Drug-eluting intravascular prostheses and methods of use
The present invention provides intravascular prostheses and methods of production and use. An implantable device for treating a vascular disease or disorder includes an intravascular prosthesis containing an inhibitor of smooth muscle cell proliferation and a growth factor. The device can be coated with a biodegradable drug-eluting polymer that is impregnated with the inhibitor of smooth muscle cell proliferation and the growth factor. The device is useful for treating or preventing a vascular disease or disorder such as restenosis, by simultaneously inhibiting vessel blockage and enhancing recovery of the vessel wall following an intravascular intervention.
1. An implantable device for treating a vascular disease or disorder comprising an intravascular prosthesis, wherein said device is coated with a biodegradable drug-eluting polymer that is impregnated with an inhibitor of smooth muscle cell proliferation and a growth factor for enhancing endothelial cell proliferation, wherein said inhibitor of smooth muscle cell proliferation is fibulin-5 polypeptide or a nucleic acid encoding fibulin-5 polypeptide, and wherein said growth factor for enhancing endothelial cell proliferation is VEGF polypeptide or a nucleic acid encoding VEGF polypeptide.
2. The device of claim 1 , wherein the intravascular prosthesis is a stent.
3. The device of claim 1 , wherein the vascular disease is restenosis.
4. The device of claim 1 , wherein said fibulin-5 and said VEGF are released slowly by degradation of said polymer.
5. An implantable device for treating a vascular disease or disorder comprising an intravascular prosthesis, wherein said device is coated with a substrate comprising endothelial cells that are genetically altered to express or over-express an inhibitor of smooth muscle cell proliferation and a growth factor for enhancing endothelial cell proliferation, wherein said inhibitor of smooth muscle cell proliferation is fibulin-5 polypeptide, and wherein said growth factor for enhancing endothelial cell proliferation is VEGF polypeptide.
6. The device of claim 5 , wherein said intravascular prosthesis is a stent.
7. The device of claim 5 , wherein said vascular disease is restenosis.
