Blood-tight implantable textile material and method of making

摘要

An unmodified textile material is combined with a mixture including a non-colloidal polysaccharide slurry to form a blood-tight implantable textile material. A substantially porous unmodified textile material is impregnated with a biocompatible, bioresorbable slurry to make an implantable textile material, preferably in the form of a vascular graft. Sodium alginate is a preferred polysaccharide to use in the mixture, which serves as a viable alterative to collagen impregnation and coatings of vascular grafts.
