Claims18
A method for coating an implantable medical device, comprising:
- (a) dissolving a poly(ethylene-co-vinyl alcohol) and a drug in a solvent system comprising a first solvent and a co-solvent to form a solution, wherein the co-solvent is an organic solvent having the dielectric constant less than about 10 at room temperature;
- and
- (b) applying the solution onto the medical device to form the coating.
A method for coating an implantable medical device, comprising:
- (a) dissolving a poly(ethylene-co-vinyl alcohol) and a drug in a solvent system comprising a first solvent and a co-solvent to form a solution, wherein the co-solvent is an organic solvent having surface energy less than about 30 dyne/cm at room temperature;
- and
- (b) applying the solution onto the medical device to form the coating.
A method for coating an implantable medical device, comprising:
- (a) dissolving a poly(ethylene-co-vinyl alcohol) and a drug in a solvent system comprising a first solvent and a co-solvent to form a solution, wherein the co-solvent is an organic solvent having a viscosity not exceeding about 1 centipoise at room temperature;
- and
- (b) applying the solution onto the medical device to form the coating.
