  • Publication number: 20110190869
    Abstract: An endoprosthesis, particularly an intraluminal endoprosthesis, having a basic structure that is preferably configured in the shape of a hollow cylinder, preferably configured as a basic lattice. In the expanded state, an inner volume enclosed by the basic structure can be changed by means of the elasticity of the basic structure, where the basic structure can assume a normal state and a state of significant compression, with regard to its compression behavior, for further improvement of the healing progression when using an endoprosthesis according to the invention, where in the state of significant compression, the elasticity of the basic structure is significantly reduced as compared with the elasticity in the normal state. The state of significant compression is characterized by the fact that an inside diameter threshold value of the basic structure is not reached, or that a compression pressure threshold value is exceeded.
