Abstract
A stent shaped as a three-dimensional body which is formed by interlaced threads (1) arranged in multistart turns of a helical line. The threads (1) are arranged in at least two groups (2 and 3) of the helical turns featuring opposite senses of helix. The stent ends are established by sections (5) where the turns of one helical line merge into those of the other helical line, said sections appearing as a single length of the thread (1).
Claims11
A stent shaped as a three-dimensional body whose surface is formed by at least two groups of turns (2 and 3) made of interlaced elastic threads and arranged along helical lines having opposite senses of helix, and the end faces of said three-dimensional body are formed by sections (5) where the turns of one helical line pass into the turns of the other helical line, CHARACTERIZED in that each of said sections of passing the turns of the helical lines is formed by a bend of a segment of a single elastic thread (1) from which the turns of helical lines are made.
