A　detailed　study　of　the　microstructural　features　in　Ni-Ti　stents　was　performed,　which　included　TEM　examination　to　determine　the　grain　structure　and　precipitation　kinetics　after　heat　treatment　of　the　stent　tube.　The　samples　were　extracted　from　vascular　stents,　as　well　as　from　the　tubes　used　in　early　stages　of　the　production　process.　The　Focused　Ion　Beam　(FIB)　equipment　was　used　for　preparation　of　TEM　samples.　The　specimens　were　analyzed　at　different　stages　of　the　stent　production　process,　such　as　laser　cutting　and　shape　setting,　and　correlations　between　the　microstructure　and　the　manufacturing　process　were　established.　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.
