Abstract: front page image
(EN)A method includes: providing a substrate, depositing a ceramic and an extractable material onto the substrate, forming a porous structure in the ceramic by removing the extractable material, and utilizing the ceramic in an endoprosthesis. An endoprosthesis, such as a stent, including a coating formed of a ceramic and an extractable material that can be removed from the coating to form voids is also disclosed.
