Abstract: A method and apparatus for electrophysiological assessment, including acquiring electrical signals from tissue at locations in a heart chamber and a computer processor automatically deriving from the electrical signals annotations indicative of times within a heart cycle at which a conduction wave traversed the locations. The method includes receiving an input from a processor user indicating, for a first location in the tissue where the electrical signals include a double-potential signal, a first annotation as a valid annotation. The processor automatically identifies second locations, within a predefined distance from the first location, where the electrical signals include double-potential signals, each having two respective annotations. The method further includes the processor automatically selecting, in response to the selection of the first annotation, one of the two respective annotations as the valid annotation at each of the second locations and displaying the valid annotations on an electroanatomical map of the heart.

Abstract: A registration device, including a wand, a light guide passing through the wand, and a position sensor fixed to the wand. A light source outputs a modulated beam of light into a light guide proximal end, so that the light is emitted from a light guide distal end toward a surface in proximity to a wand distal tip. A detector receives, from the light guide proximal end, light reflected from the surface into the light guide distal end, and outputs a signal indicative of the reflected light intensity. A processor computes a distance from the distal tip of the wand to the surface by extracting a phase difference between the output beam and the reflected light from the signal, and computes a position of the surface in a sensor frame of reference responsively to the computed distance and the location of the distal tip found from the position sensor.

Abstract: 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.

Abstract: A method, including receiving, from electrodes positioned within a heart, first signals from at least three of the electrodes indicating electrical activity in tissue with which the at least three of the electrodes engage, and second signals indicating locations of the at least three electrodes. The second signals are processed to compute the locations of the at least three electrodes and to determine a geometric center of the locations. Based on the signals, an electroanatomical map is generated for an area of the tissue including the geometric center, and an arrhythmia focus is determined in the map. A circle is presented, and within the circle, a region of the map is presented including the geometric center and the focus so that the geometric center on the map aligns with a center of the circle, the region within the circle indicating a spatial relationship between the geometric center and the focus.
