Claim:
1. A hand-holdable ligator apparatus configured to ligate tissue, the apparatus comprising: a rigid elongate body having a proximal end and a distal end, the distal end configured to hold a ligating band thereon; a rigid vacuum draw tube extending within the rigid elongate body from the proximal end to the distal end along a straight first axis; a rigid viewing tube separate from the vacuum draw section and extending within the rigid elongate body from the proximal end to the distal end along a straight second axis that is parallel with the first axis, the rigid viewing tube having a translucent or transparent distal section configured to allow visualization of the tissue from the proximal end of the rigid elongate body; a ligating band actuator slidably mounted about the elongate body and configured to release the ligating band from the distal end of the rigid elongate body; a hand-holdable handle attached to the elongate body; and a vacuum actuator trigger attached to the hand-holdable handle, the trigger including a spring configured to compress to remove air from the vacuum section and to release to provide suction through the vacuum draw section to suction the tissue to the distal end of the rigid elongate body.
