Stent, system and method for gastrointestinal tract treatment

The present invention generally relates to stents, systems, and methods for gastrointestinal therapy. In some embodiments, a stent may include a tubular scaffold having opposing first and second ends with a lumen extending between the first and second ends. The tubular stent may include a flared section and an intermediate section extending from the flared section, wherein a first diameter of the flared section is greater than a second diameter of the intermediate section. The stent may also include a liner extending partially along a surface of the tubular scaffold, wherein the liner is spaced from an anchoring region of the flaring section to promote tissue ingrowth with the flaring section. 本发明总体上涉及用于胃肠治疗的支架、系统和方法。在一些实施例中，支架可以包括管状骨架，其具有相对的第一端和第二端，其中腔在所述第一端和第二端之间延伸。所述管状支架可以包括扩口部段和从所述扩口部段延伸的中间部段，其中所述扩口部段的第一直径大于所述中间部段的第二直径。所述支架还可以包括部分地沿着所述管状骨架的表面延伸的衬里，其中所述衬里与所述扩口部段的锚固区域间隔开以促进与所述扩口部段的组织向内生长。
