Document Type and Number:
WIPO Patent Application WO2000044309
Kind Code:
A3
Abstract:
Bifurcated and trifurcated woven stents (10) for insertion and delivery into a variety of anatomical structures, including the aortic-iliac bifurcation, the superior vena cava junction, and the inferior vena cava junction. The bifurcated stents (10) includes a first leg (30) formed from a first plurality of wires, a second leg (30) formed from a second plurality of wires (40), and a common body formed from the first and second pluralities of wires (40). The wires may be nitinol. Biodegradable filaments may also be utilized. The angles created between the crossed wires is preferably obtuse. The bifurcated stents (10) may be formed from as few as two wires. The stents may be formed using plain weaving effected either by hand or by machine.
