Abstract:
A device for treatment of bodily conduits in an area of a bifurcation where a principal conduit separates into two secondary conduits, the device comprising non-overlapping segments delimiting longitudinal conduits, one of said segments being configured to be engaged in the primary conduit in the area of bifurcation, and another of said segments being configured to be engaged in a secondary conduit of the bifurcation;at least one radially expandable first said segment having, in a predetermined expanded state, a cross section substantially greater than a cross section of one of the secondary conduits; at least one radially expandable second said segment having a first end and a second end, said first end being capable of expanding to a greater diameter than said second end, and having in a predetermined expanded state, a truncated shape, conforming to a shape of the bifurcation in the area of a widened transitional zone that separates the principal conduit from the secondary conduits; and a flexible link extending between and being separately connected to at least one of said first segment and said first end of said second segment, permitting said segments to be oriented in relation to one another on the basis of the orientation of the secondary conduit, which receives said first segment, in relation to said widened transitional zone, wherein said second segment has an axis not coincident with a longitudinal axis of said first segment, but oblique in relation to the axis of said first segment, in order to be adapted optimally to the anatomy of the bifurcation which is to be treated; wherein the cross section of said first segment in the predetermined expanded state is less than the cross section of the first and second ends of said second segment when the second segment is in its predetermined expanded state.
