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 20):
A method for delivering a bioactive agent to tissue of a subject comprising the steps of:\n 1) providing an insertable medical device comprising: (a) an expandable elastic portion, (b) a flexible biostable hydrogel matrix layer selected from the group consisting of poly(acrylamide), poly(methacrylamide), poly(vinyl pyrrolidone), 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; 2) inserting the medical device into a subject; and 3) expanding the expandable elastic portion in the subject, wherein the microparticulates disassociate from the medical device and are released into the subject, and wherein bioactive agent is released from the microparticulates to provide a therapeutic effect to the tissue of the subject.
