Which closure device uses absorbable thrombin glue to seal the arteriotomy and tissue track?

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

Answer: (A)

This question is about how closure devices achieve hemostasis after femoral artery access. The Duett closure device stands out because it delivers an absorbable thrombin-based glue into the arteriotomy and the tissue tract. The thrombin glue promotes rapid clot formation, sealing both the puncture in the artery wall and the track through the surrounding tissue, and then is absorbed over time. This mechanism provides chemical hemostasis without leaving a bulky implant in the artery. Other devices use different methods: one relies on an intra-arterial anchor plus an extravascular collagen plug, another uses a hydrogel that swells to seal the tract, and another uses a suture to close the arteriotomy. The distinguishing feature here is the absorbable thrombin glue sealing both the arteriotomy and tissue track, which is why this device is the correct option.
