methods like Soft Actor-Critic and a base TD-MPC2 controller. Further testing showed a PEF controller with adaptive planning achieved 90% success in unseen vasculatures and demonstrated successful transfer to an in vitro patient vasculature, improving path ratio from 63% to 80% with fine-tuning.
