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 19):
An insertable medical device comprising an angioplasty balloon capable of delivering a bioactive agent to tissue of a subject, the device comprising:\n (i) an expandable elastic balloon portion; (ii) a flexible biostable hydrogel matrix 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 coated on an outer surface of the expandable elastic balloon portion, the matrix further comprising a polymer having pendent reacted arylketone photogroups that covalently bond the polymer to a target selected from other polymers in the flexible biostable hydrogel matrix and a coated surface of the expandable elastic portion, wherein the flexible bio stable hydrogel matrix forms a non-contiguous coating on the outer surface of the expandable elastic portion; (iii) a biodegradable layer on the outer surface of the flexible biostable hydrogel matrix; and (iv) microparticulates associated with the flexible biostable hydrogel matrix and biodegradable layer that disassociate from the elastic balloon portion during expansion.
