Abstract: A 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 typically web-shaped and result from creating slits or apertures in a covering of graft material applied to the stent and then, for example, applying heat to cause the slits or apertures to enlarge. The remaining graft material forms the interconnecting webs between the adjacent stent elements.

Abstract: A diametrically adjustable endoprosthesis includes a controlled expansion element extending along at least a portion of a graft and is supported by a stent. The controlled expansion element diametrically constrains and limits expansion of the endoprosthesis. Upon deployment from a smaller, delivery configuration, the endoprosthesis can expand to the initial diameter set by the controlled expansion element. Thereafter, the endoprosthesis can be further diametrically expanded (e.g., using balloon dilation) by mechanically altering the controlled expansion element.

Abstract: An endoluminal device comprises a tubular member and a reinforcement member that is separable from, or together with, a wall of the tubular member, and removable in-situ.
