Which closure device uses an extravascular collagen plug with a polymer anchor intravascular to seal the arteriotomy?

• A. Angioseal closure device
• B. Mynx closure device
• C. Duett closure device
• D. Perclose closure device

Answer: (A)

This item tests how arterial closure devices seal the puncture. The device described uses an intravascular polymer anchor inside the artery paired with an extravascular collagen plug outside the vessel wall, connected to sandwich and seal the arteriotomy. That specific mechanism—an internal polymer anchor with an external collagen plug—belongs to Angio-Seal. The collagen plug sits outside the vessel to occlude the tract, while the polymer anchor inside helps compress the puncture from within as they are tethered together. Other closures use different methods, such as suture-mediated stitches or external sealants without this anchor-plug pairing.
