Systems and methods for treating superficial venous malformations like spider veins
First Claim
Patent Images
1. A method for treating a spider vein comprising providing a reactive agent that is controllably activated by the application of a prescribed form of energy, distributing the reactive agent at, in, or near an inner wall of a spider vein, and activating the reactive agent by applying the prescribed form of energy that activates the reactive agent in situ to cause localized injury to the inner wall of the spider vein.

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

47. A method for treating superficial venous malformations comprising
providing a light-reactive agent, distributing the light-reactive agent at, in, or near an inner wall of a vein, and activating the light-reactive agent by applying light energy from a light emitting diode having a wavelength that activates the light-reactive agent to cause localized injury to the inner wall of the vein.
-
49. A system comprising
a light-reactive agent, is a photoactivation device comprising at least one light-emitting diode operating to emit light at a wavelength that activates the light-reactive agent, and directions for using the light-reactive agent and the photoactivation device to treat a superficial venous malformation.
