Application Number:	10/206,853
Patent Claims:	1. A device for intracorporeal use, the device comprising: a structure; and at least one source of at least one therapeutic capable agent associated with the structure, the at least one therapeutic capable agent having a textured surface wherein the surface has peaks and valleys with a distance between the peaks ranging from about 5 .mu.m to about 50 .mu.m. 2. A device as in claim 1, wherein the distance between the peaks is a mean distance. 3. A device as in claim 1, wherein the surface has a peak height ranging from about 0.01 .mu.m to about 10 .mu.m. 4. A device as in claim 1, wherein the surface has a peak height ranging from about 0.05 .mu.m to about 1.5 .mu.m. 5. A device as in claim 1, wherein the surface has a peak height ranging from about 0.1 .mu.m to about 1 .mu.m. 6. A device as in claim 3, 4, or 5, wherein the peak height is an average peak height. 7. A device as in claim 1, wherein the therapeutic capable agent forms a layer having a thickness ranging from about 0.1 .mu.m to about 20 .mu.m. 8. A device as in claim 1, wherein the therapeutic capable agent forms a layer having a thickness ranging from about 0.5 .mu.m to about 7.5 .mu.m. 9. A device as in claim 1, wherein the therapeutic capable agent forms a layer having a thickness ranging from about 1.0 .mu.m to about 5 .mu.m. 10. A device as in claim 7, 8, or 9, wherein the layer thickness is an average thickness. 11. A device as in claim 1, wherein the textured therapeutic capable agent surface forms the outer most layer of the device. 12. A device as in claim 1, wherein the therapeutic capable agent is selected from the group consisting of immunosuppressants, anti-inflammatories, anti-proliferatives, anti-migratory agents, anti-fibrotic agents, proapoptotics, vasodilators, calcium channel blockers, anti-neoplastics, anti-cancer agents, antibodies, anti-thrombotic agents, anti-platelet agents, IIb/IIIa agents, antiviral agents, mTOR (mammalian target of rapamycin) inhibitors, non-immunosuppressant agents, and combinations thereof. 13.
