BackgroundThis paper proposes a haptic guidance system to improve catheter navigation within a simulated environment.MethodsThree force profiles were constructed to evaluate the system: collision prevention; centreline navigation; and a novel force profile of reinforcement learning (RL). All force profiles were evaluated from the left common iliac to the right atrium.ResultsOur findings show that providing haptic feedback improved surgical safety compared to visual‐only feedback. If staying inside the vasculature is the priority, RL provides the safest option. It is also shown that the performance of each force profile varies in different anatomical regions.ConclusionThe implications of these findings are significant, as they hold the potential to improve how and when haptic feedback is applied for cardiovascular intervention.
