A Systematical Analysis of <i>In Vivo</i> Contact Forces on Virtual Catheter Tip/Tissue Surface Contact during Cardiac Mapping and Intervention

Abstract

This study shows that mapping and ablation using a robotic sheath guidance system are critically dependent on generated force. These findings suggest that ablative lesion size is optimized by the application of 10-20 grams of contact force, although mapping requires lower-force application to avoid image distortions.
