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.

摘要： The invention is directed to a process and apparatus for preparing coated particles, in particular a process for preparing particles that are coated with small particles using electrospraying. The coated particles produced according to the present invention find use for instance as catalysts or as pharmaceuticals. According to the invention a host particle is contacted in a gas stream where it is allowed to contact with one or more moving tribocharging particles, thus providing a charged host particle, which is subsequently contacted with charged guest particles in an electrospraying step.
