Abstract
Apparatus and methods are provided for ligating a hemorrhoidal blood vessel for treatment of hemorrhoids. An exemplary apparatus includes a housing having a distal end insertable into the rectum, an ultrasound sensor, suction channel, and suction port on the distal end; and a compression clip, proximate to the suction port and having two clip arms displaceable from each other, the compression clip having an open configuration within the housing yet biased towards a closed configuration, and wherein the compression clip is deployable in the open configuration and configured to close and compress a tissue segment.

An apparatus for ligating hemorrhoidal arteries for treatment of hemorrhoids comprising:
- a housing extending along a longitudinal axis and having a distal end insertable into a rectum of a subject;
- a suction chamber carried on the housing and defining an open cavity for creating a tissue fold through suction, the suction chamber configured to receive one or more clips deployable to compress and ligate a hemorrhoidal artery;
- an ultrasound sensor proximal to the suction chamber and configured to locate a hemorrhoidal artery;
- a first control configured to be operable by a user outside the rectum of the subject to activate suction in the suction chamber;
- and
- a second control configured to be operable by the user outside the rectum of the subject to deploy the one or more clips to compress and ligate the hemorrhoidal artery.
