Which closure device uses a non-absorbable nitinol clip to seal the arteriotomy?

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

Answer: (A)

Closure after femoral arterial access can be achieved with different mechanisms: suture-based, collagen plug–based, or clip-based. The key feature of the clip-based approach is deploying a small nitinol clip across the arteriotomy that remains in place to hold the arterial edges together.

The device that uses a non-absorbable nitinol clip to seal the arteriotomy is StarClose. It delivers a self-expanding nitinol clip across the puncture to achieve rapid hemostasis, and the clip stays in place as the vessel heals. This design contrasts with suture-mediated closures (which use a knot or suture to close the puncture), collagen plug devices (which seal with a plug that is absorbed), and polymer sealant devices (which seal with a water-activated polymer).
