Claims21
A method of preparing a drug-containing bioabsorbable fiber, the method comprising dissolving both a bioabsorbable polymer and a drug in an organic solvent to form a solution, dispensing the solution into a fiber-shaped mold, evaporating the organic solvent to form a drug-containing bioabsorbable fiber precursor, and drawing the drug-containing bioabsorbable fiber precursor through a die to form the drug-containing bioabsorbable fiber such that the drug-containing bioabsorbable fiber has a uniform diameter, wherein the method is carried out at a temperature of 5° C. to 80° C.
A method of preparing a drug-containing bioabsorbable fiber, the method comprising dissolving both a bioabsorbable polymer and a first drug in an organic solvent to form a solution, dispensing the solution onto a flat surface, evaporating the organic solvent to form a sheet of drug-containing bioabsorbable polymer having at least two edges, joining the at least two edges to form a drug-containing bioabsorbable tube, sealing each end of the drug-containing bioabsorbable tube, and drawing the sealed drug-containing bioabsorbable tube through a die to form the drug-containing bioabsorbable fiber such that the drug-containing bioabsorbable fiber has a uniform diameter, wherein the method is carried out at a temperature of 5° C. to 80° C.
