    • The present invention is directed to medical implants that are configured to controllably release therapeutic agent to a target site of a patient and methods of making these implants. Embodiments of the present invention may include a method comprising the steps of providing a tube having a wall with inner and outer surfaces and defining a passageway, forming an opening through the wall of the tube, applying a porous coating layer to at least one of the inner and outer surfaces of the tube, and loading a therapeutic agent solution into the passageway so that therapeutic agent passes through the opening and into the porous coating layer. The method may also include removing portions of the tube to form the implantable medical device, which may be a stent.
    • 本发明涉及被配置为将治疗剂可控地释放到患者的靶位点的医疗植入物和制造这些植入物的方法。 本发明的实施例可以包括一种方法,包括以下步骤:提供具有内壁和外表面的壁的管,并限定通道,形成穿过管壁的开口,将多孔涂层施加到至少一个 管的内表面和外表面,并将治疗剂溶液装载到通道中,使得治疗剂通过开口并进入多孔涂层。 该方法还可以包括去除管的部分以形成可植入的医疗装置,其可以是支架。
