在本文中,我们提供了第一个无聚合物动脉药物洗脱支架的药物洗脱模型。广义模型是能够预测药物从一些无聚合物的系统,包括那些表现出纳米多孔,纳米管和光滑的表面释放。我们推导出的解析解,使我们能够很容易地确定控制药物释放的重要参数。提供药物释放曲线,我们提供设计建议,使释放曲线可以定制,以实现所需的结果。这里介绍的模型并不特定于药物洗脱支架,也可以应用于其他使用纳米多孔表面释放药物的生物医学植入物。
In this paper we provide the first model of drug elution from polymer-free arterial drug-eluting stents. The generalised model is capable of predicting drug release from a number of polymer-free systems including those that exhibit nanoporous, nanotubular and smooth surfaces. We derive analytical solutions which allow us to easily determine the important parameters that control drug release. Drug release profiles are provided, and we offer design recommendations so that the release profile may be tailored to achieve the desired outcome. The models presented here are not specific to drug-eluting stents and may also be applied to other biomedical implants that use nanoporous surfaces to release a drug.
