摘要
A method and apparatus that utilizes a force-time integral for real time estimation of steam pop in catheter-based ablation systems. The apparatus measures the force exerted by a contact ablation probe on a target tissue and an energization parameter delivered to the ablation probe. The exerted force and energization parameter can be utilized to provide an estimation of the probability of steam pop. In one embodiment, the force and energization metrics can be used as feedback to establish a desired contact force and energization level combination to prevent steam popping.
