Abstract

Photodynamic therapy (PDT), the light activation of methylene blue or benzoporphyrin derivatives to produce free-radicals, was shown in vivo to inhibit intimal hyperplasia (IH) and restenosis. The present invention provides an effective clinical approach for PDT treatment which modulates the vascular intervention injury healing response.
