ABSTRACT:
In an inventive stent (10), helical filaments (12, 13) are disposed on a first tubular layer (11). The helical filaments (12, 13) are mutually phase-shifted such that they do not touch and lie in one plane. The helical filaments (12, 13) are completely coated by a second elastic tubular polymer layer (14) which is connected to the first elastic tubular layer (11). Further helical filaments may be disposed on the second elastic tubular layer (14). The inventive stent can be lengthened for introduction into a hollow organ and is self-expanding.
