  • Medical assembly suitable for long-term implantation and method for fabricating the same
    Patent number: 7947378
    Abstract: A process for fabricating a medical assembly having a medical device at least a portion of which is formed of inorganic material is provided. The medical assembly is suitable for substantially long-term implantation in a host animal. The process includes modifying a surface of the medical device to form a hydrophilic adhesion-promoting surface. The hydrophilic adhesion-promoting surface is coated with an alginate solution comprising alginate and the alginate is reacted with alkaline earth metal cations.
    Type: Grant

  • Demetallization of polymer/metal multilayer films by etching
    Patent number: 5716532
    Abstract: A method of improving the breakdown strength of polymer multi-layer (PML) capacitors is provided. The method comprises removing metal, specifically, aluminum, from the cut edge. This is done by either etching back the metal electrode layers in either basic or acidic solution or by anodizing the metal to cover that portion of the metal at the edge with an oxide. Removing the metal from the cut edge increases the breakdown strength of the PML capacitors by a factor of two or more.
