Unitary surgical devices are disclosed. Such devices may include an elongated body extending between a proximal end and a distal end, and having one or more lumens extending through the elongated body and a tip disposed at the distal end of the elongated body. The harvesting device may further include a first gripping element disposed about the dissection tip and a second gripping element disposed about the dissection tip distally of the first gripping member. The second gripping member may be moveable with respect to the first gripping member for capturing a blood vessel between the first gripping member and the second gripping member. The blood vessel captured between first gripping member and the second gripping member may then be sealed and, subsequently, severed by a cauterizing element disposed between the first gripping member and the second gripping member.
