Early clinical problems, largely caused by subacute thrombosis (SAT), have been significantly reduced with a new generation of antiplatelet agents. Despite improved pharmacological control of SAT in many patients, the potential for stent occlusion remains a life-threatening problem for those with more complex lesions. One strategy for dealing with this is to improve the hemocompatibility of the stent surface with coatings. A phosphorylcholine (PC)-based stent coating has been designed for this purpose; we describe in detail the evaluation of the device, in vitro, through preclinical and early clinical data. We discuss studies that demonstrate that the PC-coated stent may offer some clinical advantage over uncoated counterparts. The extensive experience with this PC-coated device supports its nonthrombogenic nature, excellent acceptance by arterial tissue, and long-term stability in vivo. These characteristics, together with its ability to load and release a variety of therapeutic agents, also make the device a natural choice of platform for future stent- mediated drug delivery for treating restenosis. %8 2018-04-30
