Abstract
A coated medical device and a method of providing a coating on an implantable medical device result in a medical device having a bio-absorbable coating. The coating includes a bio-absorbable carrier component. In addition to the bio-absorbable carrier component, a therapeutic agent component can also be provided. The coated medical device is implantable in a patient to effect controlled delivery of the coating, including the therapeutic agent, to the patient.

36. A coated medical device, comprising:
-
a pre-treatment provided on the medical device having a first bio-absorbable cross-linked material; and a coating disposed on top of the pre-treatment, the coating having a second bio-absorbable cross-linked material, a cellular uptake inhibitor, a therapeutic agent; wherein the pre-treatment improves consistency and conformability and enhances the adhesion of the coating to the medical device; wherein the coated medical device is implantable in a patient to effect controlled delivery of the therapeutic agent to the patient; wherein the controlled delivery is at least partially characterized by total and relative amounts of the cellular uptake inhibitor and bio-absorbable cross-linked material; and wherein the bio-absorbable cross-linked material comprises two or more omega-3 fatty acids cross-linked into a substantially random configuration by ester bonds. - View Dependent Claims (37, 38, 39)
