Abstract
An improved endoscopic ligature provided with a loop support means for stabilizing the shape, position and orientation of a suture loop. The stabilized loop is impervious to surface tension forces created by body fluids and will not close on itself or stick to moist surfaces. When the loop is cinched closed it dislodges from the support. The loop support is made of a flexible material with shape memory and has an unstressed width greater than that of the trocar cannula. The loop support is collapsible to allow the instrument to be inserted and withdrawn through the cannula.
