    摘要： Stents having a plurality of serpentine bands including a proximal end portion, a distal end portion, and a middle portion therebetween are herein disclosed. Each of the bands includes peaks and valleys. Serpentine bands of the proximal end portion are connected together in a repeating pattern of connected and unconnected peaks and valleys. Serpentine bands of the distal end portion are connected together in a repeating pattern of connected and unconnected peaks and valleys. The repeating pattern of the proximal end portion is different than the repeating pattern of the distal end portion.

    摘要： A stent delivery system is disclosed that has an outer assembly and an inner assembly that accommodates a stent. The inner assembly further has an external assembly contact area projecting from its surface that frictionally contacts an inner surface of the outer assembly. The contact area is positioned at one end of the inner assembly, proximal to the stent accommodating area. Also disclosed is a method of using the stent delivery system.

    摘要： An endoprosthesis comprises a plurality of serpentine bands. Each serpentine band comprises a plurality of interconnected struts forming peaks and troughs. Adjacent serpentine bands are interconnected by one or more connectors. First and second serpentine bands are connected via at least one connector. The connector has a first side facing one the struts and a second side facing another of the struts. The connector extends from an inside of a trough of the first serpentine bands to the outside of a trough of the other of the serpentine bands. The connector has a first bump extending from the first side and a second bump extending from the second side opposite the first, the first bump located adjacent a first peak and the second bump located adjacent a second peak.

    摘要： A prosthesis delivery and deployment device includes an elongate and flexible outer catheter. The outer catheter has a tubular wall of layered construction, including a translucent inner liner running the complete catheter length, and three outer layers including a translucent distal layer, an opaque medial layer and an opaque proximal outer layer. The outer layers are adjacent one another and are bonded to the liner. A braid composed of helically wound metal filaments is disposed between the liner and the proximal and medial outer layers, and includes a distal portion between the liner and a proximal portion of the distal outer layer. The liner and distal outer layer provide a translucent distal region of the catheter that is adapted to constrain a radially self-expanding prosthesis in a radially reduced, axially elongated state. Because the stent constraining region is translucent, an endoscope can be used to visually monitor the stent when so constrained. Radiopaque markers can be mounted to the outer catheter and to an inner catheter used to deploy the prosthesis, to afford a combined visual and fluoroscopic monitoring for enhanced accuracy in positioning the prosthesis, both before and during its deployment.

    摘要翻译： 假体递送和展开装置包括细长且柔性的外导管。 外导管具有分层结构的管状壁，其包括运行完整导管长度的半透明内衬，以及包括半透明远侧层，不透明中间层和不透明近侧外层的三个外层。 外层彼此相邻并且结合到衬垫上。 由螺旋缠绕的金属细丝构成的编织物设置在衬垫和近侧和内侧外层之间，并且包括位于衬垫和远端外层的近侧部分之间的远侧部分。 衬垫和远端外层提供导管的半透明远侧区域，其适于以径向减小的轴向伸长状态约束径向自扩张假体。 由于支架约束区域是半透明的，所以当受到限制时，可以使用内窥镜来视觉监测支架。 不透射线的标记物可以安装到外导管和用于部署假体的内导管，以在组装之前和期间提供组合的视觉和荧光透视监测，以提高假体定位的准确性。
