ABSTRACT:
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.
