Abstract
The present disclosure provides systems, apparatuses and methods that identify end expirium data based on catheter movement data.
Claims19
A method of identifying an end expirium, the method comprising:
- (i) identifying an initial end expirium prior to ablation, the initial end expirium associated with a first catheter position;
- (ii) determining catheter velocity and catheter position during ablation;
- and
- (iii) identifying an estimated end expirium during ablation among a plurality of end expiriums when the catheter velocity is less than a predetermined velocity, and when the catheter position is less than a predetermined distance from the first catheter position;
- wherein the estimated end expirium is identified among the plurality of end expiriums based on the estimated end expirium having a lowest catheter velocity for a longest period of time among the plurality of end expiriums.
2 more elements
A method, comprising:
- (i) identifying an initial end expirium prior to ablation;
- (ii) monitoring a catheter velocity from a first time corresponding to the initial end expirium to a second time corresponding to ablation;
- (iii) identifying a period between the first time and the second time during which the catheter velocity is greater than a velocity threshold;
- and
- (iv) setting an ablation tag at a position of the catheter during ablation, responsive to the identified period being greater than a duration threshold.

2 more elements
A system for identifying an end expirium, the system comprising:
- a catheter configured to be inserted into a cavity of a patient;
- at least one sensor configured to detect a position of the catheter;
- and
- a processor configured to identify an estimated end expirium during ablation among a plurality of end expiriums based on the estimated end expirium having a lowest catheter velocity for a longest period of time among the plurality of end expiriums.
