BACKGROUND:　Braided　stents,　such　as　Pipeline　Embolization　Device　(PED;　ev3　Neurovascular,　Irvine,　CA,　USA),　are　commonly　used　to　treat　cerebral　aneurysms.　However,　little　information　is　available　on　the　compression　and　bending　characteristics　of　such　stents.　OBJECTIVE:　This　paper　investigates　how　geometrical　parameters　of　braided　stents　influence　their　radial　compression　and　bending　characteristics.　METHODS:　Six　groups　of　braided　stent　models　with　different　braiding　angles,　numbers　of　wires　and　wire　diameters　are　constructed.　Parametric　analyses　of　these　models　are　conducted　using　Abaqus/Explicit　software.　The　numerical　results　of　a　finite　element　analysis　are　validated　by　comparison　with　data　of　theoretical　analysis.　RESULTS:　The　results　show　that　the　radial　stiffness　is　not　uniform　along　the　longitudinal　direction　of　the　stent.　When　the　braiding　angle　increases　from　30　degrees　to　75　degrees,　the　minimum　radial　deformation　decreases　from　0.85　mm　to　0.0325　mm　(at　a　pressure　of　500　Pa,　for　24　braided　wires).　When　the　wire　diameter　increases　from　0.026　mm　to　0.052　mm,　the　minimum　radial　deformation　decreases　from　0.65　mm　to　0.055　mm　(at　a　pressure　of　500　Pa　and　a　braiding　angle　of　60　degrees,　for　24　braided　wires).　Frictions　don＇t　affect　stent　diameter　and　its　axial　length　when　braided　stent　is　crimping,　but　the　friction　must　be　considered　when　it　is　related　to　the　radial　pressure　required　for　compression　the　braided　stent.　CONCLUSIONS:　Compared　with　commonly　used　intracranial　stents,　a　braided　stent　with　geometrical　parameters　close　to　PED　stent　has　a　smaller　radial　stiffness　but　a　considerably　greater　longitudinal　flexibility.　The　results　of　this　analysis　of　braided　stents　can　help　in　the　design　and　selection　of　flow　diverter　stents　for　clinical　treatment　of　cerebral　aneurysms.
