A membrane (40) is provided for implantation in a coronary artery (20) of a patient. The membrane preferably includes a substantially-cylindrical elastometric polyurethane body, adapted for subsequent application to a coronary artery stent (30). The body of the membrane typically includes one or more pharmaceutical products, e.g., an anti-inflammatory agent and an anti-proliferative agent, optionally disposed on different respective layers (34, 36) of the membrane. |
