A catheter control device is developed, which is capable to simulate force and tactile feeling of interaction between the cardiovascular structure and catheter tip. The objective is to improve radiofrequency ablation (RFA) safety and reliability for MR-guided cardiac electrophysiological (EP) therapy. This MR-conditional haptic interface can be integrated with the clinically-used catheters and kits for MR-guided EP. Detailed validation was conducted in simulated RFA tasks performed by 12 subjects to evaluate the effect of such haptic feedback on improved catheter manipulation and lesion RFA. The task improvement in terms of in safety, accuracy and RFA sufficiency demonstrates the clinical potential.
