Abstract
Surface coatings including microparticles immobilized in a matrix of polymeric material on a substrate are described. The microparticles can also include an agent which can be useful for various applications, such as medical applications. This invention relates to the field of surface coatings for use in various applications. More particularly, the invention relates to surface coating useful for drug delivery, imaging and other uses of microparticles immobilized via a polymeric matrix.
Claims16
An implantable medical device comprising:
- a) a surface;
- b) a matrix comprising polymeric material, the matrix polymeric material comprising a hydrophobic polymer, copolymer or combinations thereof, and one or more photoreative groups covalently attached to the matrix polymeric material, and wherein the matrix polymeric material is covalently attached to the surface by the photoreactive groups;
- and
- c) a plurality of microparticles immobilized in the matrix of polymeric material, wherein the microparticles comprise a biologically active agent, and the microparticles are 100 nm to 20 μm in diameter, and wherein the biologically active agent is released from the matrix in the presence of a fluid-containing environment.
