Arterial puncture closure using a collagen plug, I. (Angio-Seal).

Closure devices can generally be categorized by their mechanism of obtaining hemostasis. Currently, devices are either suture-based, collagen-based, or utilize a combination of technologies. They can also be classified on the basis of whether or not they have an intravascular component or exclusively extra-vascular components. The devices that are currently available differ markedly in their mechanism of action, deployment, advantages, and disadvantages. In this article, we will review in detail the Angio-Seal closure device, review some of the current literature regarding this device, and assess its complications, advantages, and disadvantages.
