<p>A photodynamic composition and a method for in vivo photonic treatments that is minimally invasive, versatile and precise are described. The invention allows for photonic treatments with only minimal insertions into the area of treatment, often a single one. The invention may be used with a standard insertion component making the system inexpensive and easy for doctors to use. The invention has applications in several areas of treatment. In vivo treatment of aesthetic skin blemishes such as varicose veins can be performed with minimal external effects. A predetermined amount of a photodynamic composition, as a foam, is injected into the vein or structure of concern. The composition is a sclerosis foam including a photosensitizer. By external compression, where applicable, the photodynamic composition is forced to remain in the vein or structure. After a predetermined time, radiation of appropriate wavelength from a light source is delivered directly to the vascular structure. Among the key benefits of the present invention are the elimination of targeted varicose veins, without need for anesthesia along the length of the vein; no edema; no skin reaction; and tactile appreciation.</p> |
