This 4.5-inch Noon arteriovenous (AV) fistula clamp is a precision-machined manual instrument featuring an active locking mechanism designed to deliver non-traumatic vascular occlusion during hemodialysis access repairs. The smooth, contoured cross-indexing jaws apply uniform compression forces cleanly without causing intimal tearing or mechanical vessel wall structural damage loops. Fabricated from premium surgical steel alloy to ensure lifelong jaw tension consistency and reliable operational hold.
