Abstract: A scaffold strut is shaped to improve hemocompatibility. The scaffold is made from a tube having variable wall thickness. Methods are disclosed for modifying the thickness of the tube in such a way as to achieve a reduced hemodynamic profile, but without significantly affecting strength properties in areas where stress concentrations exist when the scaffold is loaded.

Abstract: An endoprosthesis, a method for imaging an endoprosthesis, a method of making an endoprosthesis involve a polymeric substrate that has been modified to have voids embedded within the substrate. The voids are sized to scatter optical radiation from within the substrate so that an optical coherence tomography (OCT) image can be obtained in which an interior region of the substrate can be easily differentiated from empty space and other structures that surround the endoprosthesis. The voids allow for OCT visualization of the polymeric substrate which may be difficult to visualize by other methods such as fluoroscopy.

Abstract: Methods of treating coronary artery disease (CAD) with bioresorbable stents resulting in reduced angina or non-ischemic chest pain are described. Methods of treatment and devices for treatment of angina and post-procedural chest pain that include anti-angina agents incorporated into the device are disclosed.
