1. A method for harvesting a blood vessel comprising:
advancing, towards the blood vessel, an elongated body defining a central axis and having a conical tip disposed at its distal end to facilitate movement through tissue;
moving an end effector from a position proximal to the conical tip distally to a position distal to a proximal end of the conical tip and moving the end effector along a circumferential path about the conical tip and the central axis to capture the blood vessel; and
operating a control to energize the end effector to perform at least one of sealing the blood vessel, cutting the blood vessel, or a combination thereof.
