摘要:
The invention concerns an endovascular implant for the application of an active substance into the media 22 of a blood vessel and two processes for the production thereof. A base body 42 of the implant has at least in portion-wise manner at a surface 40 which is towards the blood vessel, a plurality of microdevices 10 for injection of the active substance. Each microdevice 10 includes on the one hand at least one microcannula 38 which is raised out of the surface 40 of the implant to such an extent that, when the implant bears against a wall 12 of the blood vessel in surface contact, the microcannula penetrates into the media 22 of the blood vessel, and on the other hand at least one active substance deposit 36 which is in communication with at least one microcannula 38.

摘要:
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. In this connection, the inside diameter threshold value preferably amounts to about 75% of a nominal inside diameter, or the compression pressure threshold value preferably amounts to about 0.2 bar.

The invention relates to a medical valve implant (10a-d), in particular a heart valve implant (12a-d), for implantation in an animal body and/or human body, comprising a support frame (14a-d) which has at least one wall (16a-d). It is provided that one region (18a-d) of the at least one wall (16a-d) of the support frame (14a-d) is curable.
