Abstract
A surgical device for ligating and severing a vessel. The surgical device including: a housing; a flexible suture having a looped portion extending from a distal end of the housing for capturing a periphery of the vessel; ligating means for tightening the looped portion around the periphery of the vessel; and a cutter for cutting the vessel. Also provided is a method for ligating and severing a vessel including: looping a flexible suture material around a periphery of the vessel; looping a flexible cutting material around the periphery of the vessel; ligating the vessel by decreasing the size of the loop of flexible suture material; and severing the vessel by decreasing the size of the loop of flexible cutting material. The method preferably further includes drawing the vessel against a cutting surface, such as a knife blade, which is retractable in a housing.
