The Evarrest fibrin sealant patch from Ethicon is a flexible sealant patch designed for general hemostasis. It has a durable mechanical structure for integrated clot formation and has hemostatic efficacy upon first-use attempt, according to the company. It doesn’t require preparation, mixing or moistening – and is ready right out of the box. It has a shelf life of 30 months as well. Thousands of woven fibers and active human biologics work together to stop bleeding in tumor bed, liver resection and aortic reconstruction in 3 minutes. When applied, blood passes through the patch and clot formation begins at the bleeding surface and within the patch. The adhesives on the patch form a tight physical seal with tissue and the patch keeps its flexible barrier to bleeding. The patch is fully absorbed in eight weeks.
