Vessel harvesting tools consist of first and second vessel engaging members configured and adapted to engage the vessel. The first engaging member and the second engaging member are axially and rotatably adjustable with respect to one another. The main use of these tools is to place the elongate body structure between the first and the second vessel engaging members and axially manipulating the first engaging member with respect to the second engaging member to separate the elongate body structure from surrounding tissue.
