  • Surface modified expanded polytetrafluoroethylene devices and methods of producing the same
    Patent number: 7736576
    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.
    Type: Grant
