Abstract:
A braided implantable endoprosthesis including:a first number of elongated resilient first members wound helically in a first common direction, and a second number of elongate resilient second members wound in a second common direction different than the first common direction, and braided together with the first members in a braid pattern other than 1-over-1-under, to form a tubular body constrainable to a reduced diameter and self-expandable to an increased diameter, said tubular body having opposite first and second end edges;wherein the first members and the second members form multiple crossing points each comprised of a crossing member pair including a first member and a second member, each member of the pair contacting the other and being free for a limited sliding with respect to the other;wherein the crossing points include control points at which one of the members of the pair supplies sufficient control to the other member of the pair, and non-control pairs at which neither member of the pair supplies sufficient control to the other;a first trim extension including a first series of edge terminae, formed in the first and second members and defining a portion of said first end edge of the tubular body, wherein each of the edge terminae is spaced at a pre-determined distance from its nearest crossing point; anda second trim extension including a second series of terminae of at least one of the first members and the second members, wherein the second trim extension is spaced apart from the first trim extension in an axially inward direction with respect to the tubular body by a depth in said axial direction of at least one pic.
