  • Patent number: 12121289
    Abstract: Tissue treatment systems for cardiac surgical procedures can include an ablation and monitoring assembly having a first ablation element, a second ablation element, and a monitoring mechanism. Treatment methods may involve placing an ablation and monitoring assembly of the tissue treatment system at a patient tissue treatment site, applying a first ablative energy to a first tissue location via the first ablation element and a second ablative energy to a second tissue location via the second ablation element, monitoring a condition of the first tissue location with the monitoring mechanism, and modulating application of the first ablative energy to the first tissue location in response to the condition of the first tissue location while maintaining application of the second ablative energy to the second tissue location. Embodiments also include techniques for assessing a conduction delay across a lesion that involve evaluating local activation rates on various sides of a lesion.

  • Publication number: 20240168189
    Abstract: In certain embodiments, a method includes generating a set of average velocity controls based on received seismic data, generating a depth to basement model based on received potential fields data, and generating an average velocity model using an interpolation model to interpolate the set of average velocity controls and the depth to basement model. The method may also include generating a variogram model based on the set of average velocity controls, and generating the average velocity model using the interpolation model to interpolate the average velocity controls, the variogram model, and the depth to basement model. The interpolation model may be Kriging with external drift. The external drift may be based on the depth to basement model. Additionally, the method includes generating a structural map of a subsurface formation using the average velocity model.

  • Publication number: 20230380899
    Abstract: Systems and methods for forming a lesion on an endocardial tissue of a patient's heart involve placing an ablation assembly inside of the heart and adjacent to the endocardial tissue, and placing a guiding assembly outside of the heart. An ablation assembly includes an ablation element and a first attraction element, and a guiding assembly includes a second attraction element. First and second attraction elements can be attracted via magnetism. Techniques involve forming an ablation on the cardiac tissue of a patient's heart with an ablation element of the ablation assembly. Optionally, techniques may include moving the second attraction element of the guiding assembly relative to the patient's heart, so as to effect a corresponding movement of the ablation element of the ablation assembly.
