Abstract
Abstract A hemorrhoid ligature element including an elongated cylindrical elastic body having a central bore. The outside of the body and the inner surface of the bore may have circumferential grooves for gripping tissue. The length of the element is substantially longer than the radius making the element roll-resistant.

A hemorrhoid ligature element comprising: an elongated, cylindrical elastic body having a central bore extending therethrough; the length of said body being substantially longer than a radius of said body measured from a periphery of said bore to an outer peripheral surface of said body, whereby said ligature element is roll-resistant; said outer peripheral surface including at least one circumferential groove for making the outer peripheral surface slide-resistant; said central bore including at least one circumferential groove extending radially into the body for receiving tissue therein, thereby increasing a coefficient of friction between the ligature element and the tissue.
