To facilitate subsequent location of a point along a patient's tubular body structure (e.g., a circulatory system vessel), a marker structure is inserted into and along the lumen of that tubular body structure. At the desired point along the lumen, a distal portion of the marker structure is made to pass out through a side wall of the tubular body structure so that it projects from that side wall and visibly and/or radiologically marks the desired point along the tubular body structure. The marker structure may also be used as an anchor for other instrumentation brought up to the outside of the tubular body structure (e.g., for use in further treatment of the tubular body structure).

[ The invention claimed is:] [1.]1. A marker structure for use in marking a predetermined location along a patient's tubular body structure comprising:an elongated longitudinal structure configured for axial insertion into and along a lumen of the tubular body structure to reach the predetermined location, the elongated longitudinal structure having a distal portion configured to pierce a side wall of the tubular body structure at the predetermined location and to project from the side wall through any adjacent tissue outside of the tubular body structure.
