Abstract
The present invention is directed to methods, processes, and systems for delivering therapeutic agent to a medical device. Under some methods, processes, and systems of the invention, particles including a magnetic material and a therapeutic agent may be directed towards a medical device via magnetic attraction. In another embodiment particles including a magnetic material may force a therapeutic agent/solvent solution into porous matrix by using a magnetic attraction. In still another embodiment, a medical device having at least a portion thereof including a magnetic material is used to attract and adhere particles comprising magnetic material and therapeutic agent to a target surface of the medical device, wherein the particles are fused to the target surface.
