A　detailed　study　of　the　microstructural　features　in　Nitinol　stents　was　performed,　which　included　TEM　examination　to　determine　the　grain　structure　evolution　during　stent　processing.　The　samples　were　extracted　from　the　surface　of　pre-laser　cut　tubes,　laser　cut　vascular　stents,　and　electropolished　stents.　A　Focused　Ion　Beam　(FIB)　was　used　for　preparation　of　TEM　samples.　The　analysis　has　shown　that　the　laser　cutting　process　dramatically　changes　the　surface　microstructure　of　the　stent　by　producing　a　Heat　Affected　Zone.　However,　in　the　case　of　the　stents　analyzed　here,　the　electropolishing　procedure　adequately　removed　the　Heat　Affected　Zone　completely.　Characterization　of　the　main　morphologic　features　of　the　material　was　based　on　TEM　imaging,　and　the　effect　of　the　different　processing　steps　on　the　crystallographic　texture　was　determined　by　adequate　selection　of　different　sample　locations.
