An erodible prosthesis having two or more different erosion rates is disclosed. These different erosion rates can be selectively initiated. In the embodiment according to the present invention, as an agent for initiating the erosion rate, for example, a sensitizer, a dissolution inhibitor, a photoacid generator, a biochemically active additive, a thermally active catalyst, a photoactive catalyst, electromagnetic radiation An active catalyst, hydration active catalyst, pH active catalyst, low melting point drug and / or enzyme active catalyst can be included. These agents can be dispersed in one or more layers. |
