    摘要: 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.

    摘要: Provided herein is a method of forming medical device that includes RGD attached to the device via a spacer compound. The method comprises providing a spacer compound comprising a hydrophobic moiety and a hydrophilic moiety, grafting or embedding the spacer compound to the surface layer of the polymer to cause the hydrophobic moiety to be grafted to or embedded within the surface layer of polymer, and attaching a chemo-attractant to the hydrophilic moiety.
