Abstract
An apparatus and method for embedding particles into the polymer matrix of a medical device are disclosed. The apparatus may include an electrostatic spray nozzle adapted to direct a stream of nanoparticles dissolved in a solution toward a positive outlet. A medical device, mounted onto an electrode, can then be placed into or proximate the stream such that upon energization of the electrode, the charged particles are redirected from the outlet toward the electrode. By spacing the electrode and energizing the electrode appropriately, the charged particles can be accelerated to a degree sufficient to cause the charged particles to embed themselves into the polymer matrix of the medical device.
