<p>A stent for expanding lumens, formed of a wire member (8) which has a zigzag configuration comprising a series of first and second straight sections (7,17) joined by a plurality of bends which are cross-linked with each other to form a plurality of turns. The stent need not provide means for connecting wire members, and the elasticity of the stent is uniform. The position of the stent in a body cavity is maintained since any longitudinal change of the stent is very small. Also the stent provides means for preventing restenosis of the lumens. <IMAGE></p> |
