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: A method for detecting or monitoring respiratory or cardiac health of a patient includes measuring any intravascular or intracardiac pressure (IVP) of a patient over a period of time, said IVP including a measured respiratory wave, defining respiratory effort of the patient as a peak-to-peak amplitude of said respiratory wave, and using the respiratory effort to detect or monitor respiratory and cardiac health of the patient by comparing the respiratory effort with a known value of respiratory effort or by monitoring changes in the respiratory effort of the patient over another period of time.
