A ligation clip includes a first jaw, a second jaw, and a hinge. The first jaw has a body having an inner surface defining a first clamping surface and an outer surface. The second jaw has a body having an inner surface defining a second clamping surface and an outer surface. The hinge is integrally formed with the first and second jaws and includes an inner hinge portion and an outer hinge portion. The inner hinge portion has an inner surface that is contiguous with the first and second clamping surfaces of the first and second jaws, and an outer surface. The inner surface of the inner hinge portion is defined by a plurality of curved sections. The hinge is configured to facilitate pivotal movement of the first jaw in relation to the second jaw between an open position and a clamped position.
