Insertion protocol for the hemostatic puncture closure device

The hemostatic puncture closure device consists of an absorbable plug component and delivery system. The plug has a lactide and glycolide anchor attached to a 24- to 28-mg collagen sponge by an absorbable suture. The device is contained in a carrier tube. Delivery of the device is initiated by first exchanging the existing sheath over a wire for an 8 Fr sheath. Panels A and B: The carrier tube containing the plug is inserted through the sheath deploying the anchor within the arterial lumen. Panel C: The sheath and carrier tube assembly are then retracted, maintaining tension on the assembly while pushing down the tamper tube. Panel D: Through use of a tension spring, traction is maintained along the suture line, resulting in plugging of the anterior arterial wall puncture site by the anchor and collagen plug. After 20 minutes, the tension spring is removed and the suture is cut below skin level.
