Abstract:
The present invention provides an expanded tubular graft formed of expanded polytetrafluoroethylene (ePTFE). The graft has first and second open ends and a surface longitudinally extending between the ends. The graft also includes an inner and outer cylindrical walls, where the walls have crimps or corrugations located along the surface of the graft. Additionally, the graft is coated with biocompatible elastomer covering portions of the outer cylindrical walls of the PTFE graft. The resulting ePTFE crimped graft exhibits various enhanced properties, such as adjustable graft length, high kink resistance, improved suture retention and high crush resistance as compared to the same graft without the crimps.
