Abstract

Implantable medical devices include a substrate having applied thereto a coating including a polymeric material possessing a core and at least one functional group known to have click reactivity.

Claims

1. A method of producing a medical device comprising:

applying a coating composition including a natural polymer possessing a core and at least one functional group known to have click reactivity to a polymeric textile, whereby the coating composition imparts an activated surface to the textile via the functional group having click reactivity and the natural polymer is selected from the group consisting of chitosan, collagen, hyaluronic acid, polysaccharides and copolymers and combinations thereof.

2. The method according to claim 1, wherein the functional group known to have click reactivity is selected from the group consisting in thiols, azides, alkynes and alkenes.

3. The method according to claim 2, wherein the functional group known to have click reactivity is a thiol.

4. The method according to claim 2, wherein the functional group known to have click reactivity is an azide.

5. The method according to claim 2, wherein the functional group known to have click reactivity is an alkyne.

6. The method according to claim 2, wherein the functional group known to have click reactivity is an alkene.

7. The method according to claim 1, wherein the natural polymer comprises chitosan.

8. The method according to claim 1, wherein the polymeric textile is a surgical mesh.

9. The method according to claim 1, wherein the polymeric textile is a sling.

10. The method according to claim 1, wherein applying the coating composition includes dipping, wiping, spraying, total immersion, or co-extrusion.

11. The method according to claim 1, wherein the coating composition comprises a solution or suspension.

12. The method according to claim 1, wherein the coating composition comprises a solvent.

13. The method according to claim 1, further comprising adding a bioactive agent possessing a functional group having click reactivity complementary to the functional group having click reactivity of the coating composition, wherein the bioactive agent covalently bonds to the coating composition.

14. The method according to claim 13, wherein the bioactive agent is selected from the group consisting of anti-adhesives, antimicrobials, analgesics, antipyretics, anesthetics, antiepileptics, antihistamines, anti-inflammatories, cardiovascular drugs, diagnostic agents, sympathomimetics, cholinomimetics, antimuscarinics, antispasmodics, muscle relaxants, adrenergic neuron blockers, antineoplastics, immunogenic agents, immunosuppressants, gastrointestinal drugs, diuretics, steroids, lipids, platelet activating drugs, dotting factors, chemotherapeutics and combinations thereof.

15. The method according to claim 1, wherein the polymeric textile comprises a non-absorbable polymer.

16. The method according to claim 1, wherein the polymeric textile comprises an absorbable polymer.

17. The method according to claim 1, wherein the polymeric textile comprises a knit.

18. The method according to claim 1, further comprising knitting a polymeric textile prior to applying the coating composition.
