Researchers have developed a new method for controlling steerable catheters, focusing on the dynamics of interaction between the catheter and tissue. The approach uses a partial-physics feedforward to cancel reliable bending dynamics, exposing a linear interaction-dynamics model. A predictive optimizer then regulates this state while adhering to hard constraints on contact force, tendon force, and curvature. This method was tested in a simulation, showing a significant reduction in approach error and successful reconciliation of tracking with force safety bounds, even under simulated cardiac motion. AI
