Publication number: 20240032997Abstract: Devices, systems, and methods of the present disclosure can overcome physical constraints associated with catheter introduction to facilitate the use of a catheter with a large distal portion as part of a medical procedure benefitting from such a large distal portion, such as, for example, cardiac ablation. More specifically, devices, systems, and methods of the present disclosure can compress an expandable tip of a catheter from an expanded state to a compressed state along a tapered surface of an insertion sleeve for advancement of the expandable tip into vasculature of a patient. The tapered surface of the insertion sleeve can, for example, apply compressive forces at an angle against the advancing expandable tip. As compared to other approaches to the application of compressive force to an expandable tip, compressing the expandable tip using an angled force can reduce the likelihood of unintended deformation of the expandable tip.Type: ApplicationFiled: September 28, 2023Publication date: February 1, 2024Inventors: Doron Harlev, Andrew Miles Wallace, Luke Tsai, Ian Matthew Collier

Publication number: 20230414279Abstract: An ablation catheter having an expandable tip is disclosed herein. In some implementations, the ablation catheter includes a catheter shaft, an irrigation lumen, and an expandable tip secured to the catheter shaft. In some implementations, the expandable tip includes a balloon defining a volume in communication with the irrigation lumen. In these and other implementations, the balloon defines a plurality of irrigation orifices in fluid communication with the volume. In these and other implementations, the expandable tip comprises an ablation electrode and a plurality of sensing electrodes disposed along a distal section of the balloon. In these and still other implementations, the sensing electrodes disposed along the distal section of the balloon can be electrically isolated from and bounded by the ablation electrode.Type: ApplicationFiled: September 6, 2023Publication date: December 28, 2023Inventors: Doron Harlev, Ian Matthew Collier, Andrew Miles Wallace

Patent number: 11826095Abstract: Ablation systems of the present disclosure facilitate the safe formation of wide and deep lesions. For example, ablation systems of the present disclosure can allow for the flow of irrigation fluid and blood through an expandable ablation electrode, resulting in efficient and effective cooling of the ablation electrode as the ablation electrode delivers energy at a treatment site of the patient. Additionally, or alternatively, ablation systems of the present disclosure can include a deformable ablation electrode and a plurality of sensors that, in cooperation, sense the deformation of the ablation electrode, to provide a robust indication of the extent and direction of contact between the ablation electrode and tissue at a treatment site.Type: GrantFiled: November 15, 2021Date of Patent: November 28, 2023Assignee: AFFERA, INC.Inventors: Doron Harlev, Ian Collier, Andrew Miles Wallace, Jonathan Matthew Bond

Publication number: 20230012307Abstract: Pulmonary vein isolation catheters and associated devices, systems, and methods are disclosed herein. In some embodiments, a pulmonary vein isolation catheter includes a tip section having an expandable portion and a deployment member. The expandable portion includes a plurality of mesh electrode panels that are electrically insulated from one another. The expandable portion is mechanically coupled to (i) the deployment member at a distalmost portion of the tip section and (ii) a distal end portion of a catheter shaft. The expandable portion is expandable and compressible via proximal and distal movement, respectively, of the deployment member. In some embodiments, the expandable portion in a deployed state is pear- or onion-shaped and includes a nose portion and/or an active body portion. The nose portion can be insulated and/or configured to fit within a pulmonary vein and position the active body portion against tissue about the ostium of the pulmonary vein.Type: ApplicationFiled: December 16, 2020Publication date: January 12, 2023Inventors: Doron Harlev, Andrew Miles Wallace, Paul Brian Hultz
