Abstract

Introduction An absorbable device with a self-locking loop was constructed for ligation purposes. It was designed for surgery with details enabling complete haemostasis (zero loop-diameter) and an enhanced tissue grip. The aim of this study was to test the efficiency of the device in ligating an artery, achiving a tight tissue grip and a complete haemostasis. Materials and methods The device (LigaTie®) was manufactured by injection moulding of a blend of absorbable polymers well tolerated by the tissue. The device was used for ligation of the renal arteries in three anaesthetized pigs. The vessel was cut between the kidney and the device. The artery with the attached device was inspected for haemostasis for a minimum of five minutes. The ability of the device to withstand a ligature slip-off was tested with a dynamometer. Results Six renal arteries were ligated with the device. The device was tightened and secured with one hand. Complete haemostasis of all arteries was obtained and verified for a minimum of five minutes. The devices were securely locked into the tissue, i.e. no sliding along the vessels was observed. Discussion/Conclusion This test showed that effective haemostasis and secure ligatures of the renal arteries can be achieved with this device. The device functioned as planned and may facilitate an easier and safer ligation of blood vessels
