ABSTRACT:
An expandable reinforcing member or stent of the invention is used inside a body lumen, especially, in patient's artery for opening and holding a lesion or stenosis with a branch. The expandable reinforcing member is formed of at least two hollow mesh portions situated away from each other along an axial direction of the reinforcing member, and a connecting portion situated between the two hollow mesh porions for connecting the same. The connecting portion has a plurality of tortuous lines to define hollow areas therein, and a marker. Each hollow area is greater than a mesh size of the hollow mesh portions, and the marker is formed in one of the tortuous lines. Thus, a position of the connecting portion is realized at a time of installation of the reinforcing member. After the expandable reinforcing member is expanded, the reinforcing member can be slightly moved to relocate the position.
