Patent number: 11622713Abstract: Methods for estimating of the effectiveness of catheter ablation procedures to form lesions. Lesion effectiveness parameters are received, and effectiveness of a corresponding ablation (optionally planned, current, and/or already performed) is estimated. The estimating is based on use by computer circuitry of an estimator constructed based on observed associations between previously analyzed lesion effectiveness parameters, and observed lesion effectiveness. The estimator is used by application to the received lesion effectiveness parameters.Type: GrantFiled: November 16, 2017Date of Patent: April 11, 2023Assignee: Navix International LimitedInventors: Shlomo Ben-Haim, Yizhaq Shmayahu, Yitzhack Schwartz, Haim Rodriguez, Eli Dichterman, Zalman Ibragimov, Yaara Yarden

Patent number: 11583202Abstract: Systems and method for remote field measurement-based mapping of anatomical structures (e.g., using impedance image of electrical fields) are described. In some embodiments, an image of features within a target region is produced by analysis of a spatial pattern of field measurements made in a measurement region remote from the target region features; for example, but not exclusively, by treating the spatial arrangement of field measurements in some portion of the measurement region as indicating the spatial (e.g., angular and/or distance) arrangement of features (e.g., anatomical structure of topography and/or tissue type) in the target region.Type: GrantFiled: August 16, 2018Date of Patent: February 21, 2023Assignee: Navix International LimitedInventor: Shlomo Ben-Haim

Publication number: 20230042140Abstract: Degree of occlusion is monitored for an occlusive device configured to occlude passage of fluid between two compartments in a lumenal space of a body of a patient. In some embodiments, changes in an electrical signal measured from the body of the patient are induced by perturbing the fluid; for example, by “tagging” a portion of fluid with a perturbation of temperature and/or composition. The degree of occlusion is estimated based on the measured changes. The electrical signal changes may be indicative of fluid movements redistributing the perturbed fluid among the two compartments; for example, by diffusion, mixing, and/or jetting of fluid.Type: ApplicationFiled: December 30, 2020Publication date: February 9, 2023Applicant: Navix International LimitedInventor: Shlomo BEN-HAIM
