## Indications for use
The LigaSure Curved, Small Jaw, Open Sealer / Divider is a bipolar electrosurgical instrument intended to be used with the ForceTriad energy platform. The instrument is indicated for use in open general surgical procedures where ligation and division of vessels (up to 7 mm in diameter), tissue bundles, and lymphatics is performed, such as urologic, thoracic, plastic, and reconstructive; and including such procedures as bowel resections, gall bladder procedures, Nissen fundoplication, adhesiolysis, etc. The device is also indicated for open ENT procedures in adults (thyroidectomy, radical neck dissection, parotidectomy, and tonsillectomy) for ligation and division of vessels, lymphatics and tissue bundles 2-3 mm away from unintended thermally sensitive structures such as nerves and parathyroid glands. The LigaSure system has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures. Do not use the LigaSure system for these procedures.
