Vascular Closure Devices
VCDs are classified into two types of closure. Passive closure devices are used to assist in manual compression (MC) by enhancement or promotion of coagulation, by wire-stimulated track thrombosis, or by enhanced manual compression. These devices do not afford immediate closure but improve on manual compression. Active closure devices include collagen-based devices or suture- based devices. These can achieve hemostasis within 5 minutes, with minimal or no MC.
