AI Technical Summary

Benefits of technology

The patent text is discussing a method to prevent sudden bleeding in arteriovenous malformations by implanting metallic microcoils to stimulate the formation of a blood clot. The text explains that various blood elements in the clotting cascade are attracted to metals. The technical effect of this method is to help prevent a sudden hemorrhage in AVMs.

Problems solved by technology

However, to the inventor's knowledge no one has proposed the use of metals in bandages to help stimulate the formation of a blood clot.

Embodiment Construction

[0046]The inventor has found that a hemostatic fabric can be prepared from a composite of metal fibers or metal powder, or combinations thereof, and one or more secondary fibers. The hemostatic fabric made from the composite displays excellent hemostatic properties and fluid absorbency. To further enhance the hemostatic properties of the hemostatic fabric made from the composite, additional blood factors such as thrombin, lyophilized blood cells, lyophilized platelets, fibrin, fibrinogen, or combinations of these, may be added. These additional factors aid in activating the body's natural hemostasis cascade and result in a material that can rapidly arrest bleeding. The inventors have discovered that the combination of metal fibers, secondary fibers, and additional blood factors produce a novel hemostatic fabric that rapidly arrests bleeding, and is useful in situations where large hemorrhages exist or when a patient cannot be immediately admitted to a hospital or trauma treatment ce...

Abstract

Disclosed herein are hemostatic fabrics that include agents, including metal fibers or powders, that can control bleeding and contribute to faster wound healing.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit under 35 U.S.C. §120 as a continuation application of U.S. patent application Ser. No. 13 / 289,453 filed on Nov. 4, 2011 and currently pending, which in turn claims priority under 35 U.S.C. §119(e) as a nonprovisional of U.S. Prov. Pat. App. 61 / 410,191 filed on Nov. 4, 2010. Each of the aforementioned priority applications are hereby incorporated by reference in their entireties.BACKGROUND OF THE INVENTIONField of the Invention[0002]The invention is generally directed to fabrics that include agents that can control bleeding and contribute to faster wound healing.Description of the Related Art[0003]Many products and devices have been developed to control bleeding and yet there remains a significant unmet need for materials that can be applied to sites of hemorrhage to control bleeding. In 2007 the Center for Disease Control reported nearly 124,000 accidental deaths in the U.S. and uncontrolled bleeding is...
