Abstract
Abstract An improved elastic band for ligating tissue within a living body comprises a central opening defining an axis. A first curved edge is formed between a first surface extending substantially parallel to the axis and a second surface extending substantially perpendicular to the axis. A method of ligating tissue within a living body using such a ligating band comprises the steps of positioning the elastic band, which has been stretched to increase the size of a central opening extending therethrough, adjacent to a portion of tissue to be ligated. The tissue to be ligated is then drawn through the central opening of the elastic band and the elastic band is released so that the size of the central opening decreases to grip the tissue received therein.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
120 words
A method of ligating tissue within a living body comprising the steps of: positioning adjacent to a portion of tissue to be ligated, an elastic band which has been stretched to increase a diameter of a central opening extending therethrough, wherein the central opening defines an axis, and wherein the ligating band comprises a continuous ring, the ring including a first curved edge formed between a first surface extending substantially parallel to the axis and a second surface extending substantially perpendicular to the axis; drawing a portion of tissue to be ligated through the central opening of the elastic band; and releasing the elastic band so that the diameter of the central opening decreases to grip the tissue received therein.
Claim 2
Independent Claim
120 words
A method of ligating tissue within a living body comprising the steps of: positioning adjacent to a portion of tissue to be ligated, an elastic band which has been stretched to increase a diameter of a central opening extending therethrough, wherein the central opening defines an axis, and wherein the ligating band comprises a continuous ring, the ring including a first curved edge formed between a first surface extending substantially parallel to the axis and a second surface extending substantially perpendicular to the axis; drawing a portion of tissue to be ligated through the central opening of the elastic band; and releasing the elastic band so that the diameter of the central opening decreases to grip the tissue received therein.
Claim 3
Dependent Claim
61 words
The method according to claim 1, wherein a curved portion of the cross-section is located at an edge formed between at least one side surface of the elastic band extending substantially perpendicular to the axis and one of an inner longitudinal side thereof extending substantially parallel to the axis and an outer longitudinal side thereof extending substantially parallel to the axis.
Claim 4
Dependent Claim
21 words
The method according to claim 1, wherein a first surface of the elastic band includes a plurality of projections extending therefrom.
Claim 5
Dependent Claim
21 words
The method according to claim 1, wherein a first surface of the elastic band includes a plurality of depressions formed therein.
