Ligation Systems

Weck® Hem-o-lok® Polymer Locking Ligation System
Secure-locking Polymer Technology

Confidence You Can Feel

Confidence. That's what the Weck® Hem-o-lok® Polymer Locking Ligation System provides. Confidence created by a ligation system designed for clip security — secure in the applier, locked onto the patient vessel.

Security By Design

The Hem-o-lok® System's unique design and flexible hinge keep the clip firmly seated in applier jaws. The clip's distinct tactile feedback confirms jaw seating and secure vessel placement.

Cool Ligation

Since the Hem-o-lok® System is a cool ligation system, there's no chance of thermal spread to vital structures, a common concern of many surgeons when using energy-based ligation solutions.

Size Ranges to Meet Your Needs

The Hem-o-lok® System is available in a range of clip sizes, including Medium, Medium-Large, Large and Extra-Large. The Hem-o-lok® System allows for ligation of 10 mm vessels through a 5 mm port or 16 mm vessels through a 10 mm port.

Our broad range of applier lengths (including 45 cm endoscopic appliers for extended reach) allows surgeons to deliver clips with control and confidence.
