NANOPARTICLE AND SURFACE-MODIFIED PARTICULATE COATINGS, COATED BALLOONS, AND METHODS THEREFORE |
摘要 |
<p>Devices, coatings, and methods therefore comprise a medical device for delivering nanoparticles of an active agent to a treatment site. A coating on the medical device comprises active agent nanoparticles, which delivers coating to the treatment site and releases active agent nanoparticles into the treatment site over at least one day. A coating may comprise a polymer, a surfactant, and the nanoparticles. The coating may be prepared by forming a nanoemulsion. A coating may comprise encapsulated active agent nanoparticles which comprise active agent nanoparticles encapsulated in a polymer. The coating may have a positive surface charge. The coating may deliver active agent nanoparticles into the treatment site over at least about one day. The coating may be formed of a surfactant and nanoparticles mixture. The active agent nanoparticles may be deposited on the medical device using electrostatic capture.</p> |
