IMPROVED PROCESS FOR COATING A MEDICAL DEVICE

摘要

An improved process for electrostatically coating a medical device is described. Temporary conductivity is induced into the surface of a medical device whose surface is normally non-conductive. After inducing temporary conductivity to the surface of the device, it is electrostatically coated either through liquid formulation spray coating or through dry powder deposition. The process provides a high degree of uniformity and control over the coating such that the fine features of the device that are necessary for device function are carefully maintained after the coating is applied.
