Abstract

A method of ligating anatomical tissue using a suture spring device of coiled configuration includes expanding the suture spring device from a relaxed, unexpanded state to an elastically deformed, expanded state, positioning the anatomical tissue in an axial space between rings or coils of the suture spring device when the device is in the elastically deformed, expanded state, and allowing the suture spring device to contract from the expanded state toward the unexpanded state to ligate the anatomical tissue. The rings or coils of the suture spring device can be axially and/or radially expanded in the elastically deformed, expanded state. In the case of the rings being radially expanded, the anatomical tissue is preferably repositioned to be disposed concentrically within a central longitudinal passage or aperture of the suture spring device so that the rings are coiled around the anatomical tissue in the expanded state and able to apply a radially compressive force when contracted. In the case of the rings being axially expanded, the anatomical tissue is maintained in the axial space between rings when the suture spring device is in the expanded state so that, when the device is allowed to contract, an axially compressive force is applied which will ligate the anatomical tissue.
