Abstract
Przedmiotem zgłoszenia jest proteza do regeneracji nerwów, składająca się z rdzenia o długości 5 - 50 mm, umieszczonego w tulei o kształcie walca o grubości 0,04 - 1 mm i średnicy wewnętrznej 1 - 10 mm. Tuleja wykonana jest z kopolimeru DL - laktyd/glikolid o stosunku molowym 75/25, a rdzeń wykonany jest z chitozanu o średnim ciężarze cząsteczkowym 100 - 500 kDa i stopniu deacetylacji 80 - 98%, przy czym chitozan ma postać pełnych w środku włókien o średnicy 20 - 40 µm. Włókna chitozanowe stanowiące rdzeń są umieszczone w tulei w stanie naprężenia i równolegle do jej osi w ilości od 150 - 22500. Ponadto rdzeń umieszczony jest w tulei tak, że tuleja wystaje poza oba końce rdzenia. Przedmiotem zgłoszenia jest również sposób wytwarzania opisanej powyżej protezy do regeneracji nerwów.
