An artificial respiration bag (10) comprises an inflatable sidewardly folded reservoir (11). A holding element (12) and a support (15) forming a lumen opening (16) and connected to a cuff (13) are provided for on the reservoir. The entire artificial respiration bag (10) is produced from a silicone or thermoplastic elastomer. In this manner, the artificial respiration bag (10) is manufactured from a material to which the skin is insensitive and which does not cause allergic reactions. The holding element (12) has an integrally vulcanized holding ring (12'). The support (15) has a surrounding enlargement (20) which engages a shoulder (19) of the cuff and is permanently attached thereto. In this manner, the artificial respiration bag (10) fulfills the strength and safety requirements of ISO-standard 5362.

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.
