Abstract

See full text

Methods and systems for manufacturing an implantable medical device, such as a stent, from a tube with desirable mechanical properties, such as improved circumferential strength and rigidity, are described herein. Improved circumferential strength and rigidity may be obtained by inducing molecular orientation in materials for use in manufacturing an implantable medical device. Some embodiments may include inducing molecular orientation by expansion of a molten annular polymer film. Other embodiments may include inducing circumferential molecular orientation by inducing circumferential flow in a molten polymer. In certain embodiments, circumferential orientation may be induced by expansion of a polymer tube. Further embodiments may include manufacturing an implantable medical device from a biaxially oriented planar polymer film.
