  • METHOD OF MAKING FLEXIBLE BIORESORBABLE HEMOSTATIC PACKING AND STENT HAVING A PRESELECTABLE IN-VIVO RESIDENCE TIME
    Publication number: 20170119920
    Abstract: The invention provides a method of making flexible bioresorbable foam having hemostatic properties and a preselectable in-vivo residence time. A blend of crosslinked collagen blended and a hyaluronic acid component is prepared. The blend is mixed with water to form a suspension. The blend is freezed and lyophilized at less than about 0° C. Next, the blend is crosslinked. The product is then sterilized and chain scission is performed by bombardment with gamma rays or a beam of electrons.
