Claims
- 1. A method for treating prostate disease, chronic urethritis or strictural disease comprising
applying a polymeric material to the walls of the lower urinary tract, cavity or the urethra lining
- 2. The method of claim 1 comprising administering an adhesive polymeric material within the cavity.
- 3. The method of claim 1 comprising administering a polymeric material which provides mechanical or structural support to the prostate or urethra.
- 4. The method of claim 1 wherein the polymeric material has controlled permeability.
- 5. The method of claim 3 wherein the polymeric material forms a lining or support structure within the urethra.
- 6. The method of claim 4 wherein the polymeric material forms a barrier effective to decrease inflammation of the urethra.
- 7. The method of claim 1 wherein the polymeric material further comprises agents selected from the group consisting of prophylactic, diagnostic and therapeutic agents.
- 8. The method of claim 1 further comprising providing a catheter having the polymeric material forming a coating thereon.
- 9. The method of claim 1 wherein the polymeric material is biodegradable.
- 10. The method of claim 1 wherein the polymeric material is applied as a liquid and solidified in situ.
- 11. The method of claim 10 wherein the polymeric material is polymerized in situ.
- 12. The method of claim 1 wherein the polymeric material is configured by conductive heat, resistance heating, radiofrequency heating, microwave heating, electrochemical heating, light absorbance or generation, infrared, fiberoptics, ultrasound or a combination thereof to conform the polymeric material to the tissue surface.
- 14. The method of claim 10 wherein the polymeric material is applied from a catheter.
- 15. The method of claim 14 wherein the polymeric form is polymerized by application of light from the catheter.
- 16. A polymeric form for application to the walls of the lower urinary tract, cavity or the urethra lining using a device having an expandable element to conform the polymeric form to the walls.
- 17. The form of claim 16 wherein the form is a sheet.
- 18. The form of claim 16 where the sheet is a solid, mesh, or porous form.
- 19. The form of claim 16 further comprising regions or structures providing mechanical support or having different mechanical or chemical properties.
- 20. The form of claim 16 further comprising a bioactive agent.
- 21. The form of claim 20 wherein the bioactive agent is selected from the group consisting of hemostatics, antibiotics, chemotherapeutics, antiinflammatories, and cells.
- 22. A catheter system comprising a guide wire, an expandable element to deploy a polymeric form to the walls of the lower urinary tract, cavity or the urethra lining, a polymeric form, and a covering sheath for the expandable element.
