  • Publication number: 20080147178
    Abstract: Biocompatible copolymers are manufactured to include a zwitterionic monomer and an alkoxy acrylate monomer. The alkoxy acrylate monomer can be a 2-methoxyethyl methacrylate (MOEMA) or a 2-methoxyethyl methacrylate (EOEMA). Alternatively, the alkoxy acrylate can be 2-methoxyethyl acrylate (MOEA) or 2-ethoxyethyl acrylate (EOEA). The alkoxy acrylate monomers advantageously give the zwitterionic copolymers greater ductility, strength, and toughness while maintaining a desired amount of hydrophilicity. The improved toughness allows the zwitterionic copolymers to be processed without cross-linking, which improves the elongation properties of the zwitterionic copolymer, and reduces the risk of cracking during use.

  • Publication number: 20080124372
    Abstract: The present disclosure teaches methods of controlling the release rate of agents from a polymeric matrix that include designing and creating a predetermined initial morphology (IM) profile in a polymeric matrix. The teachings indicate, inter alia, that control over the release rate of agents can provide for an improved control over the administration of agents as well as have an effect upon the mechanical integrity and absorption rate of the polymeric matrix.

  • Publication number: 20080057101
    Abstract: The present invention is a medical device for controlling the release of an active agent. The medical device has a supporting structure having a porous body disposed therein. At least one elution rate controlling matrix containing an effective amount of at least one active agent is disposed within the pores of the porous body in a manner that protects the matrix from mechanical damage. The medical device may therefore be used for controlled drug release applications. Additionally, the present invention discloses a method for using the medical device for the treatment and prevention of diseases in mammals. This invention further relates to a method for using the medical device for treating and preventing vascular diseases.

  • Publication number: 20070059434
    Abstract: A method of coating an implantable medical device, such as a stent, is disclosed. The method includes applying a formulation on a first polymer layer containing a therapeutic substance to form a second layer. The formulation can contain a highly hydrophobic polymer or a solvent which is a poor solvent for the drug or the polymer of the first layer. The formulation can have a low surface tension value or a high Weber number value.
