Methods and devices for harvesting blood vessels using balloons to dissect and mobilize the blood vessel from surrounding tissue are disclosed. A tunnel is created over the blood vessel. The tunnel is insufflated. A balloon dissector is inflated over the blood vessel. Side branches are then ligated and divided from the blood vessel. In a further aspect of the invention, the balloon may be an everting balloon which, upon inflation, advances along the blood vessel and envelops the blood vessel.
