Passer/Knot Tiers, Ligature, Endoscopic

Definition : Ligature passer/knot tiers designed to push knot loops onto a body structure for a secure tie, usually with negligible pressure, during endoscopic procedures. Passer/knot tiers are typically long, slender, manual instruments with the operative end configured as a moving curved hook, a shaft appropriate for introduction into the working channel of an endoscope, and a handle at the proximal end with a mechanism to manipulate and tie the ligature. Endoscopic ligature passer/knot tiers are frequently used to suture internal wounds and/or to ligate polyps.
