    • The present invention relates to a method of polishing an implantable medical device. The method may include positioning an implantable medical device on a support. At least a portion of a surface of the implantable medical device may include a polymer. A fluid may be contacted with at least a portion of the surface of the positioned implantable medical device. In an embodiment, the fluid may be capable of dissolving at least a portion of the polymer at or near the surface of the implantable medical device. The method may further include allowing the fluid to modify at least a portion of the surface of the positioned medical device. A majority of the contacted fluid may be removed from the surface of the implantable medical device. In certain embodiments, the modified portion of the surface may be substantially less thrombogenetic and substantially more mechanically stable than an unmodified surface.
    • 本发明涉及一种抛光可植入医疗器械的方法。 该方法可以包括将可植入医疗装置定位在支撑件上。 可植入医疗装置的表面的至少一部分可以包括聚合物。 流体可以与定位的可植入医疗装置的表面的至少一部分接触。 在一个实施方案中,流体可能能够将聚合物的至少一部分溶解在可植入医疗装置的表面处或附近。 该方法还可以包括允许流体修改定位的医疗装置的表面的至少一部分。 接触流体的大部分可以从可植入医疗装置的表面移除。 在某些实施方案中,表面的改性部分可以比未修饰的表面基本上更少的血栓形成和基本上更机械稳定的。
