Detection and therapy of vulnerable plaque with photodynamic compounds

The present invention relates to the method for performing alternative target nature photodynamic medical treatment ("PDT") to the inflammatory constituent of a vulnerable plaque. Therefore, the present invention target-izes alternatively the vulnerable check method of a plaque, and the inflammatory constituent of a vulnerable plaque, and offers/or the method of treating a vulnerable plaque by eliminating. Furthermore, the present invention is the intravascular device designed specially, and when excitation light is sent to the surface of the plaque in an artery and a fluorescence signal is detected, it relates to the device which receives the fluorescence which emitted light.
