    Abstract: An implant having a coating comprising a polymer matrix is swollen in a pharmaceutical solution whereby pharmaceutically active compound is imbibed into the polymer matrix. When the product is implanted, release of the pharmaceutically active compound from the coating takes place. The polymer is preferably formed from ethylenically unsaturated monomers including a zwitterionic monomer, most preferably 2-methacryloyloxyethyl-2?-trimethylammoniumethyl-phosphate inner salt. The monomers from which the polymer is formed may further include surface binding monomers, such as hydrophobic group containing monomers, and crosslinkable monomers, the content of which may be used to control the swellability. Preferably the implant is a stent and the coating of polymer on the exterior wall surface is thicker than the coating of polymer on the interior surface. Release of the drug may be controlled by selection of comonomers. The implant is suitably a stent for use in the cardiovascular system.

The high molecular weight polymer may be micronized prior to its suspension in the liquid carrier. Once suspended, the liquid is introduced into a spray coating machine such as a partially or fully perforated pan system wherein the tablets are coated as desired.

  • Patent number: 7632533
    Abstract: A method for depositing controlled quantity of particles on a substrate comprises providing aerosolized particles in a deposition zone having first and second electrodes, and creating an electrostatic field between the first electrode and the second electrode to create a pool of ions at the first electrode, charging particles within the deposition zone with the ions, and moving the particles towards and depositing the particles onto the substrate. In order to prevent excessive charge build up on the substrate, the electrostatic field is periodically reversed.
