Medical devices having activated surfaces
Implantable biocompatible polymeric medical devices include a substrate with an acid or base-modified surface which is subsequently modified to include click reactive members.
1. A polymeric medical device having an acid or base-treated surface that is functionalized with one or more click reactive members to provide an activated surface on the polymeric medical device.
2. The medical device of claim 1 , wherein the medical device comprises a biodegradable polymer selected from collagen, cellulose, poly (amino acids), polysaccharides, hyaluronic acid, copolymers and combinations thereof.
3. The medical device of claim 1 , wherein the medical device comprises a non-degradable polymer selected from fluorinated polymers, polyolefins, nylons, polyamides, polyurethanes, silicones, ultra high molecular weight polyethylene, polybutesters, polyaryletherketone, copolymers and combinations thereof.
4. The medical device of claim 1 , wherein the one or more click reactive members are selected from the group consisting of thiols, azides, alkynes and alkenes.
5. The medical device of claim 1 , wherein the one or more click reactive members comprise a thiol.
6. The medical device of claim 1 , wherein the one or more click reactive members comprise an azide.
7. The medical device of claim 1 , wherein the one or more click reactive members comprise an alkyne.
8. The medical device of claim 1 , wherein the one or more click reactive members comprise an alkene.
9. The medical device of claim 1 , wherein the medical device is selected from the group consisting of monofilament sutures, multifilament sutures, surgical meshes, ligatures, staples, slings, patches, foams, pellicles, films, barriers, stents, catheters, and inflatable balloons.
10. The medical device of claim 1 , wherein the medical device comprises a surgical mesh.
11. The medical device of claim 1 , wherein acid or base-treated surface is hydrolyzed prior to being functionalized with the at least one click-reactive member.
12. The medical device of claim 1 , wherein the acid treated surface is treated with an acid selected from the group consisting of HCl, HCl 3 , HCl 4 , H 2 SO 3 , H 2 SO 4 , H 3 PO 4 , HI, HIO 3 , HBr, lactic acid and glycolic acid.
13. The medical device of claim 1 , wherein the base treated surface is treated with a base selected from the group consisting of LiOH, Ba(OH) 2 , Mg(OH) 2 , NaOH, KOH, Na 2 CO 3 , Ca(OH) 2 , and NH 4 OH.
14. The medical device of claim 1 , further comprising a drug functionalized with one or more complementary click reactive members, wherein the one or more click reactive members of the medical device and the one or more complementary click reactive members of the drug interact to covalently bond the drug to the activated surface of the medical device.
15. The medical device of claim 14 , wherein the one or more click reactive members comprise a thiol and the one or more complementary click reactive members comprise an alkene.
16. The medical device of claim 14 , wherein the one or more click reactive members comprise an alkene and the one or more complementary click reactive members comprise a thiol.
17. The medical device of claim 14 , wherein the one or more click reactive members comprise an alkyne and the one or more complementary click reactive members comprise an azide.
18. The medical device of claim 14 , wherein the one or more click reactive members comprise an azide and the one or more complementary click reactive members comprise an alkyne.
