Abstract

The present invention provides methods for treating or preventing diseases associated with body passageways, comprising the step of delivering to an external portion of the body passageway a therapeutic agent. Representative examples of therapeutic agents include anti-angiogenic factors, anti-proliferative agents, anti-inflammatory agents, and antibiotics.

Claims

1. A method for treating or preventing vascular diseases associated with body passageways, comprising delivering to an external portion of the body passageway a composition comprising paclitaxel, or an analogue or derivative thereof.

3. The method according to claim 1 or 2 wherein the composition further comprises a polymer.

4. The method according to claim 3 wherein the polymer comprises microspheres having an average size ranging from about 0.5 mm to 200 mm.

5. The method according to claim 3 wherein the polymer is a copolymer of lactic acid and glycolic acid.

6. The method according to claim 3 wherein the polymer is poly (caprolactone).

7. The method according to claim 3 wherein the polymer is poly (lactic acid).

8. The method according to claim 3 wherein the polymer is a copolymer of poly (lactic acid) and poly (caprolactone).

9. The method according to claim 3 wherein the polymer is poly(ethylene-vinyl acetate).

10. The method according to claim 3 wherein the polymer is gelatin.

11. The method according to claim 1 wherein the body passageway is selected from the group consisting of arteries, the esophagus, the stomach, the duodenum, the small intestine, the large intestine, biliary tracts, the ureter, the bladder, the urethra, lacrimal ducts, the trachea, bronchi, bronchiole, nasal airways, eustachian tubes, the external auditory canal, and fallopian tubes.

12. The method according to claim 11 wherein the composition is delivered to an artery via an outer wall of the artery into an adventia.

13. The method according to claim 1 or 2 wherein the vascular disease is stenosis.

14. The method according to claim 1 or 2 wherein the vascular disease is restenosis.

2. A method for treating or preventing vascualr diseases associated with body passageways, comprising delivering via an adventia to smooth muscle cells of the body passageway a composition comprising paclitaxel, or an analogue or derivative thereof.
