Fig. 4From: Safety and effectiveness of a novel generator algorithm for bipolar vessel sealing: a randomised controlled chronic animal studyHistological comparison between two thermally sealed arteries (BCM top, TSM bottom, left HE stain, right MTC stain): Both samples show similar alterations caused by the sealing process: strong thermal alterations with denaturation of protein components in the vessel wall, of the adventitia and media next to the sealing sites and a transition zone between unaffected and affected mediaBack to article page
