    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.
