Abstract: The instant invention provides endoluminal methods and devices for the removal of anatomical structures such as vascular structures under endoscopic visualization of the process from within the anatomical structure or surgical 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 which may be passed through the lumen of an elongate vessel or structure, such as for example, the saphenous vein from an entry veinotomy to an exit veinotomy. The guide provides passageways for a variety of surgical devices: an endoscope for viewing the surgical regions of interest, a cautery device and other surgical tools for performing ligation and other surgical procedures, and phleboextractor for removing elongate structures. A porous flexible drain can be deployed to provide pharmacological agents or collecting fluid at the surgical site.
