Patent number: 11666352Abstract: Apparatus, including a probe having a distal end insertable into a nasal sinus of a human patient, and a location sensor positioned within the distal end. A sinuplasty balloon is positioned on the distal end at a selected opening of the nasal sinus. A processor receives first signals from the location sensor while the distal end is inserted into the nasal sinus and prior to positioning of the balloon at the selected opening, and generates a first map of the sinus. The processor inflates the balloon when it is at the selected opening, so as to enlarge the selected opening, and subsequently deflates the balloon. The processor then receives second signals from the location sensor and generates therefrom a second map of the sinus. The processor registers the first map with the second map and generates from the registered maps a numerical increase in size of the selected opening.Type: GrantFiled: October 5, 2020Date of Patent: June 6, 2023Assignee: Biosense Webster (Israel) Ltd.Inventors: Zvi Dekel, Akram Zoabi, Yoav Pinsky, Noam Racheli, Itamar Bustan

Patent number: 11103249Abstract: A method includes inserting into a patient organ a catheter including a position sensor, a device and a handle. The position sensor is attached to a distal end of the catheter. The device is movable along the catheter. The handle includes a control for navigating the device along the catheter to a target location in the patient organ. Based on a location of the position sensor, a target position of the control on the handle that corresponds to the target location of the device is estimated. A marker is set to mark the target position of the control on the handle, and the device is navigated to the target location by setting the control to the marker.Type: GrantFiled: May 1, 2019Date of Patent: August 31, 2021Assignee: Biosense Webster (Israel) Ltd.Inventors: Akram Zoabi, Fady Massarwi

Patent number: 11065064Abstract: An apparatus, including a magnetic field generator, a first magnetic field sensor configured for attachment to a proximal end of a surgical tool configured for insertion into a body, and a calibration device that includes a second magnetic field sensor and a proximity sensor, wherein the field sensors generate respective location signals responsive to a magnetic field emanating from the generator and traversing the field sensors. The apparatus includes a control unit, which receives the signals from all the sensors, extracts respective location and orientation coordinates of the field sensors based on the signals, computes a conversion relation between the coordinates of the first sensor and a distal end of the tool that is brought into contact with the calibration device, and subsequently applies the conversion relation, together with the coordinates of the first sensor, in providing a visual indication of a location of the distal end inside the body.Type: GrantFiled: November 14, 2017Date of Patent: July 20, 2021Assignee: Biosense Webster (Israel) Ltd.Inventors: Yoav Pinsky, Akram Zoabi, Itamar Bustan, Michal Alroy Levy

Publication number: 20200197106Abstract: A method and system for automatic landmark registration and registration using trajectory information and shape sensing during an endoscopic procedure, such as bronchoscopy, are described herein. A segmentation centerline of airways of a lung may be generated based on a pre-operative computed tomography (CT) image of the lung. Landmarks may be automatically detected on the segmentation centerline corresponding to bifurcations in the airways of the lung. A location data point cloud of locations of a catheter through the airways of the lung during navigation may be generated. A bounding volume of the airways of the lung may be generated and a bounding volume centerline may be detected. Landmarks may be detected on the bounding volume centerline for the same bifurcations. Then, the two sets of landmarks may be mapped as part of registration. The trajectory information with shape sensing may be used to provide non-rigid or fine registration.Type: ApplicationFiled: March 2, 2020Publication date: June 25, 2020Applicant: Biosense Webster (Israel) Ltd.Inventors: Zvi Dekel, Akram Zoabi, Yaniv Ben Zrihem, Noam Rachli, Helen Volfson
