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.

Abstract: Devices and methods for treatment of prolapsed hemorrhoidal arteries is disclosed. The devices can identify the hemorrhoid and ligate the artery without causing significant pain or distension of the rectum. The artery can be identified with ultrasound. The ligation can be performed using energy and/or mechanical structures, such as clips or rubber bands.

Abstract: A device and method for treatment of hemorrhoids, in which the devices includes: a housing insertable into the rectum; a tissue port configured to receive a tissue segment containing at least a portion of a hemorrhoidal blood vessel; opposing needle chambers including at least one pair of corresponding needles coupled by a suture in which the pair of corresponding needles are substantially opposite to one another and in an active position substantially aligned with the tissue segment; a needle driver that advances the pair of corresponding needles through the tissue segment to encircle a portion of the hemorrhoidal blood vessel with the suture, thereby ligating the hemorrhoidal blood vessel; and an actuator coupled to at least one of the needle chambers that actuates the needle chambers such that another pair of corresponding needles is in the active position.
