发明名称 Stent having flexibly connected adjacent stent elements
摘要 An open stent (a stent having open space through its thickness at locations between the ends of the stent), incorporating flexible, preferably polymeric, connecting elements into the stent wherein these elements connect adjacent, spaced-apart stent elements. Preferably the spaced-apart adjacent stent elements are the result of forming the stent from a helically wound serpentine wire having space provided between adjacent windings. Other stent forms such as multiple, individual spaced-apart ring-shaped or interconnected stent elements may also be used. The connecting elements are preferably longitudinally oriented.

主权项 1. An implantable stent defining a length and having a deployed diameter suitable for implantation and a compacted diameter suitable for passage of the stent through a body conduit, the deployed diameter being larger than the compacted diameter of the stent, the implantable stent comprising adjacent metallic stent elements spaced apart longitudinally wherein the adjacent stent elements are connected longitudinally only by a perforated polymeric non-woven sheet cover, the cover having a multiplicity of individual apertures of substantially uniform size, each of the multiplicity of individual apertures having a long dimension that is parallel to the longitudinal axis of the stent when the stent is at the compacted diameter, each of the multiplicity of individual apertures having a substantially uniform shape when the stent is at the deployed diameter, wherein the multiplicity of individual apertures have a minimum size of about 0.10 mm; and wherein the stent is substantially open, having a porosity index of at least 50% along the length of the stent when the implantable stent is at the deployed diameter.
