ligature

 [lig´ah-chur]
any material, such as a thread or wire, used in surgery to tie off blood vessels to prevent bleeding, or to treat abnormalities in other parts of the body by constricting the tissues; see also strangulation. Ligatures are used both inside and outside the body. If one must be left within the body after an operation, the type used will usually be of animal tissue or synthetic material that will dissolve or become incorporated in the patient's own body tissue. Those used on the outside of the body for stitches of cuts or incisions can be of any durable material and are removed after they have served their purpose. Special instruments have been developed for the application of ligatures to parts of the body that are difficult for the surgeon's hands to reach or to work in.
