Abstract

Wielowarstwowy materiał medyczny przeznaczony na implant do wypełnień kości stanowi co najmniej jeden układ trzech warstw, z których środkową jest warstwa nanowłókien, zaś zewnętrzne warstwy są warstwami włókniny igłowanej z włókien klasycznych połączonymi z warstwą nanowłókien techniką igłowania. Materiał zawiera co najmniej jeden spośród dodatków ceramicznych, węglowych i metalicznych oraz czynnik wzrostu lub lek. Dodatek ceramiczny, węglowy lub metaliczny, w postaci nanododatku, jest zawarty w strukturze warstwy nanowłókien, zaś czynnik wzrostu lub lek, enkapsulowany w mikrosferach z biopolimeru, jest osadzony na powierzchni warstwy nanowłókien. W odmianie wynalazku wielowarstwowy materiał medyczny przeznaczony na implant do wypełnień kości stanowi także co najmniej jeden układ trzech warstw, z których środkową jest warstwa porowata z polimeru biodegradowalnego, w postaci pianki lub w postaci membrany, zaś zewnętrzne warstwy są warstwami włókniny igłowanej z włókien klasycznych, połączonymi z membraną lub pianką techniką klejenia lub prasowania. Materiał zawiera co najmniej jeden spośród dodatków ceramicznych, węglowych i metalicznych oraz czynnik wzrostu lub lek. Dodatek ceramiczny, węglowy lub metaliczny, w postaci nanododatku, jest zawarty w strukturze pianki lub membrany, zaś czynnik wzrostu lub lek, enkapsulowany w mikrosferach z biopolimeru, jest osadzony na powierzchni warstwy pianki lub membrany.A multilayer medical material intended for a bone filling implant comprises at least one system of three layers, the middle of which is a nanofiber layer, while the outer layers are layers of needle-punched nonwoven fabric made of classic fibers, bonded to the nanofiber layer using a needling technique. The material contains at least one of ceramic, carbon, or metallic additives, as well as a growth factor or drug. The ceramic, carbon, or metallic additive, in the form of a nanoadditive, is incorporated into the structure of the nanofiber layer, while the growth factor or drug, encapsulated in biopolymer microspheres, is deposited on the surface of the nanofiber layer. In a variant of the invention, the multilayer medical material intended for a bone filling implant also comprises at least one system of three layers, the middle of which is a porous layer of biodegradable polymer, in the form of a foam or membrane, while the outer layers are layers of needle-punched nonwoven fabric made of classic fibers, bonded to the membrane or foam using gluing or compression. The material contains at least one of ceramic, carbon, or metal additives and a growth factor or drug. The ceramic, carbon, or metal additive, in the form of a nanoadditive, is incorporated into the foam or membrane structure, and the growth factor or drug, encapsulated in biopolymer microspheres, is deposited on the surface of the foam or membrane layer.
