ABSTRACT:
A blunt dissection cannula and method selectively isolate a vessel of interest within the body of a patient by dissecting connective tissue in and about the adventitial tissue plane. The procedure includes selectively advancing the cannula and transparent tapered tip along the vessel of interior to form an insufflated cavity along the course of the vessel while visualizing the vessel and side branches within the field of view of an endoscope through the transparent tip. An electrocautery electrode selectively extends through an access port at the distal end of the cannula, eccentrically relative to the transparent tip, to facilitate visualizing rotational and translational positioning of the electrode to contact and electrocauterize side branches within the field of view through the transparent tip. A hook-shaped end of the electrode in contact with a cauterized side branch exerts severing tension on the cauterized side branch to isolate the vessel of interest within the insufflated cavity for subsequent transection and removal from the body of the patient.
