example

[0075] The superficial venous anatomy of the ears of New Zealand White Rabbits were treated by injecting light-reactive agent LS11 (Talaporfin Sodium) in doses selected to approximate a human dose, and thereafter exposing the superficial venous anatomy to light at a wavelength of 664 nm in dose periods ranging from 8 to 12 minutes. Visible alterations in the superficial venous anatomy due to shrinkage of veins in the treated regions were observed.

[0076] New Zealand Rabbits were chosen because of their large ears having easily identifiable superficial venous anatomy (as FIG. 19 shows). A total of twelve rabbits were treated. Each rabbit (weighing approximately six pounds) was intravaneously sedated for approximately 25 minutes using Ketamine and secured to a treatment table before being treated. The ears were shaved clean of hair and skin prepped with alcohol.

[0077] LS11 (Talaporfin Sodium, from Light Sciences Oncology, Inc.) was selected as the light reactive agent 14. As FIG. 19 ...

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.

Description

RELATED APPLICATION [0001] This application is a continuation-in-part of co-pending U.S. patent application Ser. No. 11 / 446,800, filed Jun. 5, 2006 and entitled “Systems and Methods for Treating Superficial Venous Malformations Like Spider Veins,” which claims the benefit of U.S. Provisional Patent Application Ser. No. 60 / 796,656, filed May 2, 2006, and entitled “Systems and Methods for Treating Superficial Venous Malformations Like Spider Veins,” which are both incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] As the large group of so-called baby-boomers advances in age, there are increasing demands for effective, non-invasive treatment of vascular diseases or dysfunctions affecting the vascular system. There are also increasing demands for non-invasive cosmetic surgery to repair conditions that have vascular origins. [0003] For example, spider veins result from various dysfunctions in the veins. Veins carry oxygen-poor blood from the body back to the heart. [0004...
