Abstract: A mechanism for providing a trigger signal that is usable to control the collection of electrode calibration data from a catheter. The trigger signal is responsive to a predictive indicator that indicates a likelihood that the catheter is in contact with the anatomical structure, and in particular examples, that the catheter is completely immersed in blood. The predictive indicator is generated using a ratio between two measurements that change responsive to touching the anatomical structure.

Abstract: A mechanism for predicting whether or not contact occurs between an ablation therapy catheter and an anatomical structure. The mechanism proposes two modes of operation. A first mode is used if the ablation therapy catheter is currently performing ablation, e.g. current is being supplied by an ablation controller to electrodes of the ablation therapy catheter, whereas a second mode is used if the ablation therapy catheter is not currently performing ablation. The two modes use two different algorithmic processes to predict whether or not contact occurs between the ablation therapy catheter and the anatomical structure.

Abstract: Embodiments of the present disclosure include a system for determining an error associated with an electrode disposed on a medical device. The system comprises a processor and a memory storing instructions on a non-transitory computer-readable medium. The instructions are executable by the processor to receive an electrode signal from the electrode disposed on the medical device. The instructions are further executable by the processor to receive a plurality of other electrode signals from a plurality of other electrodes disposed on the medical device. The instructions are further executable by the processor to determine that the electrode signal received from the electrode disposed on the medical device is an outlier in relation to the plurality of other electrode signals from the plurality of other electrodes disposed on the medical device, based on a comparison between the electrode signal and the plurality of other electrode signals.

Abstract: Embodiments of the present disclosure include a method for performing patient respiration compensation. The method can include receiving a position sensor signal from a position sensor disposed on a catheter. The method can include determining a position sensor location of the position sensor from the position sensor signal. The method can include receiving a patient reference sensor signal from a patient reference sensor. The method can include determining a patient reference sensor location of the patient reference sensor from the patient reference sensor signal. The method can include determining a weight for the patient reference sensor location. The method can include determining an average of the patient reference sensor location. The method can include determining a compensation for the patient respiration, based on the weighted patient reference sensor location and the average of the patient reference sensor location.
