Wire-tubular hybrid stent

摘要: Radially-expandable stents are provided with improved longitudinal flexibility and stability, torsional trackability conformability, hoop strength. The combine the advantages typically associated wire those stability. include a plurality of cylindrical sections successively arranged along axis stent, W-shaped elements in each sections, having center section two outside legs, opening alternating directions wherein adjacent alternate between pairs that open towards other away from when moving about circumference sections; tie members connecting pair sections. Methods implanting body lumens also disclosed.
