Abstract:
A method including forming a semi-crystalline polymer material into a lamella; and stretching the lamella into a polymer including a node of folded lamella and a fibril orientation. A method including extruding a pseudo-gel including an ultrahigh molecular weight polyethylene material into a lamella; stretching the lamella into a polymer including a node of folded lamella and a fibril orientation; and annealing the polymer at a temperature sufficient to define the node and fibril orientation. An apparatus including a body portion formed of a dimension suitable for a medical device application and including a semi-crystalline polymer arrayed in a node of folded lamella and a fibril orientation. An apparatus including a body portion including an ultra-high molecular polyethylene material arrayed in a node of folded lamella and a fibril orientation.
