Abstract: A system including a display and a processor. The processor is configured to: (i) receive multiple position measurements indicative of respective positions of an ablation electrode at respective times during an ablation procedure at an ablation site in an organ of a patient, (ii) estimate, based at least on the multiple position measurements, a quality index indicative of a stability of the ablation procedure at the ablation site, and (iii) visualize the quality index to a user on the display.

Abstract: The present disclosure provides systems, apparatuses and methods that provide probe-cavity location and motion data based on probe location and respiration data.

Abstract: A method, consisting of ablating tissue for a time period, measuring a contact force applied during the time period, and measuring a power used during the time period. The method further includes ceasing ablating the tissue when a desired size of a lesion produced in the tissue, as estimated using an integral over the time period of a product of the contact force raised to a first non-unity exponent and the power raised to a second non-unity exponent, is reached.

Abstract: A method, including inserting a probe into a cavity in a subject's body and receiving, from a force sensor in the probe, first readings indicative of a first change in measured contact forces between the probe and the cavity by less than a predetermined limit over at least a predetermined interval of time. The method continues by receiving second readings from the force sensor when the second readings have changed by more than a predetermined force threshold or location coordinates of the probe have changed by at least a predetermined location change threshold. The method continues by receiving third readings indicative of a second change in the measured contact forces between the probe and the cavity by less than the predetermined limit over at least the predetermined interval of time. The method concludes by calibrating a zero-force point for the force sensor according to the third readings.
