摘要：
A method and device for determining the transmurality and/or continuity of an isolation line formed by a plurality of point contact ablations. In one embodiment, a method for determining the size of a lesion (width, depth and/or volume) is disclosed, based on contact force of the ablation head with the target tissue, and an energization parameter that quantifies the energy delivered to the target tissue during the duration time of the lesion formation. In another embodiment, the sequential nature (sequence in time and space) of the ablation line formation is tracked and quantified in a quantity herein referred to as the “jump index,” and used in conjunction with the lesion size information to determine the probability of a gap later forming in the isolation line.
