Fluid treatment of a polymeric coating on an implantable medical device
First Claim
Patent Images
1. A method of manufacturing a drug delivery implantable medical device, comprising:
- applying a composition to an implantable medical device, the composition including a polymer, an active agent and a solvent;
allowing the solvent to evaporate to form a dry coating, the dry coating comprising less than about 2% residual fluid content (w/w);
applying a fluid to the dry coating, the fluid being substantially or completely free from any polymer; and
removing the fluid from the coating.

26. A method of manufacturing a stent coating, comprising:
-
applying a composition to a stent, the composition including a semicrystalline polymer and a solvent; allowing the solvent to evaporate to form a dry coating, the dry coating comprising less than about 2% residual fluid content (w/w); and exposing the coating to a fluid for a sufficient duration to increase the crystallinity of the polymer in at least a portion of the coating, the fluid being substantially or completely free from any polymer; and removing the fluid from the coating. - View Dependent Claims (27, 28, 29, 30, 31, 33, 34, 40, 41, 42, 45, 46)
