Title: Skewed nodal-fibril ePTFE structure

Abstract: The ePTFE structure includes an ePTFE tubular structure having opposite ends and a longitudinal axis. The ePTFE tubular structure is formed from rotating the opposite ends relative to one another in a direction of rotation about the longitudinal axis. The ePTFE tubular structure has a node and fibril micro-structure in which substantially all of the fibrils are oriented in the direction of rotation.
