Abstract
Controlled release vascular implants, such as vascular grafts, stents, wraps, and gels comprising a biocompatible polymer and all trans retinoic acid (ATRA), or its derivatives, can be used to treat, prevent, or inhibit thrombosis and/or neointimal hyperplasia which may otherwise be induced by prosthetic implantation. In particular, the implants herein can inhibit smooth muscle cell proliferation, neointimal hyperplasia, and upregulate antithrombotic genes and nitric oxide production in the vasculature. Further, the implants are capable of delivering controlled and predictable localized concentrations of ATRA.
