A method of harvesting a blood vessel, comprising:
- advancing a conical dissection tip of an endoscopic cannula along an exterior surface of the blood vessel to separate the blood vessel from surrounding tissue, wherein a branch vessel that emanates from the blood vessel is encountered during said advancing;
- viewing the branch vessel through a transparent portion of the conical dissection tip via an endoscope received in the endoscopic cannula, wherein the transparent portion of the conical dissection tip includes at least a first visual cue that is visible to a user looking through the transparent portion with the endoscope to allow the user to confirm positioning of the conical dissection tip during said viewing;
- energizing a cutting element positioned adjacent the branch vessel to seal off part of the branch vessel;
- and
- mechanically cutting through a sealed-off portion of the branch vessel with the cutting element.
