CPC classification number: A61L27/56 , A61F2/0077 , A61L27/16 , D04H1/54 , D04H5/00 , Y10T428/24355 , Y10T428/24372 , Y10T428/24496 , Y10T428/2457 , Y10T428/24579 , Y10T428/249964 , Y10T428/249978 , Y10T428/8305 , C08L27/18
Abstract: Improved processes for surface treating expanded polytetrafluoroethylene (PTFE) is disclosed and improved surface-treated devices made from the processes. The processes employ a laser to surface-modify an expanded PTFE structure to create a macro-roughened surface that has the capability to remain microporous throughout. The unique process of the present invention creates a ridge and valley structure on the surfaces of devices that includes unique gnarled nodes along valley floors.
Abstract translation: 公开了用于表面处理膨胀聚四氟乙烯（PTFE）的改进方法，并且改进了由该方法制成的表面处理装置。 该方法采用激光来表面改性膨胀的PTFE结构以产生具有保持微孔的能力的宏观粗糙化表面。 本发明的独特过程在装置的表面上形成了一个脊和谷结构，其中包括沿着谷底的独特的节点。
