Abstract: A balloon catheter comprising a body and first and second arms attached to one end of the body. A common inflation lumen extends along the body and branches into each of the arms. An expandable balloon is provided on each arm so as to be in fluid communication with the lumen of each arm. The catheter further includes a guide wire lumen in each of the arms. A method for dilating a narrowed bifurcated vessel is also disclosed.

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.
