An apparatus for the treatment ol venous stasis includes an elongated intraluminal member shaped and dimensioned for passage through vessels of a subject. The intraluminal member includes a proximal end and a distal end. A conduit extends from proximate the proximal end of the intraluminal member to proximate the distal end of the intraluminal member. The conduit is shaped and dimensioned for fluid communication between the proximal end of the intraluminal member and the distal end of the intraluminal member. The distal end of the intraluminal member includes disruption means proximate thereto for ablating a predetermined vessel wall. A method is also provided for the treatment of venous stasis. The method is achieved by advancing an elongated intraluminal member through a vein to a treatment site, activating the intraluminal member for ablation of the treatment site and injecting sclerosant into the vein at the treatment site.
