Abstract:
1. A method of real time monitoring the position of a portion of a second vessel, which branches from a first vessel in a human patient comprising: acquiring a multi-dimensional data set of a portion of first and second vessels where the second vessel branches from the first vessel; delivering at least one marker attached to a catheter in vivo to one of the first and second vessels at a juncture where the second vessel branches from the first vessel; securing the marker to one of the first and second vessels at the juncture where the second vessel branches from the first vessel by expanding a stent-graft to pin at least the catheter to which the at least one marker is attached against a wall of the first vessel; determining the position of the marker in real time; and updating the position of a portion of the multi-dimensional data set relative to the juncture between the first and second vessels in real time based on change in position of the marker caused by motion of the anatomy of the human patient.
