<p><P>PROBLEM TO BE SOLVED: To provide a serpentine coiled ladder stent, formed by a strip cell where a coil is wound, and making the side of the cell serpentine. <P>SOLUTION: The stent 30 is constructed by a strip helically wound into a series of coiled windings 31, and is formed of at least two side bands 34, 35 connected to each other, for example by a series of cross struts 36. Each side band is formed in a serpentine pattern including a series of bends 38, wherein upon expansion of the stent, the bends 38 of the side bands 34, 35 open to increase the length of each of the individual cells 37 in the helical direction, thereby lengthening the strip in the helical direction to allow the stent 30 to expand without any significant unwinding of the strip. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
