Abstract
Przedmiotem zgłoszenia jest bioaktywny implant zawierający rusztowanie złożone z warstw polimerowych i kompozytowych o budowie włóknistej, które pokryte jest warstwą hydroksyapatytu i wzbogacone w nośnik z substancją biologicznie aktywną, charakteryzujący się tym, że rusztowanie ma strukturę warstwową, na którą składają się warstwy materiału głównego i warstwy materiału elastycznego i w którym to rusztowaniu warstwy materiału głównego stanowią od 50% do 99% ilości wszystkich warstw, tak, że pozostałą ilość warstw stanowią warstwy materiału elastycznego, przy czym materiał główny stanowi kompozyt o osnowie poli (ϵ—kaprolaktonu), o stopniu dyspersyjności w zakresie od 1,7 do 4,3 i maximum piku rozkładu masy cząsteczkowej w zakresie od 40 do 100 kDa, z dodatkiem od 40% wag. do 60% wag. dwufazowej ceramiki fosforanowo—wapniowej, o stosunku masowym hydroksyapatytu i ortofosforanu (V) wapnia 50:50, a materiał elastyczny bazuje na poli(ϵ—kaprolaktonie), o stopniu dyspersyjności w zakresie od 1,7 do 4,3 i maximum piku rozkładu masy cząsteczkowej w zakresie od 40 do 100 kDa, przy czym każda warstwa materiału głównego i materiału elastycznego ma grubość od 0,8% do 0,95% średnicy włókien, z których jest wytworzona, a rusztowanie ma strukturę porowatą, o otwartych porach między włóknami, tworzących trójwymiarową sieć połączonych kanałów, stanowiących od 40% do 80% objętości całkowitej rusztowania oraz zawiera otwór przelotowy o średnicy od 5 do 10 mm. Przedmiotem zgłoszenia jest również sposób wytwarzania bioaktywnego implantu.
