ABSTRACT:
An endoluminal stent is formed in a modular construction to include at least one elongate spine and a plurality of general tube-defining modules attached to the spine, or spines, in a longitudinal array. The modules are constructed along a spine-like structure so as to form a bifurcate shape for implantation in branching or bifurcating vessels. Each module defines, in cooperation with a spine, a closed ring-like structure. Each of the modules is radially expandable from a reduced diameter, low profile configuration, in which it is readily navigated through the body passages, to an expanded diameter engageable with the inner luminal surface of the body lumen. The stent, being of modular construction, can be built to individual specifications for a specific patient. Modules are formed from a wire shaped in a flat serpentine configuration that is then wrapped in a cylindrical configuration with its free ends connected to a spine. The modules are expandable, as by a balloon, from a low profile to an expanded configuration. During expansion, the modules can wipe against the inner surface of the lumen to smooth sharp points or edges. A spine of the stent defines a substantially greater mass than that of the individual modules such that the spine can be readily observed under X-ray or fluoroscopy. The modular construction enables a wide range of variation in the characteristics of the stent, including longitudinal flexibility, radial expansion characteristics, among others.
