Abstract
A method for coating an implantable medical device that has the steps of applying a polymer composition onto the device, the polymer composition including a solution of a polymer in a solvent, and drying the polymer composition for a period of time at a drying temperature higher than the room temperature in an environment having relative humidity between about 20% and about 100%.
Claims17
A method for coating an implantable medical device, comprising:
- (a) applying a polymer composition onto the device, the polymer composition including a solution of a polymer in a solvent wherein the solvent comprises a solvent having a boiling point greater than about 120° C. at atmospheric pressure and/or wherein the solvent comprises a solvent having a vapor pressure less than about 15 Torr at 20° C.;
- and
- (b) drying the polymer composition for a period of time at a drying temperature between 30° C. and 110° C. in an environment having relative humidity between about 20% and about 100%.
A method for coating an implantable medical device, comprising:
- (a) applying a coating material including a polymer and a solvent to the device wherein the solvent comprises a solvent having a boiling point greater than about 120° C. at atmospheric pressure and/or wherein the solvent comprises a solvent having a vapor pressure less than about 15 Torr at 20° C.;
- and
- (b) drying the coating material in an oven for a period of time at a drying temperature between 30° C. and 110° C., wherein the oven has a relative humidity between about 20% and about 100%.
