Devices for harvesting veins or other elongate structures from the body are disclosed. The disclosed devices allow vein harvesting using endoscopic procedures. A working space is created over a vein (6) using standard endoscopic procedures and a side-hooked wire (39) is inserted into the working space and twisted to insert the side-hook (42) under the vein (6). The wire (39) is then pulled or drawn along the vein (6) to separate the vein (6) from the surrounding tissue.
