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.
Claims20
A method, comprising:
- performing, by a distal end assembly of a catheter, a first ablative procedure of an inner circumference of a blood vessel;
- performing an electro-anatomical mapping procedure comprising:
- receiving multiple signals from multiple respective electrodes of the distal end assembly, the multiple respective electrodes being arranged along the inner circumference of the blood vessel that has been ablated;
- producing, based on the multiple signals, one or more quality measures of the ablated blood vessel;
- and
- displaying, to a user, a graphical presentation indicative of the one or more quality measures, in a two-dimensional (2D) polar coordinate system;
- and
- performing, by the distal end assembly, a second ablative procedure of 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;
- 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.
