Ablation systems and methods detect and address distortion caused by a variety of factors. A method includes measuring a temperature curve at target tissue; applying ablation energy to the target tissue; determining a peak temperature on the temperature curve; if the peak temperature is greater than the predetermined peak temperature, determining a time at which the temperature curve crosses to a lower temperature; and if the determined time is greater than a predetermined time, generating a message indicating that the target tissue was successfully ablated. Another method includes determining a distance between a remote temperature probe and an ablation probe, applying ablation energy to target tissue, measuring temperature at the remote temperature probe, estimating ablation size based on the determined distance and the temperature measured by the remote temperature probe, and determining whether the target tissue is successfully ablated based on the estimated ablation size.

A method for treating cancer tumors and metastatic cancer cells by disrupting the tumor by sequentially or concurrently administering an ablative energy in combination with immunomodulation and/or pharmacological application, in one or more cycles, where the physical disruption is applied at levels sufficient to create the abscopal effect. That effect is generated by stimulating the immune cells in the microenvironment. The tumor is treated in a way permitting the remaining cells or elements in the tumor microenvironment to exert net immune stimulation with also long-term memory cells to fight subsequent appearing tumor in the future. Adding immune modulators injected in situ systemically or embedded in slow releasing means locally or systemically will boost the immune response to the cancer.

A method includes receiving: (i) a position of a target tissue intended to be ablated in an organ of a patient and having a predefined pattern, and (ii) an energy level of an ablation signal intended to be applied to the target tissue. One or more selected ablation electrodes that, when applying the ablation signal, produce together a lesion having a shape that covers the predefined pattern, are selected in a catheter that is inserted into the organ and has an array of ablation electrodes. In response to verifying that: (i) the one or more selected ablation electrodes are positioned on the target tissue, and (ii) a contact force between the one or more selected ablation electrode and the target tissue is larger than a force threshold, the ablation signal is applied to the target tissue using the one or more selected ablation electrodes.

A method and system for artificial intelligence-based radiofrequency ablation parameter optimization and information synthesis are provided. The method is applied to a radiofrequency ablation controller including a processor and an artificial intelligence module. The processor of the radiofrequency ablation controller preprocesses sample data and sends the preprocessed sample data to the artificial intelligence module. The artificial intelligence module establishes an artificial neural network model according to the preprocessed sample data and a radiofrequency ablation control parameter for the sample data. The processor preprocesses signals collected by sensors on a plasma wand. The artificial intelligence module imports preprocessed sensor data into the artificial neural network model for analysis and fusion, to obtain the radiofrequency ablation control parameter.
