## Indications for use
The LigaSureTM Open Dissector Divider is a bipolar electrosurgical instrument intended for use with the LigaSureTM Generator in open, general, surgical procedures where dissection, ligation and division of vessels is desired. This device creates ligation by application of bipolar electrosurgical RF energy and pressure to vessels/tissue interposed between the jaws of the device. The ligation can then be transected using the built in cutting mechanism. The device can be used for vessels up to and including 7 mm in diameter and tissue bundles as large as will fit into the jaws of the instrument. Indications for use include general, open procedures including urologic, vascular, thoracic, and plastic and reconstructive, procedures where dissection, ligation and division of vessels are performed such as: spleenectomies, thryoidectomies, nephrectomies, prostatectomies, bowel resection and colectomy. The LigaSure Vessel Sealing System has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures, and should not be used for these procedures.
