Stent

摘要

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 ).
