The Angio-Seal STS PLUS, made of a bio-absorbable collagen sponge as well as a well-crafted absorbable polymer anchor that is linked by an absorbable suture that tightens itself, is primarily used as a vascular closure device. This device is made to seal and grind the arteriotomy between the collagen sponge and the anchor ? the two dominant components. Hemostasis can be achieved mechanically and it can be supplemented by the collagen and its platelet inducing properties. The device comes in 2 sizes ? 6F and 8F. It helps in eradicating the chances that the sheath tip enters, exits or re-enters the vessel wall. It also helps in providing a smoother shift between the arteriotomy and the insertion tip. For good positioning and easy use, the new lock-in hub can fit only one way.
