ABSTRACT:
A stent has a plurality of wavy annular members each formed of a narrow wavy element and arranged in the axial direction thereof; and a plurality of connection portions each connecting the adjacent wavy annular members to each other axially. The connection portion located in the vicinity of the axial center of the stent is weaker than other constituent parts of the stent and can be broken. That is, an inflating balloon catheter can be inserted into the stent such that the inflating balloon catheter penetrates through a side wall of the stent from its interior after the stent dilates radially. The connection portion can be broken by inflation of the balloon of the inflating balloon catheter.
