Patent number: 11234763Abstract: A method of ablating tissue comprising adjusting a set of dosing parameters for an ablation catheter based on a set of optical image-derived parameters generated from optical image-derived information obtained from direct optical imaging of the tissue while the ablation catheter is in contact with the tissue. The set of optical image-derived parameters may include a color profile, a blanching parameter, or a contact angle of a distal tip of the ablation catheter. The method may further comprise comparing the color profile to a signature profile and adjusting the set of dosing parameters based on the comparison between the color profile and the signature profile.Type: GrantFiled: September 6, 2018Date of Patent: February 1, 2022Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: John B.

Publication number: 20220000546Abstract: Systems, devices, and methods for electroporation ablation therapy are disclosed herein, including an inflatable member for positioning an ablation device within a pulmonary vein ostium. An apparatus can include first and second shafts moveable relative to one another, first and second electrodes configured to generate an electric field for ablating tissue, and an inflatable member disposed between the first and second electrodes. In some embodiments, the inflatable member is configured to transition from an undeployed configuration to a deployed configuration in response to movement of the first and second shafts. In some embodiments, the inflatable member in the deployed configuration can engage a wall of a pulmonary vein ostium and direct the electric field generated by the first and second electrodes toward the wall.Type: ApplicationFiled: March 19, 2021Publication date: January 6, 2022Applicant: Farapulse, Inc.Inventors: Raju VISWANATHAN, Gary L.
