Abstract:
The present invention provides insertable medical devices having elastic surfaces associated with bioactive agent-containing microparticulates and a coating material. Upon expansion of the elastic surfaces the microparticulates can be released to a subject.

Claim (Index 1):
An insertable medical device to deliver a bioactive agent to tissue of a subject, the device comprising:\n (a) an expandable elastic portion, (b) a flexible biostable hydrogel matrix layer selected from the group consisting of poly(acrylamide), poly(methacrylamide), poly(vinylpyrrolidone), poly(acrylic acid), poly (ethylene glycol), poly(vinyl alcohol), poly(2-hydroxy-ethyl methacrylate), methyl vinyl ether/maleic anhydride copolymers, and vinyl pyrrolidone/methacrylamide copolymers, wherein the flexible biostable hydrogel matrix forms a coating on an outer surface of the expandable elastic portion, (c) a biodegradable layer, and (d) microparticulates having an average greatest dimension in the range of 0.1-10 microns associated with (i) a surface of the flexible biostable hydrogel matrix, (ii) a surface of the biodegradable layer, or (iii) both surfaces of the flexible biostable hydrogel matrix and the biodegradable layer; wherein the microparticulates comprise a water-insoluble bioactive agent and contact the tissue upon expansion of the elastic portion.
