Abstract: The method of treating varicose veins and other vascular diseases provides sclerosant fluid through a catheter into the body vessel to be treated. The catheter has a lumen and a plurality of sidewall exits. The sclerosant fluid is provided under sufficient pressure so that it comes out of each exit as a jet of fluid with sufficient velocity to impinge on the vessel wall substantially orthogonal to the wall and thus minimize dilution of the sclerosant fluid and optimize coverage. A movable sheath on the catheter permits selecting a portion of the exits to be uncovered and thus create an infusion zone for the jets of sclerosant fluid which approximately match a desired treatment zone.

Abstract translation: 治疗静脉曲张和其他血管疾病的方法通过导管将硬化流体提供到待治疗的体内容器中。 导管具有内腔和多个侧壁出口。 在足够的压力下提供硬化流体，使得其以每个出口作为流体射流以足够的速度冲击到基本上垂直于壁的容器壁上，从而最小化硬化流体的稀释并优化覆盖。 导管上的可移动护套允许选择出口的一部分未被覆盖，从而为大致匹配期望的治疗区域的硬化流体射流创建输注区域。
