<p>The present invention relates to devices and methods for removing veins in a venous system of a patient. One device for removing undesired veins includes an elongated member (102) having first and second lumens (188, 120) extending longitudinally therein. The first lumen (118) extends from the proximal end of the elongated member (102) to a first opening (122) at the distal end of the member. The second lumen (120) extends from the proximal end of the elongated member (102) to a second opening (124) in the side of the elongated member (102). The proximal end of the elongated body is coupled to a connector having two separate tubes that communicate with the respective first and second lumen for the injection and removal of fluid. A vein attachment member (110), attached to the elongated member (102), is adapted to be secured to the vein. One method of removing undesired veins includes the steps of inserting a surgical instrument to a desired point along the vein, and attaching the distal end of the vein to the surgical instrument. The method also includes the steps extracting the surgical instrument to cause the vein to separate from its surrounding tissue, and supplying fluid through the instrument into the tissue where the vein has been extracted.</p> |
