摘要： A method for electrostatic coating of medical devices such as stents and balloons is described. The method includes applying a composition to a polymeric component of a medical device which has little or no conductivity. The polymeric component could be a material from which the body or a strut of the stent is made or could be a polymeric coating pre-applied on the stent. The polymeric component could be the balloon wall. A charge can then be applied to the polymeric component or the polymeric component can be grounded. Charged particles of drugs, polymers, biobeneficial agents, or any combination of these can then be electrostatically deposited on the medical device or the coating on the medical device. One example of the composition is iodine, iodine, iodide, iodate, a complex or salt thereof which can also impart imaging capabilities to the medical device.

摘要： A method for an electrostatic abluminal coating of a stent crimped on a balloon catheter is disclosed. In one form of the method, a stent-balloon assembly is formed by crimping or otherwise mounting a stent on the balloon of a catheter. A conductive wire is thereafter threaded through the lumen of the stent-balloon assembly and a charge is applied thereto. The stent may be grounded or, alternatively, be potentiated with a charge opposite to that of the conductive wire. An electrostatic spray with the same charge as that of the conductive wire may then be applied to the stent-balloon assembly. In this manner, a stent-balloon assembly which is coated on the abluminal surface but substantially or completely free of coating on the luminal surface and the outside surface of the exposed portions of the balloon is realized.
摘要翻译：公开了一种卷曲在球囊导管上的支架的静电空心涂层的方法。在该方法的一种形式中，通过将支架卷曲或以其他方式将导管安装在导管的球囊上来形成支架 - 球囊组件。然后，导线穿过支架 - 气囊组件的内腔，并向其施加电荷。支架可以接地，或者替代地，用与导线相反的电荷进行加强。然后可以将具有与导电线相同电荷的静电喷雾施加到支架 - 气囊组件。以这种方式，实现了涂覆在外腔表面上但基本上或完全没有涂层的支架 - 球囊组件，其在球囊的暴露部分的腔表面和外表面上。
