Key Points

Mechanical deformation correlated strongly with contact force across applied loads of 10 to 80 g, establishing a clear link between force and insertion depth.
Assessment using perpendicular catheter insertion into ex vivo porcine myocardium was coupled with a 3-parameter Mooney-Rivlin model simulating hyper-elastic tissue.
Computational modeling accurately reflects cardiac catheter ablation mechanics in porcine tissue; further preclinical validation is required before clinical use.
