  • Stent for expanding a lumen
    Patent number: 5545211
    Abstract: A stent for expanding lumens, formed of a wire member which has a zigzag configuration, first and second straight sections and a plurality of bends cross-linked with each other to form a plurality of turns. The stent need not provide means for connecting each wire member. The elasticity of the stent is uniform. The position of the stent in a body cavity is maintained since the longitudinal change of the stent is very small. Also the stent provides means for preventing restenosis of the lumens.
