    Abstract: The medical devices of the invention have a portion with a porous surface for release of at least one biologically active agent therefrom. The porous surface is made of a material such as a polymer having a plurality of voids. To load the porous surface with a biologically active agent or drug, an electrophoresis method is employed. In this method, a device having a porous surface is placed into a drug solution or suspension, along with an electrode. An electric current is applied to the device and electrode. Under such a current, the drug, which has a positive or negative charge, will be loaded into the pores or voids of the porous surface.

    Abstract translation: 本发明的医疗装置具有用于从其释放至少一种生物活性剂的多孔表面的部分。 多孔表面由诸如具有多个空隙的聚合物的材料制成。 为了用生物活性剂或药物加载多孔表面,使用电泳方法。 在该方法中,具有多孔表面的装置与电极一起放入药液或悬浮液中。 电流被施加到器件和电极上。 在这样的电流下,具有正电荷或负电荷的药物将被加载到多孔表面的孔或空隙中。
