摘要： A system for electrophysiological measurement includes a probe having a distal end configured for insertion into a body cavity of a living subject and including an array of electrodes that are disposed along the distal end and are configured to contact tissue at multiple locations within the body cavity. A processor is configured to acquire signals from the electrodes over a period of time during which the probe moves within the body cavity, to compute, in response the signals, metrics that are indicative of a respective quality of contact between each of the electrodes and the tissue over the period of time, and to output an indication of the metrics to a user of the system.

摘要： A medical apparatus includes a probe configured for insertion into a body of a patient. The probe includes electrodes configured to contact tissue within the body. The apparatus further includes a display screen, a position-tracking system configured to acquire position coordinates of the electrodes, and a processor. The processor is configured to acquire electrophysiological signals from a group of the electrodes in a sequence of time intervals, extract electrophysiological parameters from the signals, and for each time interval, compute a measure of consistency of the parameters extracted from the signals. The processor is further configured to render to the display screen a three-dimensional map of the tissue while superimposing on the map a visual indication of the extracted parameters for which the measure of consistency satisfied a consistency criterion, and automatically discarding from the map the parameters for which the measure of consistency did not satisfy the criterion.

摘要： A medical apparatus includes a probe configured for insertion into a body of a patient. The probe includes electrodes configured to contact tissue of a region within the body. The apparatus further includes a display screen a position-tracking system, and a processor. The processor is configured to acquire electrophysiological signals from the electrodes, to extract electrophysiological parameters from the signals, to compute a measure of consistency of the electrophysiological parameters at each of the locations with respect to a weighted median of the parameters extracted at neighboring locations, and to render to the display screen a map of the tissue while overlaying on the map a visual indication of the extracted electrophysiological parameters for which the measure of consistency satisfied a predefined consistency criterion, and automatically omitting from the map the electrophysiological parameters for which the measure of consistency did not satisfy the criterion.

摘要： Apparatus and methods are provided for mapping and displaying three dimensional surgical pathways within imaging of cranial structures derived from voxels of a cranial scan. Entry voxel and target voxel are selected as pathway endpoints. A series of respective neighbor voxels are mapped between the entry voxel and the target voxel to define a pathway. For each voxel Vxi,yi,zi in the series, an immediately succeeding voxel of voxel Vxi,yi,zi is selected from among the group of neighbor voxel of voxel Vxi,yi,zi which excludes neighbor voxels of the immediately preceding voxel of voxel Vxi,yi,zi . The selection is made by comparing selection weights determined based on relative distances with respect to the endpoint voxels and relative distance from voxels within a predetermined distance that represent at least a threshold density. The voxels of the pathway are then selectively highlighted in a displayed view to provide a visualization of the 3D surgical pathway.

摘要： Methods, apparatus, and systems for medical procedures are disclosed herein and include receiving a first set of biometric data of a first modality for a first portion of a body part, determining first visual characteristics based on the first set of biometric data, receiving a second set of biometric data of a second modality for a second portion of the body part, the second portion of the body part being a subset of the first portion of the body part, and determining second visual characteristics based on the second set of biometric data. A first view including the first portion of the body part rendered with the first visual characteristics may be provided and second view comprising the second portion of the body part rendered with the second visual characteristics may be provided, the second view superimposed on the first view at a location on the first view corresponding to the second portion of the body part.

摘要： A guidewire, consisting of a flexible biocompatible tube, having a tube distal end, the tube containing an internal lumen and being configured to be inserted into an orifice of a body of a living subject. A planar resilient strip is inserted into the internal lumen, the strip having a strip proximal end and a strip distal end fixed to the tube distal end. A coil spring is fixed to the strip proximal end so that an axis of symmetry of the coil is coplanar with the strip, the coil spring containing a coil lumen. A wire is threaded through the coil lumen and has a termination fixed to the strip distal end, so that pulling on the wire causes the strip and the tube to bend.
