11541152 · 2023-01-03 ·

Medical devices such as stents, stent grafts, and balloon catheters include a coating layer applied over a modified exterior surface of the medical device. The modified exterior surface comprises an exterior surface of the medical device subjected to a surface modification that decreases a surface free energy of the exterior surface before application of the coating layer an exterior surface. The coating layer comprises a hydrophobic therapeutic agent and at least one additive. The modified exterior surface may affect the release kinetics of the drug from the device, the crystallinity of the drug layer, the surface morphology of the coating and particle shape, or the particle size of drug of a therapeutic layer in the coating layer. For example, the effects caused by the modified exterior surface may increase the retention time and amount of therapeutic agent in tissue.
