Abstract
Apparatus and methods are provided for localized, minimally invasive administration of sclerotherapy in the treatment of varicose veins. A treatment site within a vein is isolated from blood flow through the vain. Sclerotherapeutic agents are delivered to the isolated vessel segment. A substantial portion of the agents are then removed from the vein, and isolation is removed from the treatment site. Inflammation, clotting, scarring, and closure of the varicose vein ensues at the treatment site. In a preferred embodiment, this technique is accomplished with a catheter having an inflatable member. The inflatable member is expandable to a deployed configuration in which its central region is of reduced cross-section as compared to its proximal and distal regions. The central region comprises one or more perforations extending through the inflatable member so that sclerotherapeutic agents may be delivered through the perforations.
