Radiological marker board with movable indicators

摘要

A system is disclosed for locating positions in the vasculature of a human patient for the purpose of rendering treatment or making a diagnosis therein during a catheterization procedure, such as a procedure to implant an intraluminal arterial graft. The system includes a board which rests under the patient during the procedure which has two markers that can be detected under fluoroscopy. The markers can be moved backwards and forwards along a track in the board to pinpoint various locations in the blood vessel of interest, for example, the points of attachment for the ends of an arterial graft. One of the markers also can be pivoted about the track to represent the angle at which a particular blood vessel is disposed in the patient. The markers can be locked into position with brakes for the duration of the procedure.
