Abstract
Disclosed herein is a system for assessing ablation lesions. The system includes an ablation catheter configured to ablate a target cardiac tissue site to form an ablation lesion thereon, and a mechanical probe operable to impart mechanical force to the target cardiac tissue site. The mechanical probe includes at least one sensor configured to measure a mechanical response of the target cardiac tissue site to the mechanical force. The system further includes a controller communicatively coupled to the mechanical probe, and configured to determine systolic and diastolic stiffness values of the target cardiac tissue site based on the mechanical response. The controller is further configured to determine a transmurality value of the ablation lesion based on the determined systolic and diastolic stiffness values.
