Patent number: 11311204Abstract: In some embodiments, a body cavity shape of a subject is reconstructed based on intrabody measurements of voltages by an intrabody probe (for example, a catheter probe) moving within a plurality of differently-oriented electromagnetic fields crossing the body cavity. In some embodiments, the method uses distances between electrodes as a spatially calibrated ruler. Positions of measurements made with the intrabody probe in different positions are optionally related by using spatial coherence of the measured electromagnetic fields as a constraint. Optionally, reconstruction is performed without using a detailed reference (image or simulation) describing the body cavity shape. Optionally, reconstruction uses further information to refine and/or constrain the reconstruction; for example: images, simulations, additional electromagnetic fields, and/or measurements characteristic of body cavity landmarks. Optionally, reconstruction accounts for time-dependent cavity shape changes, for example, phasic changes (e.g.Type: GrantFiled: January 12, 2018Date of Patent: April 26, 2022Assignee: Navix International LimitedInventors: Eli Dichterman, Yitzhack Schwartz, Yizhaq Shmayahu, Shlomo Ben-Haim

Patent number: 11284813Abstract: In some embodiments, data sensed and/or operational parameters used during a catheterization procedure are used in the motion frame-rate updating and visual rendering of a simulated organ geometry. In some embodiments, measurements of and/or effects on tissue by sensed and/or commanded probe-tissue interactions are converted into adjustments to the simulated organ geometry, allowing dynamic visual simulation of intra-body states and/or events based on optionally partial and/or non-visual input data. Adjustments to geometry are optionally to 3-D positions of simulated data and/or to simulated surface properties affecting geometrical appearances (e.g., normal mapping).

Publication number: 20210386491Abstract: A system for endoscopic surgery, comprising a first robotic arm defining the pose of an endoscopic camera, a second robotic arm defining the pose of a surgical end effector, and an irrigation nozzle configured to inject fluid under a predetermined pressure into a preselected tissue region, to generate a cavity at a surgical site. The cavity enables the camera to take images of the features of the surgical site. A controller is used to control both robotic arms, such that the pose of the endoscopic camera and the pose of the surgical end effector are known to the controller. The camera can then acquire intraoperative images of the cavity, such that an endoscopic operation can be performed in the cavity with the surgical end effector guided using the intraoperative images. Anatomic features imaged intraoperatively by the camera can be identified from preoperative images, using image registration.Type: ApplicationFiled: June 7, 2021Publication date: December 16, 2021Inventors: Yizhaq Shmayahu, Eli Zehavi
