A banding apparatus and method. One embodiment is a unitary or integrated hemorrhoidal single hand-held and single hand-operated ligator, which can, in some embodiments, enable direct visualization and release of multiple bands. The ligator has a gun-shaped handle extending from a vacuum generating trigger tube, with a fixed band bearing barrel extending from the vacuum generating trigger tube. A vacuum generating tube extends through the band bearing barrel from the rear of the gun ligator to the band bearing barrel end of the ligator gun, and is in air movement communication with the vacuum generating tube and band bearing barrel end of the ligator gun. A band actuating barrel is threadably mounted to surround a portion of the band bearing barrel, and rotation of the barrel cause the barrel to move laterally and force one or more ligating bands along and off of the band bearing barrel end. |
