ABSTRACT:
Methods and devices for harvesting blood vessels from the body using minimally invasive surgical techniques are disclosed. The vessel is dissected from surrounding tissue using the tip of a dissection cannula. The dissected tissue may be retracted, for example, by insufflation. The dissection cannula may further include a balloon that can be inflated after insertion between the vessel and the surrounding tissue. An imaging device may be disposed within the cannula to permit viewing through the distal tip. In another aspect, the balloon is an everting balloon that upon inflation everts and advances along the vessel.
