Abstract

An active agent delivery system comprising a nanofiber web and an active agent carried by the nanofiber web.

Claims (22)

1 . An active agent delivery system comprising a nanofiber web and an active agent carried by the nanofiber web.

2 . An active agent delivery system according to claim 1 wherein the nanofiber web comprises a non-woven structure.

3 . An active agent delivery system according to claim 2 wherein the non-woven structure has a thickness of less than 10 mm.

4 . An active agent delivery system according to claim 2 wherein the non-woven structure has a thickness of less than 5 mm.

5 . An active agent delivery system according to claim 2 wherein the non-woven structure has a thickness of less than 1 mm.

6 . An active agent delivery system according to claim 2 wherein the nanofiber web comprises polymeric nanofibers.

7 . An active agent delivery system according to claim 6 wherein the polymeric nanofibers are biodegradable.

8 . An active agent delivery system according to claim 6 wherein the polymeric nanofibers are non-biodegradable.

9 . An active agent delivery system according to claim 6 wherein the polymeric nanofibers are configured to become a gel when wet by bodily fluids.

10 . An active agent delivery system according to claim 6 wherein the polymeric nanofibers are formed out of a polymer selected from the group consisting of poly-(lactide) (PLA), polycaprolactone, poly-(vinyl alcohol), biodegradable polyester, chitosan, poly-(propylene carbonate), and poly-(lactide-glycolide), poly-e-caprolactone, poly-trimethylene carbonate, poly-glycolide, poly-p-dioxanone.

11 . An active agent delivery system according to claim 10 wherein the polymer may be a homopolymer, a copolymer or a multimer.

12 . An active agent delivery system according to claim 6 wherein the polymeric nanofibers have a diameter of less than 3 micrometers.

13 . An active agent delivery system according to claim 6 wherein the polymeric nanofibers have a diameter of less than 500 nanometers.

14 . An active agent delivery system according to claim 6 wherein the polymeric nanofibers have a diameter of greater than 2 nanometers and less than 500 nanometers.

15 . An active agent delivery system according to claim 2 wherein the active agent is disposed in openings in the non-woven structure.

16 . An active agent delivery system according to claim 6 wherein the active agent is disposed on the surface of the polymeric nanofibers.

17 . An active agent delivery system according to claim 6 wherein the active agent is incorporated in the side-walls of the polymeric nanofibers.

18 . An active agent delivery system according to claim 1 wherein the active agent comprises an antimicrobial.

19 . An active agent delivery system according to claim 18 wherein the antimicrobial comprises taurolidine.

20 . A method for delivering an active agent to a patient, the method comprising:

providing an active agent delivery system comprising a nanofiber web and an active agent carried by the nanofiber web; and

positioning the active agent delivery system into or onto the body of a patient.
