CATHETER ASSEMBLY TRACKING

Abstract: a system for use with an electrophysiological procedure includes a catheter assembly including a plurality of coaxially disposed catheter elements, the plurality of catheter elements movable with respect to each other along the longitudinal axis. the system further includes a controller configured to generate a first position of the first catheter element based on the first electrical signal and generate a second position of the second catheter element based on the second electrical signal and, in response to a detected longitudinal movement of the second catheter element along the longitudinal axis with respect to the first catheter element, apply a historical correction to the first and second positions based on a previously determined first and second position vector to obtain an initially corrected first and second positions. the control further generates an anatomical map of the electrophysiological procedure with a visualization of the catheter assembly including the longitudinal adjustment.
