The type of arterial hemostasis system that places a collagen patch at the puncture site is which of the following?

The arterial hemostasis system that utilizes a collagen patch at the puncture site is known as Angio-Seal. This device is designed to facilitate rapid hemostasis after vascular procedures by applying a collagen patch over the arterial puncture. Collagen is a natural component that assists in the clotting process, promoting rapid healing and sealing the puncture effectively.

Angio-Seal works by being deployed to the site of arterial access, where it provides a scaffold that accelerates the body's healing response. The collagen patch enhances the natural coagulation process, reducing the time required for hemostasis and minimizing the risk of complications related to bleeding.

In contrast, the other systems mentioned do not specifically utilize a collagen patch for hemostasis at the puncture site. Understanding the unique mechanisms of each device can aid in selecting the appropriate system based on the clinical needs during vascular procedures.
