Angio-Seal STS PLUS vascular closure device consists of a collagen sponge and a polymer anchor, which are connected by a self-tightening connection suture. This device seals and sandwiches the arteriotomy to achieve a more complete closure. The device mechanically blocks blood flow, which is supported by the collagen's platelet-inducing properties. The sutures, collagen and anchorss can be completely absorbed within 60 to 90 days.
