Abstract:
A method of ligating a vessel or duct having a maximum cross sectional dimension, the method comprising the steps of:placing adjacent the vessel or duct a pre-clamping device with opposing clamping surfaces movable in relation to one another; positioning such vessel or duct within the opposing clamping surfaces of the pre-clamping device; closing the opposing clamping surfaces of the pre-clamping device around such vessel or duct to effectuate a compression of a portion of the vessel or duct; positioning a ligation clip in an open position around the compressed portion of the vessel or duct using the pre-clamping device, the clip having an opening adapted to receive the vessel or duct, the size of the opening of the clip being less than the maximum cross sectional dimension of the vessel or duct prior to the compression of the duct or vessel; and allowing the ligation clip to close due to its own internal resilience around the compressed portion of the vessel or duct resulting in ligation of the vessel or duct.
