US Patent 7628797 System, apparatus, and method for fastening tissue

A clip for securing suture includes a generally tubular body, with one or more tabs cut from the wall of the generally tubular. The tab in an open configuration has the tabs in general alignment with the tab out wall, and the tab in a closed configuration has the tabs bent or otherwise positioned to extend into and at least partially obstruct the inner lumen. The tab may be formed as a generally horse-shoe shaped cut out, and may include a generally elliptical portion having a width and length. The tab may have a width generally the same size as the diameter of the inner lumen. The clip can be formed from memory material such as nitinol, and the clip may be biased toward its closed configuration.
