Abstract:
1. A method of manufacturing a stent implantable within a body vessel of a human subject, comprising: providing a tubular member having a diameter corresponding to a compressed condition, the tubular member having opposite ends, namely a proximal end and a distal end; forming a plurality of substantially parallelogrammic body cells and flare cells in the tubular member, wherein each body cell is defined by a pair of parallel long body cell struts intersecting a pair of parallel short body cell struts, each flare cell is defined by a pair of parallel long flare cell struts intersecting a pair of parallel short flare cell struts; said forming includes selecting an elongation ratio of each flare cell, the flare cell elongation ratio being a ratio of long flare cell strut length to short flare cell strut length that is substantially greater than an elongation ratio of each body cell, the body cell elongation ratio being a ratio of long body cell strut length to short body cell strut length; and said forming includes positioning a plurality of the flare cells at said opposite ends.
