Abstract

A stent for the splinting and/or for the holding open of a hollow organ is comprised from filaments 11 which are formed together into a tubular and self-expanding netting. In the collapsed state the stent 10 is stretched in an axial direction and in an extended state the stent is fore-shortened in the axial direction. The filaments 11 are formed with rectangular cross-section and the crossing-points 12 are securely attached to another at the free ends 14 and 15.
