Method for etching a micropatterned microdepot prosthesis

摘要: An implantable prosthesis, for example a stent, is provided having one or more micropatterned microdepots formed in the stent. Depots are prosthesis via chemical etching and laser fabrication methods, including combinations thereof. They at preselected locations on body of have depth, size, shape. The depots can various shapes cylindrical, conical an inverted-conical Substances such as therapeutic substances, polymeric materials, materials containing radioactive isotopes, radiopaque be deposited into depots.
