    • According to an aspect of the invention, medical devices are provided, which have the following (a) one or more superhydrophobic surface regions, (b) one or more superhydrophilic surface regions having a durometer of at least 4OA, or (c) a combination of one or more superhydrophobic surface regions and one or more superhydrophilic surface regions having a durometer of at least 4OA. Such surfaces are created, for example, to provide reduced resistance to the movement of adjacent materials, including adjacent fluids and solids. Examples of medical device surface regions benefiting from the present invention include, for example, outside and/or inside (luminal) surfaces of the following: vascular catheters, urinary catheters, hydrolyser catheters, guide wires, pullback sheaths, left ventricular assist devices, endoscopes, airway tubes and injection needles, among many other devices.
    • 根据本发明的一个方面,提供了医疗装置,其具有以下(a)一个或多个超疏水表面区域,(b)一个或多个具有至少40A的硬度的超亲水性表面区域,或(c)组合 的一个或多个超疏水表面区域和一个或多个具有至少40A的硬度的超亲水表面区域。 例如,这样的表面被创建以提供对相邻材料,包括相邻流体和固体的运动的降低的阻力。 受益于本发明的医疗器械表面区域的实例包括例如以下的外部和/或内部(腔)表面:血管导管,导尿管,水解导管,引导线,回拉鞘,左心室辅助装置,内窥镜 ,气道管和注射针等。
