Systems and methods for treating superficial venous malformations like spider veins

Systems and methods treat superficial venous malformations, such as spider veins. The systems and methods distribute a light-reactive agent, e.g., verteporfin, at or near an inner wall of a vein. The systems and methods activate the light-reactive agent by applying non-thermal light energy at a wave...

Zusammenfassung:Systems and methods treat superficial venous malformations, such as spider veins. The systems and methods distribute a light-reactive agent, e.g., verteporfin, at or near an inner wall of a vein. The systems and methods activate the light-reactive agent by applying non-thermal light energy at a wavelength that activates the light-reactive agent to cause localize injury to the inner wall of the vein.
