The instant invention provides endo-luminal methods, and devices for the removal of anatomical structures such as vascular structures under endoscopi c visualization of the process from within the anatomical structure or surgica l region of interest. The present invention allows a surgeon to perform these procedures using a small number of small incisions. The present invention provides an elongated flexible endoscopic guide (12) which may be passed through the lumen of an elongate vessel or structure, such as for example, t he saphenous vein from an entry venotomy to an exit venotomy. The guide (12) provides passageways for a variety of surgical devices, an endoscope (24) fo r viewing the surgical regions of interest, a cautery device (26) and other surgical tools for performing ligation, and other surgical procedures, and phlebo-extractor (30) for removing elongate structures. A porous flexible drain can be deployed to provide pharmacological agents or collecting fluid at the surgical site. In the preferred embodiment, the device is used to care f or chronic venous insufficiency, varicose saphenous vein segments, venous insufficiency, and varicose veins, by removal of those veins or segments.</S DOAB>
