A stent for placement in a body tube includes a flexible support structure composed of an elastomer which is hard in a temperature range lower than 25 DEG C. and soft in a temperature range greater 35 DEG C. The flexible support structure may be embedded in a hollow cylindrical casing of an elastic synthetic material which has a limited elasticity at least at body temperature, wherein the casing is composed of an elastomer which is hard in a temperature range lower than 25 DEG C. and soft in a temperature range greater than 35 DEG C. The casing in which the flexible support structure is embedded may also be of a memory elastomer, particularly on the basis of polyurethane. |
