Tubular body structure marking methods and apparatus

Abstract

Abstract 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).
