摘要
In a catheter device and a method for in vivo activation of a photosensitizing drug in a vessel, endovascular tissue, and/or intraluminal tissue, a catheter carrying both an optical coherence tomography (OCT) lens, from which OCT imaging light is emitted, and a photodynamic therapy (PDT) lens from which photosensitizing drug-activating light is emitted, is inserted into a vessel containing a lesion to be treated. A photosensitizing drug is caused to be placed in the vessel as well, such as in the form of a coating on a stent or a coating on an exterior of a balloon carried by the catheter. Light is emitted from the PDT lens to activate the photosensitizing drug while light is simultaneously emitted from the OCT lens to obtain an OCT image to monitor the drug activation.
