  • Patent number: 11656735
    Abstract: A virtual endoscopic view shows a surgical area and surrounding anatomy and may also show a position of a surgical instrument in use during a surgical procedure, allowing a surgeon to virtually view the surgical area when direct viewing or actual endoscopic views are incomplete, obstructed, or otherwise unavailable or undesirable. In order to render the endoscopic view, an IGS navigation system may be configured with an observer point and an observer orientation within 3-D space based upon user inputs. A user interface for defining these points allows a user to view a virtual endoscopic preview in real-time while providing inputs, thus improving the likelihood that the resulting virtual endoscopic view is as desired by the user; and reducing time spent redefining and reconfiguring the virtual endoscopic view. The virtual endoscopic preview may provide combinations of static and dynamic images to illustrate the spatial relationship of the provided inputs.

    Abstract: An end effector having loop members with electrodes thereon and are usable with catheter-based systems to measure or provide electrical signals. The end effector can include three loop members that are non-coplanar when expanded unconstrained that become contiguous to a planar surface when the loop members are deflected against the surface, a mechanical linkage that joins the loop members at a distal vertex of the end effector. The end effector may have a lateral gap length between laterally adjacent electrodes approximately twice that of a longitudinal gap length between longitudinally adjacent electrodes. In some configurations, longitudinal electrode bipole pairs having a gap distance approximately equal to the lateral gap distance may be provided by bypassing every other electrode in the longitudinal direction.

  • Patent number: 11648055
    Abstract: Apparatus, consisting of a probe configured to be inserted into contact with a myocardium, and an electrode attached to the probe. A temperature sensor, incorporated in the probe, is configured to output a temperature signal. A pump irrigates the myocardium, via the probe, with an irrigation fluid at a controllable rate, and a radiofrequency (RF) signal generator applies RF power via the electrode to the myocardium, so as to ablate the myocardium. The apparatus also has processing circuitry that measures a temperature of the probe, based on the temperature signal, while the RF power is applied and, when the measured temperature exceeds a preset target temperature, iteratively reduces the RF power applied by the signal generator and concurrently iteratively varies a rate of irrigation of the irrigation fluid provided by the pump, until the measured temperature is reduced to the preset target temperature.

    Abstract: A method includes receiving position signals that are indicative of positions of multiple electrodes disposed on an expandable balloon that is fitted at a distal end of a shaft for engaging a lumen of an organ to occlude the lumen. Based on the received position signals, a change is calculated in one or more dimensions of the balloon between (i) a first configuration in which the balloon is inflated but not engaged in the lumen, and (ii) a second configuration in which the balloon is inflated and engaged in the lumen. Using the calculated change, a degree is estimated to which the balloon occludes the lumen. The estimated degree of occlusion is presented to a user.
