1. A method of preparing a coated medical device, the method comprising:
- combining fish oil with vitamin E and one or more therapeutic agents to form a combined fish oil-vitamin E-therapeutic agents material, wherein the fish oil comprises two or more omega-3 fatty acids;
applying the combined fish oil-vitamin E-therapeutic agents material to a medical device; and
heat curing the combined fish oil-vitamin E-therapeutic agents material to cross-link the two or more omega-3 fatty acids directly to each other by one or more of ester bonds and lactone bonds, thereby forming the coated medical device.

10. A method of preparing a bioabsorbable coating or film, the method comprising:
-
partially heat curing fish oil to cross-link two or more fatty acids contained therein directly to each other by ester bonds to form a partially cured fish oil; combining the partially cured fish oil with a therapeutic agent to form a combined fish oil-therapeutic agent material; and heat curing the combined fish oil-therapeutic agent material to cross-link the two or more fatty acids directly to each other by ester bonds, thereby forming the bioabsorbable coating or film. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A method of preparing a coated medical device, the method comprising:
-
partially curing fish oil to cross-link two or more fatty acids contained therein directly to each other by one or more of ester bonds and lactone bonds so as to form a partially cured fish oil; combining the partially cured fish oil with a therapeutic agent to form a combined partially cured fish oil-therapeutic agent material; applying the combined partially cured fish oil-therapeutic agent material to a medical device; and heat curing the combined partially cured fish oil-therapeutic agent material to further cross-link two or more of the fatty acids directly to each other by one or more of ester bonds and lactone bonds, and thereby forming the coated medical device. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
