    • Splittable tubular devices and methods for making them are provided. In one embodiment, a tubular device includes a proximal end, a distal end sized for introduction into a body lumen, and a lumen extending between the proximal and distal ends. The tubular device includes an outer tubular layer defining a circumference; and a reinforcing layer bonded to the outer tubular layer, the reinforcing layer including a circumferential interruption. To make a tubular device, an elongate tubular reinforcing structure may be folded into itself to define first and second longitudinal edges, and rolled until the longitudinal edges are disposed adjacent one another. The reinforcing structure may be attached to a tubular structure such that the longitudinal edges define a circumferential interruption extending along a length of the tubular structure.
    • 提供可分离的管状装置及其制造方法。 在一个实施例中,管状装置包括近端,尺寸适于引入体腔的远端和在近端和远端之间延伸的内腔。 管状装置包括限定圆周的外管层; 以及加强层,其与所述外管层接合,所述加强层包括周向中断。 为了制造管状装置,细长管状加强结构可以折叠成自身以限定第一和第二纵向边缘,并且滚动直到纵向边缘彼此相邻地设置。 加强结构可以附接到管状结构,使得纵向边缘限定沿着管状结构的长度延伸的圆周中断。
