  • Methods for Coating Medical Devices
    Publication number: 20130156935
    Abstract: Processes for coating medical devices are provided herein. The processes include heating a surface of the particles used to form the coating as the particles are being applied to the medical device. The resulting coating has improved adherence to the medical device, and does not require the use of solvents and/or water, obviating the need for any steps that otherwise might be required to remove these solvents and/or water. Sufficient adherence of the particles to the medical device may also occur without the need for heating the substrate used to form the medical device.
