摘要： A method includes receiving a 3D image of a portion of an organ including a cavity, the image comprising voxels having respective values. A wall of the cavity is identified in the image, by (i) positioning virtual solid objects inside respective sub-volumes of the cavity, (ii) moving the virtual solid objects inside the cavity according to a predefined rule of motion, (iii) while the virtual solid objects move inside the cavity, adapting the traversed voxels to predefined value indicative of the interior of the cavity, (iv) responsively to detecting that a virtual solid object comes into contact with the wall, rolling the virtual solid object over the wall, and adapting a surface of the virtual solid object with the values of the voxels over which the surface rolls, and (v) converting adapted voxel values that are lower than a threshold voxel value into the predefined value indicative of the interior.

摘要： A method for generating a skeleton in an image of a cavity of an organ of a body includes receiving a map of the cavity, the map including surface voxels and interior voxels. A subset of the interior voxels is generated, of candidate locations to be on the skeleton. The subset is pruned by removing outlier candidate locations. Using a geometrical model including a statistical model, the candidate locations remaining in the pruned subset are spatially compressed. The compressed candidate locations are connected to produce one or more centerlines of the skeleton. At least the skeleton is displayed to user.

摘要： Tools used within a surgical area may be equipped with sensors that allow them to be tracked within the magnetic field of an image guided surgery (IGS) system. The IGS system may be configured to detect various movement patterns of the tools, which may be mapped to and associated with corresponding actions or inputs to the IGS system. In one example, a registration probe may be moved along the x-axis and y-axis, with detected movements identified and received by the IGS system as movements of a mouse cursor on a display of the IGS system. In another example, the registration probe may be moved in a circular pattern, or quickly moved along any of the x-axis, y-axis, or z-axis, with each being configured to cause the IGS system to zoom a display, change a view, record video, or other actions.

摘要： An apparatus includes a handle, a catheter, extending distally from the handle, an end effector extending distally from the catheter, a deflection assembly, and a load limiting assembly. The deflection assembly is configured to deflect the end effector away from a longitudinal axis of the catheter. The deflection assembly includes an input member and a translating assembly. The input member is configured to drive the translating assembly to deflect the end effector away from the longitudinal axis. The load limiting assembly is configured to decouple the input member from the translating assembly at a predetermined load such that the input member is inhibited from driving the translating assembly when the input member is decoupled by the load limiting assembly.

摘要： A system includes an expandable distal-end assembly, a proximal position sensor, a distal position sensor, and a processor. The expandable distal-end assembly is coupled to a distal end of a shaft for insertion into a cavity of an organ of a patient. The proximal and distal position sensors are located at a proximal end and a distal end of the distal-end assembly, respectively. The processor is configured to estimate a position and a longitudinal direction of the proximal sensor, and a position of the distal sensor, all in a coordinate system used by the processor. The processor is further configured to project the estimated position of the distal sensor on an axis defined by the estimated longitudinal direction, and calculate an elongation of the distal-end assembly by calculating a distance between the estimated position of the proximal sensor and the projected position of the distal sensor.

摘要： A system includes a probe, a processor, and a bubble detector. The probe is configured for insertion into a lumen of a patient and is coupled to an irrigation pump. The processor is configured to control delivery of irrigation fluid to the probe by turning on and controlling the irrigation pump. The bubble detector is coupled to a proximal portion of the probe. In response to the irrigation pump being turned on, the bubble detector is configured to automatically start detection of gas bubbles in the irrigated fluid, and transmit fail-safe signals indicating fail-safe bubble detection is operational. The processor is further configured to monitor the fail-safe signals and, in absence of fail-safe signals, to automatically disable delivery of the irrigation fluid.

摘要： A method includes receiving multiple electrophysiological (EP) signals acquired by multiple electrodes of a multi-electrode catheter that are in contact with tissue in a region of a cardiac chamber, and respective tissue locations at which the electrodes acquired the EP signals. The region is divided into two sections. Using the EP signals acquired by the electrodes, local activation times (LAT) are calculated for the respective tissue locations, and found are: a first section of the two sections having a smaller average LAT value, and a second section of the two sections having a higher average value. Determined are a first representative location in the first section, and a second representative location in the second section. A propagation vector is calculated between the first and second representative locations, that is indicative of propagation of an EP wave that has generated the EP signals. The propagation vector is presented to a user.
