Abstract

The invention relates to a stent which can be expanded and transformed from a first state, wherein the inner diameter is narrow, into a second state wherein said diameter is larger and areas devoid of material border on other material elements, in order to define therewith a general stent surface from which elements with material protrude in sections in an expanded state. According to the invention, a first series of sections are provided in order to protrude from the covering surface of the stent in an implanted state in the direction of flow.A second series of sections are also provided in order to protrude from the covering surface of the stent in the direction of a counterflow in an implanted state.
