Abstract
A method includes, receiving multiple signals from multiple respective electrodes arranged along an inner circumference of a blood vessel that has been ablated. Based on the multiple signals, one or more quality measures of the ablated blood vessel are produced. A graphical presentation indicative of the one or more quality measures, is displayed to a user in a two-dimensional (2D) polar coordinate system.
Claims18
A method, comprising:
- receiving multiple signals from multiple respective electrodes of a distal end assembly of a catheter, the multiple respective electrodes being arranged along an inner circumference of a blood vessel that has been ablated;
- producing, based on the multiple signals, one or more quality measures of the ablated blood vessel;
- displaying, to a user, a graphical presentation indicative of the one or more quality measures, in a two-dimensional (2D) polar coordinate system, the graphical presentation comprising:
- a first circle or ellipse comprising a first radius, the first circle or ellipse being indicative of the inner circumference at a first position along a longitudinal axis of the blood vessel;
- and
- a second circle or ellipse comprising a second radius, different from the first radius, the second circle or ellipse being indicative of the inner circumference at a second position along the longitudinal axis of the blood vessel;
- and
- ablating, by the distal end assembly, the blood vessel on a basis of the graphical presentation indicative of the one or more quality measures.

A system, comprising:
- a distal end assembly of a catheter, the distal end assembly comprising ablation electrodes;
- a processor, which is configured to:
- (i) receive multiple signals from multiple respective electrodes of the distal end assembly of the catheter, the multiple respective electrodes being arranged along an inner circumference of a blood vessel that has been ablated, (ii) produce, based on the multiple signals, one or more quality measures of the ablated blood vessel, and (iii) produce a graphical presentation indicative of the one or more quality measures, in a two-dimensional (2D) polar coordinate system, the graphical presentation comprising:
- (i) a first circle or ellipse comprising a first radius, the first circle or ellipse being indicative of the inner circumference at a first position along a longitudinal axis of the blood vessel;
- and (ii) a second circle or ellipse comprising a second radius, different from the first radius, the second circle or ellipse being indicative of the inner circumference at a second position along the longitudinal axis of the blood vessel;
- and
- a display, which is configured to display the graphical presentation to a user, the ablation electrodes being configured to further ablate the blood vessel on a basis of the graphical presentation indicative of the one or more quality measures.
