Patent number: 11878095Abstract: A medical probe includes a shaft, an expandable membrane and a probe maneuvering assembly (PMA). The shaft is configured for insertion into a cavity of an organ of a patient. The PMA is located inside the expandable membrane and includes a first elastic element, which is fitted along a longitudinal axis of the PMA and is configured to expand the membrane by shortening the PMA, and to collapse the membrane by elongating the PMA. The PMA further includes a second elastic element, which surrounds at least a portion of the first elastic element and is configured to deflect the membrane relative to the longitudinal axis.Type: GrantFiled: June 17, 2021Date of Patent: January 23, 2024Assignee: Biosense Webster (Israel) Ltd.Inventors: Christopher Thomas Beeckler, Joseph Thomas Keyes, Kevin Justin Herrera, Alexander David Squires, Kevin Mark Okarski

Publication number: 20230075838Abstract: Embodiments of the present invention include a medical probe having an insertion tube, a basket assembly, an axial electrode, and a plurality of radial electrodes. The insertion tube is configured for insertion into a body cavity of a patient. The basket assembly has a proximal end that is connected distally to the insertion tube and includes a plurality of resilient spines, which are configured to bow radially outward from an axis of the basket assembly and are conjoined at a distal end of the basket assembly. The axial electrode is disposed at the distal end of the basket assembly, having a diameter of at least 1.5 millimeters, and is configured to contact tissue in the body cavity. The plurality of radial electrodes are configured to contact the tissue in the body cavity and include radial electrodes disposed on the spines.Type: ApplicationFiled: September 9, 2021Publication date: March 9, 2023Inventors: Assaf Govari, Christopher Thomas Beeckler, Joseph Thomas Keyes, Kevin Justin Herrera, Alexander David Squires
