Abstract
The present invention provides, in a first aspect a bifurcated stent for use in juxtaposition with an angelogical bifurcation. The bifurcated stent comprises a proximal portion adapted to be disposed within a blood vessel in juxtaposition with a bifurcation, a first distal stent portion adapted to extend across the bifurcation into one of the branched blood vessels, and a second distal stent portion adapted to allow blood to flow from the proximal portion into the other branch blood vessel. The invention also embraces a bifurcated prosthesis including such a bifurcated stent and a tubular graft layer formed from a biocompatible fabric in juxtaposition with the stent. In a second aspect of the invention there is provided a stent connection for joining two stents one to the other to define a continuous lumen through the two stents. Said stent connection comprises a first stent including a male engaging portion which can be compressed radially inwardly and a second stent including a female cooperating portion. Said male engaging portion can be entered into the female cooperating portion in a radially compressed state and thereafter caused or allowed to expand in the female cooperating…
