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: A medical device system is provided herein which has an elongated, flexible hollow member with an expandable infusion segment attached at the most distal end of the device. The device has a plurality of fluid infusion ports on the expandable infusion segment for delivering an intended fluid to a target site in a body lumen. Additionally, a method is provided herein for infusing an intended fluid to a target site within a body lumen.

Abstract: A multilumen catheter assembly and method of making the catheter assembly is provided that involves providing a plurality of tubes, each tube having a first end, a second end, at least one lumen, and at least one surface, selectively heating at least a portion of the surface of at least a first tube of the plurality of tubes, and contacting the selectively heated portion of the tube with a portion of the surface of a second tube to form a multilumen catheter shaft that is joined together along at least a portion of the length of the catheter shaft.

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。
